If you’re in Granite Bay facing the loss of most or all teeth in an arch — or struggling with a denture that slips, clicks, or limits what you eat — All-on-4 dental implants may be the treatment you’ve been looking for. Four implants support a full arch of fixed teeth: no palate coverage, no adhesives, no removal at night. This complete guide explains how All-on-4 works, who qualifies, what recovery looks like, and the honest tradeoffs, from a Roseville prosthodontist experienced in full-arch implant treatment.
What All-on-4 Actually Is
All-on-4 is a full-arch restoration supported by four dental implants (sometimes more, depending on anatomy — the name describes the concept, not a rigid number). Two implants are placed vertically in the front of the jaw, where bone is naturally denser; two are placed at an angle in the back, which lets them engage more bone and avoid the sinuses (upper jaw) or the nerve (lower jaw) without grafting.
A full bridge of teeth — twelve or so teeth per arch — is then fixed to those implants. The result stays in permanently; only your dentist removes it for servicing. One arch or both can be treated.
How It Differs From a Denture — and From Individual Implants
Vs. a conventional denture: no movement, no palate coverage dulling taste, no adhesives, dramatically more chewing power, and the implants slow the jawbone shrinkage that makes dentures loosen over time.
Vs. an implant for every tooth: far fewer implants (and therefore less surgery, lower cost, and often no bone grafting), with comparable daily function. You don’t need eight or ten implants to hold a full arch — four well-positioned ones do the job because the angled back implants maximize bone contact.
Vs. an implant overdenture: an overdenture snaps on and off for cleaning; All-on-4 is fixed — it never comes out except at the dental office. Fixed means more natural function; removable means easier home cleaning. Both are legitimate choices with different tradeoffs.
Who Is a Good Candidate
The classic candidate: someone with failing teeth throughout an arch (advanced gum disease, severe decay, broken-down dentition), or a denture wearer tired of the limitations. Good candidates generally have:
- Enough bone for four implants to achieve solid initial stability — the angled-implant design makes this possible for many patients who lack bone for individual implants everywhere
- Reasonable general health for surgery
- Willingness to follow a soft diet during healing and maintain diligent hygiene afterward
- Realistic expectations about the temporary-then-final two-phase process
Patients who were told they “don’t have enough bone for implants” should get a second opinion with a 3D scan — All-on-4 was specifically designed to work around bone limitations that rule out other approaches, often avoiding sinus lifts and extensive grafting.
Who May Not Qualify
Severe, widespread bone loss can still rule out even All-on-4 without preliminary grafting. Uncontrolled diabetes, heavy smoking, certain bone-affecting medications, and medical conditions that impair healing need individual evaluation. And bruxism (heavy grinding) must be planned for — it doesn’t disqualify you, but the final prosthesis design and a night guard account for it.
The Treatment Timeline, Step by Step
- Consultation and 3D planning. Exam, medical review, and an in-house 3D CBCT scan. Implant positions are planned digitally — precision here is what makes the surgery predictable.
- Surgery day. Remaining teeth removed if needed; implants placed under anesthesia/sedation. In most cases, a fixed temporary bridge is attached the same day — you leave with teeth.
- Healing (several months). Bone fuses to the implants while you follow a soft diet. Check visits monitor progress.
- Final prosthesis. Once integration is confirmed, detailed records are taken and your permanent bridge — refined aesthetics, optimized bite, durable materials — is crafted and fixed in place.
- Maintenance. Professional servicing on schedule, diligent home care (including cleaning under the bridge with a water flosser), and regular checkups.
Recovery: What to Expect
Surgery day itself is under anesthesia — you won’t feel it. The first week brings swelling and soreness, managed with prescribed medication; most patients return to normal routines within days. The soft diet through healing is the main lifestyle adjustment — it’s temporary and it’s what protects your investment. Follow-up visits are brief check-ins, not ordeals.
Cost Factors
All-on-4 costs more than a conventional denture and less than individual implants for every tooth — that’s the honest positioning. The fee reflects surgery, four or more implants, two prostheses (temporary and final), 3D planning, and specialist-level restoration design. Factors that move the number: whether extractions or grafting are needed, one arch versus two, and the materials chosen for the final bridge. We don’t publish fees because your cost depends on your case — at a consultation you receive the exact plan and transparent pricing before deciding anything.
The Honest Tradeoffs
- It’s surgery. Anesthesia, healing time, and post-op diet are real commitments.
- Hygiene demands are higher than for a denture — cleaning under a fixed bridge takes daily attention (a water flosser makes it routine).
- The prosthesis isn’t lifetime-guaranteed. The implants can last decades, but the bridge itself will eventually need servicing or replacement after years of function — though that’s far simpler than redoing implants.
- Not every mouth qualifies. Proper case selection protects you from an expensive disappointment.
Frequently Asked Questions
Is All-on-4 really only four implants?
Usually four per arch — sometimes five or six if anatomy or bite forces call for it. The angled back implants are the key innovation, engaging dense bone while avoiding sinuses and nerves.
Will I have teeth the day of surgery?
In most cases, yes — a fixed temporary bridge is attached the same day. You’ll follow a soft diet while the implants heal, then receive the final permanent bridge months later.
Can All-on-4 be done if I’ve worn dentures for years?
Often yes. Long-term denture wear causes bone loss, but the angled-implant design works with less bone than individual implants need. A 3D scan determines your specific situation.
How do I clean under a fixed All-on-4 bridge?
Daily water flosser use under the prosthesis, plus brushing — your hygienist will demonstrate the technique. Periodic professional servicing (where the bridge may be removed and cleaned) is scheduled by your dentist.
How long does All-on-4 last?
The implants can last decades with good care. The prosthetic bridge is durable but will eventually need servicing or replacement after years of chewing — without redoing the implants.
Why see a prosthodontist for All-on-4?
It’s the most restoration-driven implant procedure: full-arch bite design, aesthetics, and long-term prosthetic planning. A prosthodontist’s specialty training is specifically in replacing teeth and designing bites — this is the core of the specialty.
