Implant Supported Full Arch Restorations

All On X Dental Implants: Single or Double Arch Full Mouth Reconstruction

Understanding the All on X “Fixed Implant Supported Denture” vs Traditional Removal Denture

Without question, the optimal solution for any edentulous (toothless) patient from whom it is still clinically viable to place implants, is the All on x Dental Implant Solution. Whether All on 4, All on 5, All on 6 or any variation of a full arch implant supported design, there is not second best option for quality of life,  long term durability, bone maintenance, health improvement, perfunctory improvement and frankly happiness. The fixed implant-supported prosthesis presents numerous advantages over traditional removable complete dentures. The surgical protocol that Dr. May employs for delivering these full-arch All on X restorations is relatively simple, and the positive impact this treatment definitively has on patients cannot be overstated. All on X Implant supported full arch restorations are nothing short of life changing. Patients who have suffered from tooth loss (edentulism) for years, regardless of whether it was induced by trauma, periodontal disease, negligence or any other factor are simply thrilled when they experience the improved quality of life offered by a beautiful, natural feeling, implant supported fixed restoration like a hybrid or a bridge.2,3

What are the benefits of All on X Dental Implant Hybrid (prosthesis) compared to a removable denture?

  1. By stabilizing the prosthesis with dental implants to the maximum degree possible, the dental implant solution effectively restores full oral function, comfort and esthetics, while minimizing bone loss and the devastating soft-tissue changes associated with edentulism.1
  2. Dentures reduce mastication function, speech function, and over time contribute to excessive bone erosion, changing both the dimensions of the jaws and negatively impacting all esthetics of the face.
  3. Removable Dentures typically are made of PMMA or acrylic material which to which plaque and bacteriostatic elements accumulate making it a less than hygienic option.

Fixed hybrid implant supported prosthetics also knowns as “All on X” attach to dental implants via screws, inserted through a titanium or ceramic substructure (frame), have been used to successfully restore fully edentulous patients for decades and are known to be lower cost. Fixed hybrid dentures are typically made of acrylic materials, which after years of experience, Dr. May and other top restorative dentists determined are suboptimal as long term restorative solutions. The acrylic fixed hybrid dentures’ durability and aesthetics, leave much room for improvement, which is why Dr. Yuriy May offers full arch implant supported zirconia prosthesis restorations.

There are three issues that can complicate the long-term success of the traditional fixed hybrid denture:

  • the acrylic teeth tend to wear and looks less life-like (mimicking teeth)
  • the teeth can fracture or dislodge from the acrylic base
  • the acrylic base itself can fracture

The All On X Dental Implant based Full-Arch Implant Prosthesis used by Dr. May eliminates these issues, providing a restoration that is more durable in the long term, while sacrificing nothing when it comes to aesthetics.

World’s Best Fixed Dental Implant Supported Full Arch | All On 6 Dental Implants

Dental implants as a foundation for fixed full-arch prostheses has substantially and dramatically enhanced the quality of life for patients with missing teeth, especially compared to removable dentures.1 Wether considering an All on 4 or an All on 6 Dental Implants, the results are life changing for many of Dr. May’s patients. For many years now, Dr. May’s edentulous (toothless) patients along with those patients experiencing conditions warranting the removal of their remaining teeth (think: severe periodontal disease, bone loss or decay) have opted for having dental implants placed placed to retain beautifully made implant-supported prosthesis also known as a bridge. The superiority of ALL ON X fixed full-arch implant restorations compared to conventional dentures cannot be overstated: it is simply life changing, as Dr. May’s patient’s declare time and time again.

Why Are Implant Supported Dentures So Much Better than Removable Dentures?

By dramatically increasing prosthetic stability, implant-supported full-arch restorations significantly improve chewing ability, taste of food and speech function.2 The positive impact of All on X implant-supported dentures on oral health, comfort and the incredible esthetics offered to edentulous (toothless) or severely compromised dental patients is accompanied by social and psychological benefits as well as improved personal confidence.3 At the same time, the long term benefit of dental implant supported full-arch prosthesis are significant for maintaining long term health:

  • the dental implants help retain bone of the jaws
  • the dental implants help retain use of normal masticating muscles maintaining normal oromyofunctional musculature creating a more youthful facial appearance unlike dentures
  • dental implant induced bone maintenance helps patients look younger look through the mitigation of bite collapse and skin sagging due to jaw bone loss,
  • dental implants help the mitigation of gingival recession,
  • dental implants help prevent bone collapse and masticating pressures from compressing the lower jaw inferior alveolar nerve
  • ultimately helping to preserve the shape of the patient’s mouth and facial structures.4

Fixed Implant Supported Full Arch Prosthesis – What Kind is the Best?

While both removable and fixed implant-supported prostheses provide wide-ranging benefits for toothless patients, fixed restorations have demonstrated superior impact on oral health, dental function, patient satisfaction, and quality of life.5,6 For this reason, the a dental implant supported denture has long been considered the optimal choice for full-arch restorations. Patients can choose between 2 options full the full arch denture:

What does “All on 4 Implants” or “All on 6 Dental Implants” Mean?

The terminology “All On 4” refers to full mouth reconstruction cases for a single arch, as in implants placed in the maxilla (upper arch) or mandible (lower arch).  Specifically “All on 4 Dental Implants” means that “All” the teeth of the prosthetic (typically 10-12 prosthetic teeth per arch) will be placed on the “4” dental implants that are the only fixed anchorage devices holding the prosthetic  (denture) to the implants to create the “teeth”. All on 4 means that the implant dentist will remove all remaining teeth or if the patient already has no remaining teeth, only 4 dental implants will be surgically placed into the jaw. On the 4 dental implants, which will be the only anchorage devices in the upper or lower jaw, “All” the teeth of the prosthetic will be placed on the 4 dental implants.

Similarly, All on 6 Full Arch Prosthetic or All on 6 Surgery means the dental implant specialist like Dr. May will place 6 implants into one of the jaws and then attach a full prosthetic with “all” the teeth for the arch to the 6 dental implants.

Often, skilled and experienced dental implant surgeons like Dr. Yuriy May perform any All on X dental implant case that is suited for each individual patient and their clinical situation. Dr. May has done All on 4, All on 5, All on 6 and All on 8 cases today, highlighting the importance of finding a surgeon who is fluid, experienced and has the ability to customize the number of dental implants for each patient given their clinical presentation.

Which is best? All on 4 vs All on 6 Dental Implants 

Ideally, its always better to place more implants than less implants for an All on X case, thus 6 is generally better than 4, but the number of implants placed is typically dictated by the patient’s bone levels and the amount of surgery they want to undergo. Most of the time, patients don’t choose to do All on 4 and only pursue that option when their bone is severely compromised or they want to avoid additional grafting or sinus lift surgeries.

In reality, the most common of the “All on X” dental implant cases is the placement of 6 implants, because it is an “even” number therefor symmetrical as in 3 on one side of the midline (middle of the jaw) and 3 on the other side of the midline. In the most ideal situations, that aren’t compromised by bone loss or dropped sinuses, Dr. May places at least 8 implants per jaw due to better prosthetic design and bite force distribution,  better bone retention over time, and more long term survivability of the implants and prosthetic. In the most compromised dental patients, Dr. May places a minimum of 4 dental implants utilizing the “All on 4” technique. This is typically done to avoid either performing sinus lifts in the back of the upper jaw or because too much bone is lost in the posterior region. The downside with All on 4 dental implants is in case 1 implant fails, the entire prosthetic is put at risk. In the case of an All on 6 dental implants case when 6 dental implants are placed, if one implant fails immediately or over time, the remaining 5 dental implants can still fully support the prosthetic. In the case of a single implant failure in a 4 dental implant case, surgery has to be done again to place more implants.

The All on 6 implant surgery is the most common of all because most individuals who have lost bone or teeth tend to lose teeth in the posterior region (the back teeth) first, and over time also lose bone in those areas. This means that there is typically enough bone to only place 6 or in the worst cases of posterior (back teeth) bone loss, 4 dental implants for the full arch.

Which All on X Dental Implant Prosthetic Is Best? 

Zirconia Prosthetic Bridge or Denture:  Best Option

  • Benefits of Ceramic Prosthetic: Highly durable, little chance of fracture or breakage, low plaque adhesion making it the most hygienic prosthesis. Highly esthetic. Requires minimal bone reduction and prosthetic is thinner and more comfortable for the patient.
  • Disadvantages of Zirconia Bridge: More expensive
  • Maintenance: Virtually none. Use hydro-flosser daily to clean under and around prosthetic. See the dental implant specialist, Dr. May 2x a year for cleanings

Acrylic Denture (PMMA):  Low Cost Option

  • Benefits of Acrylic Denture: Lowest cost, acceptable esthetics, lightweight
  • Disadvantages of Acrylic Prosthetic: More prone to breakage and fracture, less hygienic and easily accumulates plaque, less esthetic compared to zirconia full arch prosthetic. For surgical planning, requires more bone reduction because acrylic full arch prosthetics need more thickness than zirconia prosthetics. The acrylic base and prosthetic teeth that form the body of the hybrid denture are prone to wear, chipping and fracture.
  • Maintenance: More hands one than zirconia due to the material being less hygienic and less durable material. Clean often and well. Use hydro-flosser daily to clean under and around prosthetic. Rinse often. See the dental implant specialist, Dr. May for cleanings 2x a year and removal maybe need to remove plaques.

Pekkton Framework with individual Crowns: Highest Cost Option

  • Benefits of Peek: Lightweight, more flexible and can absorb more shock than a zirconia prosthetic, very esthetic due to individual crowns, allows fixing individual crown prosthetics in the future and reduces for pekkton framework cracking/breaking. Highly hygienic like zirconia bridge prosthetic. Patients have a real “life like” experience and can floss between the teeth (crowns.) Highly durable and long lasting, thin and comfortable.
  • Disadvantages of Acrylic Prosthetic: Highest cost option due to need to make individual crowns (10-12 individual crowns is beautiful but requires a larger investment).
  • Maintenance: Virtually none. Use hydro-flosser daily to clean under and around prosthetic. Floss between crowns for “real life teeth experience.” See the dental implant specialist, Dr. May 2x a year for cleanings.

In many cases, a high degree of maintenance is required over the life of the restoration to reinforce the body of the prosthesis. This is because fixed full-arch implant restorations are subject to substantial forces associated with masticatory function, parafunctional habits, and bruxism. In the long term, this often causes hybrid dentures to break down, requiring ongoing main- tenance and replacement of the prosthetic teeth or acrylic base. After years of encountering such issues, Dr. May now only works with and recommends rehabilitating his fully edentulous patients with the Zirconia-Based or Pekkton All on X Implant prosthetics and bridges. Long term, we Dr. May believes its really a more financially conservative option in order to avoid patients spending thousands of dollars for a less esthetic, less durable, less hygienic acrylic denture that ultimately ends up broken.
