Not Every Jaw Fits the Same Formula — All-on-X Adapts to You
All-on-X is the evolution of the All-on-4 concept: rather than committing to exactly four implants per arch, the clinician places whatever number of implants your jaw needs for the strongest, safest result. For some patients, that is four. For others, it is five, six, or even eight. The "X" represents a variable — a personalized approach driven by your bone density, bite force, arch shape, and long-term goals.
The rationale is practical. A patient with dense, thick bone and a normal bite might do perfectly well on four implants. But someone who grinds their teeth heavily, has uneven bone distribution, or needs a longer prosthesis might be better served with six implants to reduce per-implant stress and minimize cantilever extensions. Dr. Ostovar makes this determination during CBCT planning, using bone density measurements and digital load simulations to calculate the ideal number and position of implants for each arch.
The surgical and prosthetic workflow is similar to All-on-4: implants are placed in a single visit, often with immediate loading of a provisional prosthesis. The difference is that you are not forced into a one-size-fits-all framework. If Dr. Ostovar sees an opportunity to add an implant in a particularly dense area of bone, he does it — because that extra anchor point translates to better long-term stability and a more conservative prosthetic design. Think of All-on-X as All-on-4 without the arbitrary limitation.

Recovery & Healing Timeline
Understanding the healing process helps you plan ahead and follow post-operative instructions for the best possible outcome.
First 48 Hours
Mild swelling and tenderness are normal. Apply ice packs in 20-minute intervals and take prescribed or over-the-counter anti-inflammatory medication. Eat soft foods and avoid the surgical site when chewing.
Days 3 to 7
Swelling peaks around day three and then improves. The tissue begins closing over the surgical site. Continue with soft foods and use any prescribed antimicrobial rinse. Most patients return to normal activities during this phase.
Long-Term Healing
Surface tissue heals within two to three weeks. Bone integration and deep healing continue for three to six months. Avoid smoking, follow up as scheduled, and maintain good oral hygiene throughout recovery.
Questions during recovery? Call us at (503) 822-0096. We are available for post-operative concerns.
Why More Implants Can Mean Less Stress Per Implant
The mechanical stress on each implant is inversely proportional to the number of implants sharing the load. In a four-implant arch, each implant bears approximately 25 percent of total occlusal force, plus additional cantilever moments at the distal extensions. Adding a fifth or sixth implant distributes that force more evenly and shortens or eliminates cantilever segments, which are the most biomechanically vulnerable parts of any full-arch prosthesis. Finite element modeling shows that six-implant configurations reduce peak stress at the bone-implant interface by 20 to 40 percent compared to four-implant designs in the same arch. For patients with bruxism or reduced bone quality, this stress reduction can be the difference between long-term success and overload failure.
Why Choose a Specialist?
Deciding between four, five, six, or more implants requires nuanced clinical judgment that no algorithm can fully replicate. It demands intraoperative decision-making — assessing primary stability in real time, reading the bone as the osteotomy progresses, and knowing when to add an implant or change an angle. Dr. Ostovar's approach is to plan for the best number digitally but remain flexible during surgery. His 15-plus years of implant experience means he can read torque values, assess bone quality by feel, and make immediate adjustments that benefit you. That surgical intuition is built through thousands of cases.

From Dr. Ostovar: What I Tell My Implant Patients
“In my experience placing thousands of dental implants, I’ve found that the patients who do best are the ones who understand what they’re getting into. It’s not a painful procedure — most people tell me it was easier than the extraction. But it is a process. You’re looking at 3-6 months from implant placement to final crown, sometimes longer if we need to build bone first.
I won’t sugarcoat it: not every patient is a candidate right away. If you’ve had teeth missing for years, you’ve likely lost bone. That doesn’t mean you can’t get implants — it means we may need a bone graft or sinus lift first. I’d rather take the time to build a solid foundation than rush and risk failure.
The materials matter too. We use Nobel Biocare and Straumann titanium implants — these are the systems with the best long-term research behind them. For the crown, I typically recommend zirconia or e.max porcelain depending on the location in your mouth. Front teeth get a different material consideration than molars.
If you’re comparing costs, a single implant at our Beaverton office runs $3,500-$5,500 including the crown. That’s competitive for the Portland metro area, and we offer CareCredit 0% financing. Most PPO dental insurance plans now cover a portion of implant costs — our team will verify your benefits before we start.”

Frequently Asked Questions
What does the "X" in All-on-X stand for?
The "X" represents a variable number of implants. Instead of committing to exactly four implants like All-on-4, All-on-X uses whatever number — four, five, six, or more — that your specific anatomy and needs require. It is a philosophy of personalized treatment rather than a fixed protocol.
How is All-on-X different from All-on-4?
All-on-4 is a specific protocol using exactly four implants with two tilted posteriorly. All-on-X is a broader concept that may use four, five, six, or more implants based on your individual bone quality, bite force, and anatomy. The surgical approach is similar, but All-on-X allows more flexibility in planning.
How does Dr. Ostovar decide how many implants I need?
The decision is based on your CBCT scan results, including bone density measurements at each potential implant site, your bite force patterns, the length of the arch to be restored, and whether you have bruxism. Dr. Ostovar uses digital planning software to simulate different implant configurations before choosing the best one.
Does more implants mean a longer surgery?
Each additional implant adds approximately 15 to 20 minutes to the procedure. Going from four to six implants might add 30 to 40 minutes total. Given that the surgery already takes two to four hours, this small addition is negligible in terms of patient experience, especially under IV sedation.
Is All-on-X more expensive than All-on-4?
Each additional implant adds $1,500 to $2,500 to the total cost. A six-implant arch might cost $3,000 to $5,000 more than a four-implant arch. However, the added implants can improve longevity and reduce the risk of complications, which may save money on repairs and revisions over the decades.
Can All-on-X be done with immediate teeth like All-on-4?
Yes. Immediate loading — receiving provisional teeth the same day as surgery — works with any number of implants as long as each achieves adequate primary stability (typically 35+ Ncm insertion torque). In fact, having more implants can make immediate loading safer because the force is distributed more broadly.
Who is a better candidate for All-on-X versus All-on-4?
Patients with bruxism, softer bone, a long edentulous span, or a history of implant complications may benefit from additional implants. Younger patients who will use their prosthesis for decades may also benefit from the added structural redundancy. Dr. Ostovar makes individual recommendations after analyzing your CBCT data.
What if I already have All-on-4 — can more implants be added later?
Yes, supplemental implants can be added to an existing All-on-4 case, though this requires a new surgical procedure and possibly a new prosthesis to incorporate the additional connections. It is preferable to place the best number initially, but retrofitting is possible when needed.
Does All-on-X use the same type of implants as All-on-4?
Yes. Standard endosseous titanium implants from established manufacturers like Nobel Biocare, Straumann, or BioHorizons are used. The implant type, diameter, and length are selected individually for each position based on the available bone. The prosthetic connection system is the same.
How long does the All-on-X prosthesis last?
With additional implant support, the prosthesis may experience less stress and potentially last longer than a standard four-implant version. Zirconia prostheses on five or six implants routinely last 20 years or more. The implants themselves are expected to last a lifetime with proper maintenance.
What are the risks of having too few implants?
Under-engineering a full-arch case can lead to excessive stress on individual implants, prosthesis fracture at the cantilever, screw loosening, and accelerated bone loss around overloaded implants. These complications are avoidable with proper planning and an adequate number of implants for the specific patient.
Is there a maximum number of implants for a full arch?
Practically, eight implants is the upper limit for most full-arch cases. Beyond that, you run into issues with inter-implant spacing and diminishing returns on load distribution. Most patients fall in the four-to-six range. Dr. Ostovar rarely recommends more than six unless the clinical situation specifically warrants it.
Can All-on-X work in both the upper and lower jaw?
Yes, and the best number may differ between arches. The upper jaw typically has softer bone and may benefit from five or six implants, while the lower jaw often does well with four due to its denser cortical bone. Dr. Ostovar tailors each arch independently for the best result.
What type of prosthesis is used with All-on-X?
The same options available for All-on-4 — acrylic with titanium framework for the provisional phase, and either acrylic or milled monolithic zirconia for the final prosthesis. We recommend zirconia for its superior strength, aesthetics, and longevity, especially when supported by five or more implants.
How do I know if All-on-X is right for me?
A CBCT scan and consultation with Dr. Ostovar will determine the ideal approach. He will show you the digital plan, explain why a specific number of implants is recommended for your anatomy, and provide a detailed cost comparison. The consultation is the first step to a personalized treatment plan.
