What Is All-on-X?
The "X" represents the number of implants used to support the full arch, typically four (All-on-4®) or six (All-on-6®). The right answer for any patient comes from a clinical exam and 3D imaging, not from a marketing menu.
All-on-4®
Four implants per arch support a fixed set of teeth. Posterior implants are angled to take advantage of dense anterior bone. Widely studied and well-documented protocol. Learn more →
All-on-6®
Six implants per arch distribute force more broadly. Often preferred when bone density allows, for added stability and long-term structural support. Learn more →
Customized All-on-X
Number, position, and angulation of implants planned around the patient's anatomy using CBCT 3D imaging. Not every case is a four-implant case. Compare options →
How the All-on-X Process Works
Full-arch implant treatment is a multi-stage process. Setting clear expectations from the start is part of how a specialist practice approaches every case.
Consultation and 3D Imaging
Clinical exam, CBCT 3D scan, and review of medical history. We plan every implant case, from a single implant through full-mouth reconstruction, on a CBCT scan. The goal of the first visit is to understand the patient's situation clinically, not to sell a procedure.
Treatment Planning
Detailed plan developed using digital tools to determine implant number, position, angulation, and the design of the final prosthesis. Patient walked through every step before treatment begins.
Surgical Placement
Implant placement following the CBCT-based plan, with surgical guides where indicated and sedation options for comfort. A fixed temporary prosthesis is provided during the healing phase so the patient maintains function and appearance while osseointegration progresses.
Final Restoration
After osseointegration, the final prosthesis is designed and fabricated in the in-house laboratory, engineered for fit, aesthetics, and long-term function.
Why Specialist Training Matters for Full-Arch Cases
Full-arch implant treatment is one of the most demanding procedures in implant dentistry. The same procedure produces very different long-term outcomes depending on who plans it, who places the implants, and how the final prosthesis is engineered.
-
One Plan From Start to Finish
The case stays within one specialist practice and one treatment plan, from initial planning through final restoration. No transfers between practices.
-
Bone Preservation Is Part of the Plan
Implant position and prosthesis design influence how the jawbone responds to function over time. Specialist planning accounts for that.
-
Customized, Not Templated
Every case is built around individual anatomy, bite, and aesthetic goals. The number of implants, position, and prosthesis design are determined clinically, not by a corporate protocol.

Dr. Marlin holds 9 U.S. patents in dental implant restoration methodology. A depth of research that is unusual in private practice and informs how full-arch cases are engineered.
Who Is a Candidate for All-on-X?
Full-arch implant treatment is appropriate for a range of situations. The right answer for any patient comes from a clinical exam and 3D imaging, not from a phone consultation or marketing material.
Patients Missing Most or All of Their Teeth
Lost most teeth or wearing a denture that no longer fits well. All-on-X restores a fixed set of teeth supported by implants.
Patients With Failing Existing Dentistry
Remaining teeth, crowns, or bridges no longer restorable. Full-arch implant treatment can replace an entire arch in a planned single course of treatment.
Patients Who Want a Fixed Solution
Unlike removable dentures, All-on-X teeth are anchored to implants. They stay in the mouth and function more like natural teeth in chewing, speech, and stability.
Patients Seeking a Second Opinion
Received a full-arch treatment plan from another practice and want a specialist's review before committing? A consultation can clarify your options and expected outcomes.
All-on-X vs. Traditional Dentures and Bridges
Patients researching full-arch options frequently consider three categories: traditional removable dentures, implant-supported overdentures, and fixed All-on-X. The differences are significant.
| Criterion | Traditional Dentures | Implant Overdentures | All-on-X (Fixed) |
|---|---|---|---|
| Retention | Suction, adhesive | 2-4 implants, snap-on | 4-6+ implants, fixed |
| Removable | Yes, daily | Yes, daily | No |
| Bone preservation | None | Partial | Yes |
| Food restrictions | Significant | Some | None typical |
| Speech adaptation | Often required | Some | Minimal |
| Long-term cost | Multiple replacements | Moderate | Higher initial, lower lifetime |
| Stability under chewing | Variable | Improved | Closest to natural teeth |
Material Options for the Final Prosthesis
The final All-on-X prosthesis can be fabricated in several materials, each with trade-offs. The most common are an acrylic-hybrid prosthesis (titanium framework with acrylic teeth) and a monolithic zirconia prosthesis. Material choice influences strength, aesthetics, weight, repairability, longevity, and cost. The full comparison is on the zirconia vs. acrylic full-arch prosthesis page.
Patient Concerns Specific to Full-Arch Treatment
Patients evaluating All-on-X often share several recurring concerns. Each is addressed during consultation and worth knowing in advance.
“I do not want to lose all my teeth if some can be saved.” Specialist evaluation establishes which teeth, if any, have a reasonable long-term prognosis. Full-arch treatment is recommended only when the remaining teeth are not retainable or when retaining them would compromise the long-term outcome of the rehabilitation.
“I had a treatment plan from a corporate clinic and want a second opinion.” Second-opinion evaluations are a common reason patients come to Elite Prosthetic Dentistry. The goal is clarity, not a sales pitch.
“I do not want to be a number in a corporate operation.” A specialist-led practice is structurally different. Dr. Marlin meets the patient and leads the plan, and the surgery and final restoration are coordinated within one practice.
“I am concerned about long-term maintenance.” Maintenance is part of the planning conversation. Material selection, prosthesis design, and home care protocols all influence what long-term maintenance looks like.

When Elite Prosthetic Dentistry Is a Strong Fit
A strong fit if you are looking for
- A clear explanation of when four implants, six, or a different design is the right choice for your arch
- Full-arch treatment where preserving bone and, where possible, natural teeth is part of the plan
- A prosthesis designed for bite, speech, and lip support, not only for the day it is delivered
- Failing full-arch work evaluated independently before a replacement is attempted
- Integrated prosthodontic care from implant planning to final restoration, with the in-house laboratory
The honest boundary
Elite Prosthetic Dentistry may not be the right fit if you are primarily looking for routine insurance-based dentistry, the lowest-cost option, or a quick single-visit solution without a comprehensive evaluation.
Frequently Asked Questions
Frequently Asked Questions
What does the 'X' in All-on-X mean?
The X is a placeholder for the number of implants used to support a full arch of fixed teeth, most commonly four (All-on-4®) or six (All-on-6®). The right number depends on bone quality, bite forces, arch anatomy, and the case plan. The decision is made during diagnostic workup, not chosen from a marketing menu.
Is All-on-X the same as All-on-4 or All-on-6?
All-on-4® and All-on-6® are specific full-arch protocols, both falling under the broader All-on-X category. All-on-4 uses four implants per arch; All-on-6 uses six. All-on-X is the umbrella term used when the final implant count is determined by the patient's anatomy rather than a fixed protocol.
How long does All-on-X treatment take from start to finish?
Most full-arch cases take three to six months from surgical placement to final restoration. A fixed temporary prosthesis can frequently be placed the day of surgery, so patients are not without teeth during osseointegration. Final restoration is designed and fabricated in the in-house lab after the implants have integrated.
Will I be without teeth during treatment?
Not for the duration of treatment. A fixed temporary prosthesis is placed during the surgical and healing phase so the patient maintains function and appearance while osseointegration progresses. The final restoration replaces the temporary after the implants have integrated, typically three to six months after surgery.
Is All-on-X permanent?
The implants are designed to be permanent. The prosthetic teeth attached to them are durable but, like any restoration, may require maintenance, refinishing, or eventual replacement depending on materials selected. Long-term predictability depends on planning, placement, prosthesis design, and ongoing maintenance.
Why see a prosthodontist for full-arch implants instead of a corporate implant chain?
Full-arch implant treatment is one of the most complex procedures in implant dentistry. Specialist prosthodontic training, coordinated surgical and restorative treatment, in-house lab control, and individualized planning have measurable effects on the long-term outcome. Patients comparing options often want to understand the difference between specialist and corporate models before committing.
