Zirconia Implants

A zirconia implant illustration shows the main parts of a zirconia dental implant, depending on whether it is a one-piece zirconia implant or a two-piece zirconia implant.

The primary components include the abutment and the zirconia implant body, which is the portion of the implant that is placed into and fuses with the jawbone.

The MAJOR difference is that Titanium Implants are a METAL ALLOY, which means they may cause allergic reactions, conduct electricity, corrode, and cause galvanic effects (disturb electromagnetic pathways in the body, especially when other metals are present). Metal implants are dark grey and metallic in appearance.

Zirconia dental implants are NOT METAL, and are a 100% ceramic known as zirconia dioxide, which does NOT cause metal allergic responses in the body, and does not corrode and does not conduct electricity, which means no galvanization and no electric disturbance in the body. Zirconia dental implants are considered biocompatible and biointern. Zirconia dental implants are white and look more like natural tooth stumps.

Zirconia implants typically feature a one-piece design, where the abutment and implant screw are fused together, or a two-piece implant design, in which the abutment is permanently cemented to the zirconia implant base. A three-piece design (which is less common) is also available and consists of a zirconia abutment and either a carbon fiber screw (Nobel Pearl) or a metal screw (Straumann Pure) that screw-retains the abutment into the zirconia implant base. Dr. May does NOT use any ceramic implants that contain metal (like Straumann).

Titanium implants typically consist of at least three metal components: the metal abutment, the metal screw that attaches the abutment to the titanium implant base, and the metal implant base itself. Variations in metal dental implants include the ability to attach a a zirconia abutment to a titanium dental implant for a front tooth implant case, which does not minimize the gingival show through of the metal implant in the bone. In addition, mini dental implants made of titanium are generally manufactured as a one-piece design, and tend to be much smaller than traditional titanium implants.

Zirconia implants are exceptionally strong and durable, with long-lasting success rates and stability comparable to titanium implants. SDS’s 2019 annual zirconia implant assessment revealed a fracture rate of 0.2% across all zirconia implant types, including both one-piece and two-piece designs, which is considered excellent among implant materials. Fractures are statistically an extremely rare occurrence, occurring at a rate of just 0.2% according to the SDS 2019 implant assessment.

Zirconia implants are Dr. May’s career passion and clinical expertise, with one of the highest front tooth zirconia implants placed in the USA. More than any other implant placing dentist, Natural Dentistry Center performs front tooth zirconia implant surgery placement and restorations with extremely esthetic and natural clinical restorative results.

Upper Front Tooth Implants:

• Central incisors: #8, #9
• Lateral incisors: #7, #10
• Canines: #6, #11
• Depending On Smile Pattern: #4, #5, #12, #13

Lower Front Tooth Implants:

• Central incisors: #24, #25
• Lateral incisors: #23, #26
• Canines: #22, #27
• Depending on Smile Pattern: #20, #23, #28. #29

Front tooth implants are placed to replace upper or lower front teeth due to infection, trauma, or infected root canals and are considered among the most difficult dental implants to place and restore. The reasons for the increased difficulty and required expertise in front tooth implant placement include thinner bone compared to the jawbone around molars, highly sensitive gingival (gum) tissue that can easily recede if not handled properly, and gingiva that is typically thinner than in other areas of the mouth, increasing the risk of implant show-through. Additionally, dental implants in the front tooth region are more likely to fail due to bone quality and bite forces.

The most challenging aspect of front tooth ceramic implant placement is achieving highly aesthetic results, which leaves zirconia implant dentists like Dr. May with very little margin for error. Successful front tooth zirconia implant placement requires a biologically focused dentist with advanced surgical skill and extensive restorative experience, such as Dr. May.

We offer an entire page dedicated to front tooth ceramic implants, including detailed before-and-after case examples.

Day After Surgery: Optional Post Op Check, and a reapeat of adjunct therapies: High Dose IV-C infusion therapy, ozone insufflation, Photobiomodulation Therapy with bone-healing infrared therapy, another session in a hyperbaric oxygen chamber _{(as long as no sinus lift has been performed)}

After surgery, the patient immediately begins the protocol of antibiotics, probiotics, vitamins, minerals, and peptides chosen to specifically help speed up and enhance wound healing, reduce pain and inflammation, support bone formation, enhance the immune system, and support ceramic implant bone integration.

To understand how vitamin D relates to dental implants, it is important to recognize how critical vitamin D is for overall systemic health and the role it plays in the body. Minerals such as calcium and phosphorus can only be properly absorbed through the large intestine when adequate vitamin D is present. This makes vitamin D a vital component in both maintaining bone health and promoting new bone growth. Individuals with vitamin D deficiencies often experience decreased bone mass and bones that fracture more easily, and they may also be more susceptible to dental implant failure.

After a zirconia dental implant is placed, the process of osteogenesis, also known as bone formation, occurs around the implant site. This newly formed bone is a key part of the post-surgical healing process and is highly dependent on the body’s available resources to support healing and bone regeneration after surgery. The bone that forms around the implant fills the surgical site and allows the implant to fuse with the surrounding jawbone. For an implant to be successful and maintain long-term stability, it must osseointegrate, or “fuse,” with the jawbone.

The process of osteogenesis depends in part on the bioavailability of vitamin D in the body, as well as the presence and adequate levels of other essential minerals such as phosphorus and calcium. Patients with low vitamin D levels may not develop sufficient new bone to properly support and stabilize the implant. Patients who follow Dr. May’s protocol and maintain adequate vitamin D levels, along with other minerals that support healing, have a greater likelihood of forming healthy new bone and may reduce their risk of implant failure.

My Dentist Told Me Ceramic Implants Have Metal In Them

First, let’s correct the statement and clarify the fact: there is no metal whatsoever in a ceramic implant, which is precisely why it is referred to as ceramic and not metal.

Oftentimes, any misinformation on this topic is often provided by practitioners who are undereducated on the topic of metal-free dental implants. If your dentist is not a biologic or holistic dentist and has not placed a substantial number of zirconia implants (often hundreds), it is reasonable to conclude that the information you were given may not have come from a true zirconia implant expert and may be clinically incorrect.

If you are reading this page and find yourself with titanium implants that you would not have chosen had you been given accurate and complete clinical information, it is completely understandable to feel upset or frustrated. We empathize with patients in this situation, as it is deeply frustrating when someone in a position of authority, such as a DMD or DDS, provides misleading information or fails to properly educate patients about all available implant options.

We believe that dental professionals, especially those in positions of clinical authority, have a responsibility to remain informed about FDA-cleared dental materials and to educate patients on their full range of clinical options and viable alternatives.

Unfortunately, many conventional dentists are not properly educated on zirconia dental implants and therefore may unintentionally provide incomplete or incorrect information while still presenting themselves as authoritative sources.

The takeaway is simple: do your own research. And if you’re here, you’re already doing exactly that.

Simply put, most conventional dentists in the United States are not trained in or exposed to premium or alternative dental materials, even though these materials are FDA-cleared, rigorously tested, and widely used by biological and holistic dentists. In many cases, the lack of familiarity with ceramic implants can be traced back to the influence of industry politics and large corporate interests.

Titanium metal implants dominate the dental implant market and represent the “big business” side of implant dentistry. As a result, metal implants have become the mainstream standard within the dental industry. Titanium implants are manufactured and distributed by the largest implant companies, which sponsor implant research, educational programs, and training at dental schools. Dental students and specialists, such as periodontists and oral surgeons, are therefore trained almost exclusively on titanium systems through affiliations with major manufacturers such as Nobel Biocare and Straumann.

Following dental school, new dentists and specialists typically pursue continuing education to learn about additional treatment options not covered in formal education. However, the most heavily attended and promoted continuing education courses and workshops are again sponsored by the major titanium implant manufacturers. These courses benefit from greater advertising budgets, visibility, geographic access, and frequency. In contrast, more specialized and niche courses, such as zirconia implant training, are less frequently offered, less advertised, and often overlooked by newer dentists.

If the dentist “next door” is unaware of zirconia dental implants and does not offer them, there is often nothing within dental school education, mainstream conferences, popular dental publications, or competitive pressures to make younger dentists aware that zirconia implants are even an available option. This creates a cycle in which lack of exposure perpetuates lack of awareness.

Another major reason why so few dentists are familiar with zirconia implants is economic, often referred to as the cost-to-profit equation. Ceramic implant dentists like Dr. Yuriy May invest years in specialized training in zirconia implant placement, biological surgery, and advanced restorative techniques. This education is almost entirely self-funded and requires significant financial investment, travel, and time away from practice. Because patient demand for zirconia implants remains relatively small and competition among zirconia-trained dentists is limited, many dentists are discouraged from pursuing this niche specialty.

Additionally, the metal-free dental implant market differs significantly from titanium implant training due to distinct surgical techniques and material science considerations. Even when conventional dentists become aware of zirconia implants, the extensive travel, weekend commitments, and high costs associated with specialized training often act as deterrents. For the small number of dentists who do pursue zirconia implant specialization, such as Dr. May, the motivation is rooted in a belief in biocompatibility, long-term clinical viability, and providing what they believe to be the best material available for dental restorations and patient health.

Material costs further discourage adoption. FDA-cleared zirconia dental implants can cost significantly more than FDA-cleared titanium implants, sometimes more than ten times as much. For example, some titanium implants can be purchased for as little as $50, whereas the lowest-cost zirconia implants may cost ten times that amount per implant. When dentists charge a fixed implant fee based on market competition, economic incentives often drive them to select lower-cost materials to preserve profit margins. As a result, zirconia implants, being more expensive to purchase and stock, are often excluded from conventional practices.

Because of this widespread lack of knowledge, many dentists tell patients that “zirconia implants are new and unproven,” which is inaccurate. Zirconia dental implants have been FDA-cleared in the United States since 2007 and have held CE approval in Europe for more than 17 years. European clinical literature documents ceramic dental implant development, placement, and research dating back over 70 years.

While much dental implant research focuses on the most recent five to ten years due to advances in design and material engineering, numerous zirconia implant systems have received FDA clearance in the United States over the past decade, with additional brands gaining approval each year. This growth reflects increasing patient demand for metal-free dental implant options.

For further information, we provide a dedicated page reviewing ceramic implant success rates and zirconia dental implant research studies.

Ceramic vs Titanium Implants

The short answer is yes, for many health-conscious or hypersensitive individuals, ceramic implants have less risk of an inflammatory reaction.

Zirconia implants are the implant of choice for many biological and holistic dentists, naturopaths, functional medicine physicians, integrative doctors, and for patients with autoimmune disorders, allergies, or those who are particularly health-conscious.

From a biological and holistic dental perspective, zirconia implants are widely regarded as superior to titanium implants.

• Zirconia dental implants are 100% metal-free and with rarest exceptions, virtually allergy-free
• Zirconia dental implants are white in color, closely resembling natural teeth and offering superior esthetics compared to gray metal implants. Choosing a ceramic implant is most critical for Front Tooth Implants, for esthetics and gingival stability
• Ceramic implants are biocompatible, as zirconia implants do not stimulate a host response in the way metal implants can
• Ceramic implants are bioinert (non-reactive), reducing the likelihood of host response and inflammation around the gums
• Zirconia does not corrode, oxidize, or break down in the way titanium metal alloy implants can
• Zirconia implants do not create galvanic effects (electrical conductivity) like metal implants and therefore avoid potential EMF “antenna” issues
• Zirconia implants have not been shown to cause potential systemic side effects that may be associated with titanium implants
• Zirconia implants are supported by over ten years of research, demonstrating success rates of 96% or higher after ten years
• Zirconia implants have been FDA-cleared in the United States since 2007 and CE-approved in Europe since 2005
• Zirconia implants are made of few metal free bio-inert (non-reactive) ingredients unlike titanium metal alloy implants, which can contain up to 15+ different metals in small amounts.

Zirconia Implants Are for Front Teeth, Canines, Molars - Any Tooth

Zirconia dental implants can be used to replace any missing tooth in the mouth, including front teeth, back teeth, canines, molars, and every tooth in between. The most common use of ceramic implants is for front tooth replacement. Dr. May places more front tooth zirconia implants than nearly any holistic dentist or conventional oral surgeon in the country and boasts the largest before and after front tooth ceramic implant porfolio internationally.* At Natural Dentistry, front tooth ceramic dental implants are a core special focus and are commonly used to replace infected root canals, bridges, and extracted or missing front teeth.


^{*Published January 2025, based on review of over 75 top SDS implant dentists websites and associated IG / FB Pages.}

Why are front tooth (anterior) implants typically done with ceramic instead of titanium implants?

Unlike titanium dental implants, zirconia implants provide a highly natural and aesthetic appearance in the front of the mouth, particularly beneath the gum tissue, and help promote bone growth along the buccal bone. Titanium implants, by contrast, are more likely to contribute to pronounced bone loss, gray metal show-through beneath thin gum tissue, and increased gingival irritation or gum recession around the front teeth.

Secondly, zirconia dental implants are also preferable to titanium implants for every tooth in the mouth, including molars. Zirconia implants are exceptionally strong, do not corrode or oxidize, and are predicted to have a lower incidence of peri-implantitis compared to metal dental implants. Zirconia implants are also observed to experience less bone loss over time, promote healthier gum tissue, and accumulate less plaque than titanium implants.

This reduced plaque accumulation is especially important in the posterior regions of the mouth, where hygienists and dentists most commonly observe plaque buildup. The back molars are notoriously more difficult to clean than front teeth, making reduced plaque adhesion a significant advantage in preventing bacterial growth, biofilm formation, and gingivitis.

Thirdly, ceramic implants are a superior option for replacing any single tooth or an entire full mouth of teeth, as zirconia implants are biocompatible, corrosion-free, and associated with fewer inflammatory responses, reduced long-term bone loss, and a lower risk of long-term implant complications when compared to titanium implants.

Dental implantology is a field that has been largely pioneered and advanced in Europe from both an invention and innovation standpoint. The first titanium dental implant was invented by Swedish researcher Per-Ingvar Brånemark, although it was not tested in human trials until the 1960s. Ceramic implants were introduced into dental implantology around the same time, in the early 1960s, as an alternative to titanium implants, largely due to concerns regarding potential immunologic reactions, allergies, and aesthetic compromises associated with metal implants. Variations of ceramic dental implants have existed in documented clinical dentistry for nearly 70 years since their inception in the late 1960s.

The first ceramic dental implant was developed in 1967 in Europe by Swiss dentist Dr. Sami Sandhaus, shortly after the first human trials of titanium implants conducted during the same decade. Dr. Sandhaus considered ceramic materials to be far more suitable for dental implant use due to zirconia’s near-ideal characteristics, including tooth-like color, favorable mechanical properties, excellent biocompatibility, and low plaque affinity. In 1977, Klawitter published the first paper on alumina dental implants based on animal studies, followed by further research in 1980 on the well-known Tübinger immediate implant, which was a ceramic implant made from aluminum oxide (Al₂O₃).

Alumina ceramic implants developed alongside titanium implants in the 1960s as an alternative treatment option due to their attractive implant characteristics. Alumina implants were among the earliest dental implants trialed because of their high level of bioinertness, superior to metals, which are more reactive, their white, tooth-like appearance, and their proven capacity for osseointegration, meaning their ability to heal and fuse with surrounding bone. Simply stated, early ceramic implants made of aluminum oxide (Al₂O₃) have more than 70 years of documented clinical history and research supporting their use as an alternative treatment for improved esthetics, reliable osseointegration, absence of galvanic effects, reduced plaque adhesion, and a reduced incidence of peri-implantitis (gum inflammation around implant sites).¹², ¹⁴

Over time, the original alumina ceramic implants were largely replaced in the dental implant market by titanium (primarily) and zirconia (secondarily), due to the superior toughness of titanium and zirconia materials. Zirconia offered a distinct advantage in that, like alumina, it is pearly white, while also possessing significantly greater toughness than alumina.

In the 1980s, zirconia-toughened alumina (ZTA) implants replaced alumina implants in research and development and served as the precursor to modern zirconia dental implant materials. Today’s zirconia dental implants are manufactured from Y-TZP (yttria-tetragonal zirconia polycrystals), a high-strength ceramic material with excellent long-term performance in both medical and dental implant applications. These implants are composed of zirconium oxide (ZrO₂) and yttria oxide (Y₂O₃), providing substantial advantages over earlier aluminum oxide ceramics, including significantly higher resilience and flexural strength, while preserving the favorable properties of ceramic implants discovered more than 70 years ago.²⁷, ³³

Both metal-free ceramic implants and titanium implants did not gain widespread acceptance among dentists in Europe or the United States until the 1980s, as dental bridges had long been considered the standard solution for missing teeth. The first of many positive clinical outcomes for ceramic dental implants were reported by Dr. Sami Sandhaus in 1997 for alumina, ZTA, and zirconia implants. Dr. Sandhaus remained a widely respected lecturer, researcher, and clinician in the field of ceramic, metal-free dental implantology until his death in 2019.

Are Zirconia Implants FDA Cleared?

Zirconia dental implants have been CE-approved in Europe for over 17 years and FDA-cleared in the United States for nearly 20 years, with the first zirconia implant receiving FDA clearance in 2007. Ceramic implants have over 70 years of clinical research and development within the field of dental implantology. In fact, the innovation, testing, and clinical development of ceramic implants dates back to the 1960s, occurring alongside the early development of titanium implants.

A common and misdirected myth often repeated by conventional dentists, periodontists, and oral surgeons who primarily place titanium implants is that ceramic implants are prone to fracturing or breaking. This misconception originates from early alumina ceramic prototype research and does not reflect modern zirconia implant technology. This statement is inaccurate, as zirconia dental implants have been shown to fracture at extremely low ratesreported at less than 0.2%*, and demonstrate survivability rates comparable to those of titanium implants in published research.

This misunderstanding persists largely because many mainstream dentists are unfamiliar with contemporary zirconia implant research, modern zirconia implant designs, and the updated list of FDA-cleared zirconia implant brands and models. In reality, an increasing number of ceramic implant systems are receiving FDA clearance and entering the U.S. market. Over the past three years alone, more than six new zirconia ceramic dental implant systems have been approved in the United States, reflecting their growing popularity and increased clinical adoption among dentists.

As noted in the scientific literature:
“Since the end of the 1990s, the form of partially stabilized zirconia (Y-TZP) has been promoted as suitable for dental use due to its excellent strength and superior fracture resistance as a result of an inherent transformation toughening mechanism.” (61)

There are two primary zirconia implant categories, which are available in three design variations:

One-piece zirconia implants

One-piece zirconia implants are manufactured as a single solid unit in which the implant body (the portion placed into the jawbone) and the abutment (the portion that protrudes through the gums) are fused together.

Two-piece zirconia implants

Two-piece zirconia implants consist of a zirconia implant body and a separate abutment that is permanently cemented into the implant body after the implant has integrated with the bone.

Three-piece zirconia implants

Three-piece zirconia implants include a zirconia implant body, a zirconia abutment, and a screw that secures the abutment to the implant body. The screw used in these systems is either a carbon fiber screw (Nobel Pearl) or a metal screw (Straumann Pure, TAV Dental).

While two-piece zirconia implants tend to be more versatile and easier to use in certain restorative situations, they are associated with a higher incidence of breakage at the abutment-to-implant connection point.

Despite this, two-piece ceramic implants remain an excellent option for specific clinical cases where Dr. May determines they are the most appropriate solution.

One-piece zirconia implants are often the preferred choice of experienced zirconia implant dentists and are generally considered superior in terms of long-term stability, improved bacterial profile over time, and an extremely low likelihood of fracture or mechanical failure.

There are over eight FDA-cleared zirconia dental implant brands available in the United States as of 2021, and Dr. May uses nearly all of them depending on the specific clinical situation. Like any dentist with extensive experience in implants, he has preferred systems that he favors based on performance, design, and clinical outcomes.

FDA-Cleared Zirconia Dental Implant Brands Available in the USA

Ceramic Implant Brands Used by Dr. May:

• SDS Zirconia Dental Implants (♥️ Dr. May’s favorite!)
• Ceraroot Zirconia Dental Implants (♥️ Dr. May’s favorite!)
• Straumann Zirconia Dental Implants (only the 1-piece metal-free design)

Ceramic Dental Implant Brands Not Used:

• Z-Systems Zirconia Dental Implants (also known as Zirkolith)
• Nobel Pearl Zirconia Dental Implants (same design as former Zeramex)
• Zibone Zirconia Dental Implants

Read below to learn more than most dentists about which ceramic implant brands are available in the United States, where they are manufactured, and their technical specifications.

Dr. May’s most used zirconia dental implant is SDS Zirconia Dental Implants, which are imported from Switzerland. Dr. May favors SDS ceramic implants because their material composition and wide variety of shapes and designs allow for highly targeted and stable clinical applications. Prior to SDS receiving FDA clearance in the United States in 2019 (after being available in Europe for more than 20 years), Dr. May relied heavily on another Swiss-manufactured implant systems such as Z-Systems. Before the introduction of SDS zirconia implants to the U.S. market, Z-Systems and Ceraroot were considered among the most versatile zirconia implant options available and have been in use in the United States for over 15 years.

Another long-standing favorite of Dr. May is the Ceraroot implant, which is his preferred option for large molar replacements. He favors Ceraroot implants for posterior teeth due to their tooth-like, wide emergence profile, which is especially well suited for replacing large back molars. Ceraroot zirconia implants have been available in the United States since 2011 and are manufactured in Spain. While for many years they have been exclusively available in a one-piece design, in 2025 they began the process to introduce a 2-piece zirconia implant design, which Dr. May is eagerly awaiting FDA clearance for. While the Ceraroot material is manufactured differently from its Swiss-made metal-free counterparts, Ceraroot implants are widely regarded for having one of the most favorable anatomical emergence profiles, making them excellent options for posterior dentition restoration. Ceraroot one-piece implants have also been widely used in Europe since 2004 and in Canada since 2011.

In 2017, Zeramex received FDA clearance and introduced a unique two-piece screw retained zirconia implant solution. Zeramex implants were manufactured in Switzerland and are co-owned by Nobel, a major titanium implant manufacturer and are marketed as Nobel Pearl. Nobel Pearl zirconia dental implants have uniquea two-piece, screw-retained zirconia implant design with a carbon fiber screw. Dr. May no longer places Nobel Pearl ceramic implants due to other implants, specifically SDS ceramic implants being approved in 2019 by the FDA to be available on the USA market and him finding the design favorable to other available implants. At the time of their introduction in 2017, Nobel Pearl was the only two-piece screw-retained zirconia dental implant available in the United States.

While both Z-Systems ceramic implants and Nobel Pearl implants are available in two-piece zirconia designs and are manufactured in Switzerland. Both systems are considered reputable zirconia implant materials and have been incorporated into Dr. May’s clinical practice as soon as they received FDA clearance.
Straumann Pure offers a solid one-piece zirconia implant design that is used by Dr. May. However,

Straumann also produces a less popular two-piece zirconia implant that contains a metal screw and metal abutment. This design is not used at Natural Dentistry, as the practice’s goal is to avoid metal whenever possible. Similarly, TAV Dental implants are available in both a one-piece solid zirconia design and a two-piece metal screw, retained version. The metal-containing versions are generally not preferred by patients seeking fully metal-free dental implant solutions.

Multiple risk factors are carefully evaluated when selecting the optimal zirconia dental implant for each patient, including the specific clinical indication and tooth location. Dr. May continuously evaluates newly FDA-cleared zirconia implant systems and is occasionally invited to beta-test experimental ceramic dental implants being considered for entry into the U.S. market. He is currently serving as a beta tester for select SDS abutments and newly introduced implant designs, including oval and balcony-shaped implants.

General properties of ceramics include high melting temperature, high hardness, high toughness, lack of electrical conductivity, low elasticity, chemical resistance, and low ductility. When considering ceramics in the medical realm, additional defining characteristics apply: ceramics are generally bioinert (non-reactive) and biocompatible, meaning they do not provoke the inflammatory host responses that can occur with metals in the body.

Several material properties originate from elemental characteristics found on the periodic table of elements (yes, high school chemistry). One of the most common sources of misinformation spread about FDA- and CE-approved zirconia implants by conventional dentists is the claim that they are made of zirconium, which is incorrect. While the terms zirconia and zirconium sound similar, they refer to two entirely different materials.

Zirconia dental implants are made from zirconium dioxide (ZrO₂), not elemental zirconium (Zr). When zirconium is processed and converted into ZrO₂, it undergoes a chemical transformation and becomes a ceramic, meaning it loses all of its original metallic properties. Zirconia used in dental implants is chemically defined as Y-TZP (yttria-tetragonal zirconia polycrystals), a high-strength ceramic material composed of zirconium oxide (ZrO₂) and yttria oxide (Y₂O₃).

Putting chemistry aside for a moment (more detailed material science is covered later on this page for those who want to explore it further), the key question remains: why are zirconia dental implants classified as ceramic rather than metal implants?

Zirconia (ZrO₂) has no electrical conductivity, unlike metal materials. This means no galvanism, no electrical current disturbances, and no potential EMF “antenna” effects. By contrast, patients with titanium alloy implants may experience and report PEMF or EMF-related disturbances, such as headaches or nausea, when exposed to high electromagnetic fields. Like glass or wood, ceramic materials do not conduct electricity.

Another critical property of zirconia implants is that they do not corrode. Corrosion is another term for oxidation, which refers to the breakdown of materials and is commonly observed as rust in metals. Zirconia implants are manufactured from zirconia oxide powder that is layered in multiple stages under intense heat and pressure to form a solid Y-TZP block. This block is then precision-milled into its final implant shape.
This manufacturing process significantly increases resistance to fracture and material aging, allowing zirconia implants to be adjusted and prepared in the mouth in a manner similar to natural tooth preparation. Zirconia implant experts like Dr. Yuriy May utilize this capability to shape implants intraorally, creating a highly natural and customized emergence profile that closely mimics that of a real tooth.

Let’s go back in time the famously tragic Titanic ship built of mostly of steel (a metal alloy), decaying at the bottom of the ocean which has almost entirely oxidized and corroded, with little left but rust, dust, and seashells (the ship sunk in April 2012.) Now think of the Roman/Greek liquid containers “Amphorae” used initially by Etruscans to transport mostly wine by ship, are made of ceramic and date back to as early as 5th century BC. The ceramic containers were constructed mostly of clay, specifically terracotta, and fired at high temperatures at a kiln to seal them. Unlike the metal broken down Titanic which drowned in 1912 and was nearly fully corroded by the 1980s, the ceramic amphora wine containers have been recovered from the bottom of the ocean floor after THOUSANDS of years fully intact and STILL found to contain liquid. The CERAMIC containers did not oxidize, corrode or rusk after thousands of years at the bottom of the same (not geographically) ocean. And similar to the ocean, our mouth, is a wet and harsh environment, so which material sounds more time-proof and durable for a dental implant? The metal implant made of Titanium alloy that corrodes and breaks down or the ceramic material, defined as a hard, heat-resistant, and corrosion-resistant material made from a non-metallic mineral, and processed at a high temperature?

No, it does not. All titanium dental implants are made from titanium alloys, which means titanium is always combined with other metals and is never used in its pure form for dental implants.

Titanium, which is the primary material used in metal dental implants, is a metal element (Ti), similar to other elemental metals such as nickel (Ni), aluminum (Al), cadmium (Cd), and vanadium (V). What all of these materials have in common is that they are elemental metals, and many of them are found in metal dental implants. In fact, 100% of titanium dental implants are metal alloys.

A metal alloy is defined as a mixture of two or more elements. This means that titanium dental implants are never made of pure titanium. Pure titanium dental implants do not exist because, both chemically and functionally, titanium alone does not possess the necessary strength, flexural properties, or corrosion resistance required to withstand the forces placed on a dental implant over time.

For this reason, titanium is always combined with other metals to enhance its mechanical performance. However, these additional metals, such as cadmium, vanadium, and nickel, are often implicated as precipitating factors in metal sensitivities or allergic reactions. These are metals that ideally should not be in constant contact with the human body, especially on a 24/7 basis and particularly in an environment like the mouth, where exposure to heat and moisture is continuous.

Why is the selection of Dental Implant Material so important for biocompatibility?

Teeth, restorations, and all dental prostheses, including dental implants, must function in one of the most inhospitable environments in the human body. The oral cavity is exposed to extreme and frequent variations in temperature, pH, moisture, and mechanical stress, far exceeding those experienced by most other tissues in the body.

Corrosion, commonly understood as the breakdown of metal when exposed to oxygen (such as rusting) is formally defined as “the graded degradation of materials by electrochemical attack.” Corrosion of titanium alloy dental implants is a significant concern, particularly because implants are placed in the wet, warm, and chemically active oral environment, often described in the scientific literature as a “hostile electrolytic environment.”

When corrosion occurs, metal ions are released into surrounding tissues. These ions may trigger local or systemic allergic reactions, inflammatory responses, or immune-mediated reactions in susceptible individuals. The present body of research describes multiple manifestations of allergic and inflammatory responses associated with implant materials placed in the oral cavity. (50)

Well-informed and health-conscious patients increasingly recognize the importance of appropriate, biocompatible material selection, which is why many thoroughly research dental implant materials and seek out experienced biological dentists such as Dr. Yuriy May. Before selecting a dental implant material, it is essential to understand that material choice depends on multiple critical factors, including, but not limited to:

1. Metal Particle Corrosion & Galvanization Prevention Metal titanium implants break down and rust (corrode) and zirconia implants do not
2. Mechanical Properties & Durability Titanium and Zirconia Implants break less than 1% with correct implant placement. How long has it been FDA cleared?
3. Cost & Investment Decision Criteria Zirconia Implants are approximately 10-20% more expensive than titanium implants (see our page on cost and research)
4. Success Rates & Complications Both titanium metal and zirconia have 96% survivability rates at 12-year point history research studies
5. Biocompatibility & Autoimmune Response Metal Titanium is considered to be a more inflammatory material and not biocompatible compared to ceramic implants
6. Esthetic Appearance & Tooth-Like Feel Metal implants are unsightly, grey, show through the gingiva, and don’t look like teeth, unlike perfectly white zirconia implants

Thus, for the application of existing and new dental materials, it is essential for the patient and especially the dentist to have a comprehensive knowledge of these attributes.

For decades, oral surgeons and implant dentists have debated whether titanium dental implants may provoke an adverse host inflammatory response. Within biological and integrative dentistry, clinicians such as Dr. Yuriy May have long recognized that titanium implants are not biologically inert and may contribute to chronic inflammation, bone loss, infection, and systemic immune reactions in susceptible patients.

Extensive medical, dental, and biomaterials research has documented a strong association between titanium surface corrosion and hypersensitivity reactions. When titanium dental implants are exposed to the warm, moist, and chemically active oral environment, metal ions are released from the implant surface. These ions can bind to native proteins, forming complexes that act as allergens, triggering immune-mediated hypersensitivity reactions in certain individuals. This mechanism is well documented across allergology, rheumatology, and implant-material research literature. (51 to 57)

Beyond localized inflammation, multiple studies have demonstrated elevated concentrations of titanium particles in peri-implant soft tissues (gingival tissues adjacent to the implant), regional lymph nodes, and even pulmonary tissues in animal models and human observations involving titanium implants, particularly in cases of implant failure. These findings suggest not only a local tissue response but also the potential for systemic distribution of titanium particles through the lymphatic and circulatory systems. (58 to 60)

Clinically, peri-implantitis, a chronic inflammatory condition affecting the tissues surrounding dental implants, is the leading cause of long-term titanium implant failure. In contrast, zirconia dental implants demonstrate a significantly lower incidence of peri-implantitis, reported in long-term studies to be under 2%, likely due to zirconia’s bioinert surface, reduced plaque affinity, and absence of metal corrosion.

Within the dental implant market, ceramic (zirconia) dental implants are often considered the premium option, the equivalent of a high-performance or luxury vehicle, while titanium implants represent the more conventional, mass-market alternative. Ultimately, patients are faced with an important question: Is it worth placing lower-cost, corrosion-prone metal materials into the body’s tissues and bloodstream, or does long-term health justify choosing a premium, metal-free, biocompatible implant solution?

Dental Implant Process & Education

Understanding the dental implant process. Patients considering zirconia dental implants are strongly encouraged to understand the entire implant process, not just the final cost. Dental implant treatment is a multi-step medical and restorative procedure, and long-term success depends heavily on proper diagnosis, planning, surgical execution, and restoration, not simply the implant material itself.

At Natural Dentistry, Dr. Yuriy May follows a comprehensive, biologically driven implant protocol designed to optimize both oral and systemic health outcomes. This process includes:

• Comprehensive diagnosis and treatment planning
• Advanced 3D CBCT (cone beam CT) scan analysis
• Evaluation of bone quality, volume, and anatomy
• Surgical site preparation
• Bone grafting and ridge or bone expansion when indicated
• Precise surgical placement of one or multiple zirconia dental implants
• Abutment integration
• Final crown or bridge restoration using advanced 3D Smile Design technology

The restorative phase allows patients to actively participate in designing the appearance of their final smile, ensuring optimal esthetics, function, and harmony with facial features.

Equally important, meticulous planning and surgical execution play a critical role in preventing long-term complications, such as peri-implantitis, a condition involving plaque accumulation, gum inflammation, and progressive bone loss around dental implants. Proper implant positioning, material selection, tissue management, and restorative design are all essential factors in reducing these risks and supporting long-term implant stability.

Understanding these steps provides necessary context when evaluating zirconia dental implant costs and highlights why treatment outcomes can vary significantly between providers.

The Search for a Better Dental Implant, Why Titanium Isn’t Ideal

Ceramic dental implants, specifically zirconia (also referred to as zirconium dioxide) dental implants, represent a more modern and progressive advancement in the field of oral reconstruction. Their development emerged from the ongoing search for a safer, more biocompatible alternative to traditional titanium dental implants.

What is Titanium? What lurks in the metal of a titanium dental implant?

Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal characterized by its silver color, low density, and high strength. While titanium is resistant to corrosion, it cannot be used as a pure, standalone material to manufacture a dental implant.

As a result, 100% of titanium dental implants are made from metal alloys, not pure titanium. These alloys may include metals such as nickel (Ni), a known metal allergen, as well as copper, steel, vanadium, and aluminum. The presence of these additional metals introduces concerns related to corrosion, biocompatibility, and potential allergic or inflammatory responses in susceptible individuals.

Zirconia dental implants initially gained significant attention among health-conscious patients and biological dentists due to their metal-free composition, superior biocompatibility, and tooth-like esthetics, offering an alternative to metal-based implant materials.

Titanium Implants, Sub-optimal Cosmetic Results in the Esthetic Smile Zone

It is well documented in dental literature that the use of conventional titanium dental implants to replace missing teeth may result in cosmetically compromised outcomes, particularly in the esthetic zone. The esthetic zone is typically defined in dentistry as the anterior teeth and surrounding gum tissue that are easily visible when smiling.

Titanium implants placed in this region may become visible through the thin peri-implant mucosa that covers the front teeth, thereby impairing the desired clinical and esthetic results. This translucency can lead to unaesthetic smile defects in both tooth color and gum appearance, as the dark gray color of the titanium implant may show through the soft tissue.⁵⁻⁷

Additionally, the implant collar or endpoint near the abutment may become undesirably visible over time due to soft tissue shrinkage, gum recession, and peri-implant lesions, also referred to as peri-implantitis.⁵⁻⁸

Titanium Implant Risks: Corrosion, Metal Particle Displacement, Allergic Reactions

Although titanium has historically been described as corrosion-resistant, continued investigation has demonstrated increased concentrations of titanium in bone adjacent to titanium implants.⁹ Additional clinical findings have reported particularly concerning outcomes related to titanium particle release.¹⁰

Studies have documented the accumulation of titanium particles in tissues surrounding dental implant surfaces,⁴² as well as in regional lymph nodes,⁴³ and in other areas of the body.⁴⁴⁻⁴⁵ These findings raise important questions regarding the long-term biological behavior of titanium alloys when placed in a chronically wet, warm, and electrolytic environment such as the oral cavity.

In contrast, when reviewing studies that report negative biological findings associated with titanium implants, it is important to note the general consensus among dental implant researchers regarding the absence of local or systemic toxic effects following implantation of zirconia ceramics. Zirconia dental implants have demonstrated no detectable toxic response when implanted into muscle or bone tissue in various animal models.⁴⁶⁻⁴⁹

In addition to corrosion and particle release, another documented concern associated with titanium dental implants is galvanization. Multiple studies have described galvanic side effects that occur when metal components of a dental implant come into contact with the body’s cellular environment, including saliva, blood cells, soft tissue cells, and bone particles.¹¹

This electrochemical interaction may contribute to localized inflammatory responses and further complicate the long-term biocompatibility of metal-based dental implants.

Titanium Implant Allergies

It is estimated that approximately 3 to 5% of the population may be genetically predisposed to adverse reactions to titanium, which can manifest as titanium implant toxicity. This predisposition occurs because certain genes involved in liver detoxification pathways, pathways that normally assist in processing and detoxifying titanium, may be absent or impaired.

In some cases, genetic testing and metal sensitivity testing can confirm the presence of relevant genetic polymorphisms and/or IgG and IgA antibody reactions, indicating an abnormal immune response to titanium exposure.

Titanium Implant Allergies

Symptoms of titanium toxicity can vary widely and may depend on numerous factors, including the source of titanium, exposure to other metal alloys, accumulation of titanium particles in local tissues (such as around metal implants), duration of exposure, and individual health factors.

Reported symptoms may include:

• Skin diseases (Eczema, psoriasis)
• Vertigo
• Brain Fog
• Headaches/Migraines
• Peri-implantitis around metal implants
• Sinus congestion
• Cancer
• Vision problems
• Lung diseases
• Libido Changes & Sexual Male Oversensitization During Activity
• Bright’s disease (a disease involving chronic inflammation of the kidneys)
• Lupus (any of various diseases or conditions marked by inflammation of the skin)

In-Depth Knowledge Section: Galvanism, What is it and Why Does it Happen in Our Mouth?

Galvanic activity in the oral cavity arises from the interaction of multiple metallic materials with the body’s inherent bioelectrical environment, compounded by the presence of moisture. When dissimilar metals are introduced into this electrically active, saline-rich environment, electrochemical reactions can occur, amplifying electrical disturbances and accelerating metal ion release. Contributing factors include:

• Saliva, which acts as an electrical conductor
• Multiple metal sources, such as amalgam fillings, titanium implants, porcelain-fused-to-metal bridges, gold crowns, surgical steel posts, and other metallic restorations
• Intercellular and intracellular electrical currents

Together, these three factors create a phenomenon similar to an unwanted biological battery, which disrupts, rather than supports, the body’s natural biological processes. When different metals are electrically connected through saliva and influenced by internal cellular currents, electro-current disturbances, also known as galvanization, can occur.

This is why a metal-free mouth is considered the most natural state, allowing uninterrupted microcurrent flow that supports optimal health and regenerative processes within the body. Unlike titanium dental implants, zirconia implants do not corrode, do not alter taste perception, and, most importantly, avoid the health-disrupting effects of galvanization (electrical current disturbances).

Galvanic disturbances may interfere with the body’s energy meridians and intercellular electrical signaling, potentially contributing to or accelerating disease processes. Zirconia dental implants represent the optimal alternative for patients who are uncomfortable with, or unable to tolerate, metal (titanium) implants.

Understanding the Superior Metal-Free, Biocompatible Dental Implant Material and Its Effects on Health, Beauty, Function, and Quality of Life

Zirconia is a very hard material with exceptional strength, making it an ideal choice for dental implant applications.

Zirconia, Chemical Definition

Zirconia (ZrO₂) is a high-performance ceramic dental implant material made from ceramic powder and contains no metal properties.This material is often confused with the metal element zirconium.

Zirconium (Zr) is a metallic element found on the periodic table of elements as atomic number 40, classified within the metal family. In its elemental form, zirconium exhibits traditional metal properties.

Zirconia, however, is chemically defined as Y-TZP (yttria tetragonal zirconia polycrystals), a high-strength ceramic material composed of zirconium dioxide (ZrO₂) and yttria oxide (Y₂O₃) particles. After sintering, it forms a stable tetragonal crystal structure at room temperature. The transformation-toughening mechanism is one of the primary reasons for the exceptional strength and fracture resistance of Y-TZP.28,31,34

Zirconia Implant Material Properties

Y-TZP is a bioinert and non-resorbable metal oxide that demonstrates excellent resistance to corrosion and wear, high flexural strength, exceptional hardness, high fracture resistance, high radiopacity (defined as the inability of electromagnetic radiation to pass through a material), low thermal conductivity, an ivory coloring similar to that of natural teeth, machinability, light transmission properties, and superior biocompatibility.1,2,7,12,27,28,35 to 41

Because of its high biocompatibility, zirconia has been widely used in medicine (including auditory, finger, and hip prostheses) and dentistry (posts, crowns, bridge restorations, implants, and implant abutments). Zirconia closely resembles the natural color of teeth and is biologically compatible, making it an excellent alternative material in dental applications.

Zirconia dental implants were cleared by the FDA in 2007 and are supported by over 50 published clinical studies. They have experienced significant adoption among elite European clinicians and are rapidly gaining popularity in the United States among progressive, cutting-edge dentists who prioritize the use of the highest-quality materials for patient restorations and implant therapy.

Reported Advantages of Ceramic Implants

• Used for over 40 years in medicine, primarily for prosthetic joints and dental implants, with excellent long-term success
• Biocompatible (completely tissue-friendly); no allergic reactions, no temperature sensitivity, and no impact on taste
• Bioinert, meaning they do not cause tissue or bone reactions
• Gum tissue, friendly, with low plaque adhesion and reduced tissue inflammation
• No galvanization side effects
• No corrosion, zirconia dental implant material does not corrode or break down into particulate matter like titanium alloy particles and is therefore self-contained, preventing microscopic or molecular leaching into bodily tissues, as has been reported with titanium dental implants
• Because zirconium is white and closely resembles the color of natural teeth, it offers distinct aesthetic advantages over titanium

In the rare event of gum tissue recession or shrinkage, ceramic dental implants will not reveal gray shadows or lines, as may occur with titanium implants. However, it should be noted that while more technically demanding, excellent aesthetic results can also be achieved with titanium dental implants when placed by highly skilled surgeons who use ceramic abutments and ceramic crowns.

Risks with Zirconia Ceramic Implants

• Zirconia dental implants are available as both one-piece and two-piece FDA-cleared systems and are offered with a variety of abutment designs to provide flexibility in angulation, as well as aesthetic and functional restoration goals.
• While rare, there have been reported cases of non-integration (less than 2%), which is comparable to the failure rates observed with titanium dental implants, as well as occasional implant or abutment fractures. However, long-term clinical studies supporting the efficacy, durability, and longevity of zirconia dental implants provide strong evidence that zirconia implants offer equal or superior clinical advantages compared to titanium implants.
• Zirconia implants may also be subjected to hydrolysis, a physiological process in which the material can absorb water and, in theory, become more susceptible to fracture over time. Although initial and current studies are favorable and indicate that this occurrence is rare, ongoing investigations continue to evaluate this phenomenon to further refine material science and long-term performance.

The Heart of the Matter: Ceramic Implants vs. Titanium Dental Implants?

The decision to use ceramic or titanium dental implants should be fully discussed between dental reconstruction patients and one of the country’s most prominent zirconia implant dentists, Dr. Yuriy May. On one hand, many patients visiting Natural Dentistry specifically request ceramic dental implants because of their benefits as a biocompatible (healthier) and beautiful (more esthetic) dental implant material, as well as their notable metal-free properties. On the other hand, Dr. May always follows evidence-based dentistry to make appropriate recommendations for long-term success and patient safety, depending on the unique circumstances of each clinical case.

The following facts should be considered in the decision-making process:

Zirconia dental implants are considered a “specialty premium implant” in implant dentistry, while titanium is often regarded as the everyday, lower-cost, and most versatile option for dental implant materials. Numerous studies have affirmed the high success and survival rates of zirconia implants, demonstrating 96%+ success rates. Zirconia ceramic dental implants are supported by over 20 years of research, along with distinguished clinical studies and reports in both dental and medical literature. Although titanium dental implants have shown favorable long-term results, their long-term success is generally evaluated at 10 to 15 years, with higher reported incidences of peri-implantitis in cases of long-term failure. (This assessment is based on the interpretation of published study results for both zirconia and titanium implants.)

Titanium implants demonstrate a comparable degree of osseointegration with bone and typically have an excellent prognosis until signs of peri-implantitis (inflammation of the tissues surrounding the implant site) emerge and begin to contribute to implant failure. In contrast, the long-term integration properties of zirconia implants are considered unparalleled when compared to titanium implants, with rare incidences of peri-implantitis, largely due to reduced plaque adhesion and decreased localized inflammatory cytokine activity (e.g., IL-1).

Zirconia implants also offer a distinct aesthetic advantage over titanium implants, not only across all areas of tooth replacement but especially within the esthetic zone. When replacing teeth in the smile zone, Dr. May consistently uses zirconia abutments and ceramic crowns in conjunction with zirconia ceramic dental implants, resulting in highly refined aesthetic outcomes. When gum tissue is thin, as is commonly the case in the anterior (front-of-the-smile) region, the gray shadow of titanium implants may become visible, which can be highly bothersome to patients and lead to compromised esthetics. This potential complication can be avoided by an experienced zirconia implant dentist through appropriate material selection (zirconia), implant size selection, implant positioning, tissue development, timing of implant loading, and premium ceramic crown design.

Finally, zirconia implants may not be suitable for every patient. Limitations may arise due to implant position, bone quality, autoimmune or chronic degenerative disease processes, or functional and biomechanical challenges that must be carefully evaluated on a case-by-case basis.

As a metal, subject to corrosion and galvanic reactions (cellular energy & meridian disturbance)

Zirconia (ZrO2) is a ceramic, non-metal material without any metal properties. It is electrochemically inert causing no galvanizing or electrocurrent disturbance effects at inter and intra cellular level.

Contains traces of metals like Ni, Ai, V, etc

Fully oxidized zirconium (Zr) is known as Zirconia (ZrO2) which is not a metal and does not contain any metals, only ceramics.

Not really an allergen, but triggers intolerances in some patients:

• Increased prostagladine E2
• Increased interleukin 1ß
• Increased TNFα

No known allergies or intolerances. The most bio-inert and bio-compatible material on the USA and European market.

Higher surface free energy:

• Hydrophobic
• Significant plague (biofilm) accumulation=inflammation
• Acceptable soft tissue (gum) health

Lower surface free energy:

• Hydrophillic
• Reduced plague (biofilm) accumulation = less inflammation
• Superior soft tissue (gum) health

• Thinning of gum tissue around implant
• Grey shadow effect showing throung gums (unattractive)
• Does not resemble real tooth structure

Highly desirable esthetic results:

• Healthy, pink and beautiful tissue around implant
• No gum show through, like natural tooth
• Resembles real tooth esthetics

Observed bone errosion over long term and good bone osseointegration

Stimulates bone growth long term with ultimate osseointegration for both bone AND gum, unlike Titanium

Summary of the Desirable Qualities of Zirconia Dental Implants:

Bioinert: Does not interfere with the body’s biological processes. Zirconia is neutral to the body and does not produce negative biological effects, unlike titanium.

Non-resorbable: Cannot be reabsorbed into hard or soft tissue. The material does not deteriorate over time.

Non-corrosive: Does not oxidize like metal and does not break down when exposed to oxygen.

Resistant to wear: Highly durable against abrasion and pressure forces.

High flexural strength: The ability to withstand significant pressure forces before fracture. Also known as bend strength, this material property is defined as the stress a material can endure before yielding or breaking.

High hardness: Unlike malleable metals such as titanium alloys, zirconia maintains structural integrity under high pressure and strong forces without wear or deformation.

Low thermal conductivity: Resists heat transfer and does not conduct heat to adjacent bone and tissue, unlike titanium, which rapidly transfers heat as a metal.

Light transmission: Partially translucent, allowing the transmission of light similar to a natural tooth and enabling biomimetic replication of original tooth aesthetics.

Color: White to ivory in color, closely resembling natural teeth, unlike the steel-gray appearance of titanium implants.
