01
A single fixed bridge
One continuous prosthesis screw-retained onto five posts. Removable only by the clinician for service.
A Patient Guide · Updated May 2026
Not four because the brochure said four. Not six because more sounds safer. Five when the scan, the bite, and the bone agree.

What All-on-5 is
01
One continuous prosthesis screw-retained onto five posts. Removable only by the clinician for service.
02
Placement decided from CBCT and a wax-up. The fifth site exists because the records earned it.
03
Surgery and provisional first; healing; then the definitive bridge once integration is confirmed.
Why five — honestly
A proven minimum when bone is good, the bite is balanced, and the arch is not wide. Two angled posterior implants extend the support without invading the sinus.
The middle ground when the scan shows the four-post span is too long for the bite, but a sixth implant has nowhere clean to sit. Common on upper arches and wider arches.
Reserved for wider arches, heavier bites, or cases where two extra anterior implants meaningfully change the prosthetic design — not as a default upgrade.
Candidacy
The process
Step 01
Medical history, periodontal charting, CBCT scan, intraoral scan, photographs and a written diagnosis.
Visit 01 · Day 1
Step 02
A diagnostic wax-up confirms the bite, the bridge shape and the five implant positions before surgery is scheduled.
Before surgery
Step 03
Five implants placed under guided protocol. A provisional bridge is loaded only when stability allows.
Visit 01 · Day 2–4
Step 04
48-hour review, two-week review, then monthly remote check-ins while osseointegration progresses.
~4 months
Step 05
Once integration is confirmed, the definitive bridge is fabricated, fitted and torqued. Maintenance schedule begins.

Materials & longevity
PMMA
The bridge worn during healing. Reliable, repairable, and never the final answer. Expect 12–24 months of service.
Zr
Monolithic or layered zirconia: the most durable definitive choice. Strong, biocompatible, and tolerates heavier bites with predictable wear.
PFM
Porcelain on a metal substructure. Excellent aesthetics and proven longevity when the bite is balanced and chipping risk is managed.
A premium-quality All-on-5 case typically pairs a PMMA provisional during healing with a zirconia or porcelain-fused bridge at delivery. Anyone offering a single price without naming both materials is quoting two different cases as if they were one.
What it costs — and why
When two quotes are far apart, one of these five drivers is usually doing the work. A premium plan will be transparent about each. A budget plan will be silent on most.
Premium implant systems with documented long-term data and digitally guided placement cost more than commodity systems placed freehand — and they should.
A definitive zirconia or porcelain-fused bridge is a different product from a long-worn acrylic provisional. The price gap is real and earned.
CBCT, intraoral scans, a wax-up and a written plan add cost up front and remove cost from the next decade. Cases without them tend to be remade.
Grafting or sinus elevation is sometimes the only way to make the fifth site usable. It is a separate line item and a separate timeline.
A serious quote names the maintenance schedule and the warranty terms in writing. A silent quote externalises both onto you.
Before you pay
The reason should reference your CBCT, your bite, and your bone — not a price list or a package name.
A brand and model with documented long-term data, not "premium European" as a category.
Provisional and definitive listed as two separate items with two separate prices.
A plan you can read, dated and signed, before any surgical decision is finalised.
Same-day loading only if stability is confirmed, with a written "if/then" for the alternative.
Hygiene cadence, yearly review, and what is included vs charged separately.
What is covered, for how long, and under what conditions — in the contract, not the brochure.
Named clinician, credentials, and the same name still present on the day.
Common questions
Because the scan may show a four-post bridge leaves too much span or too little support — especially in the upper arch. The fifth implant is added when records make the case for it, not by default.
No. The provisional is loaded only when implants reach safe stability during surgery. If they do not, the provisional waits — and that is the safer outcome, not a worse one.
No. It is better only when the added site improves support without creating a cleaning or surgical problem. Otherwise four is the cleaner plan.
Usually, but the price gap should reflect one fewer implant and abutment — not an inferior material or a shorter warranty. Compare the line items, not just the totals.
Implants are designed to last decades when oral hygiene and maintenance reviews are honoured. The bridge material on top has a separate lifespan — porcelain-zirconia bridges typically outlast acrylic provisionals by years.
Two is the standard pattern: one for records, surgery and the provisional bridge; a second after osseointegration for the definitive bridge. A single-trip case exists, but it is the exception and it should be justified in writing.
