Implant-Supported Dentures
A denture that snaps onto implants instead of resting on the gum — removable, but it stays put.
Overview
An implant-supported denture, also called an overdenture, is a full denture that clips onto two or more implants placed in the jaw. You still take it out to clean, but it no longer relies on suction and gum contact to stay in — so it does not rock while you eat and does not need adhesive. For patients who have worn a conventional lower denture, this is usually the single biggest change in comfort available, because a lower denture has the least natural stability.
It sits between two other options in both cost and function: more stable and more expensive than a conventional denture, less expensive but also less permanent than a fixed All-on-4 arch that never comes out. Because the implants transmit chewing force into the bone, an overdenture also slows the bone loss that makes long-worn dentures progressively looser. Denvida plans the implant positions on a CBCT scan and shows all three options with their real numbers at the free consultation.
Options & Types
Two-implant overdenture (lower)
The most common starting point for a loose lower denture — two implants add retention at the lowest cost.
Four-implant overdenture
Four implants spread the load and reduce rocking further — often chosen for the upper arch, which needs more support.
Fixed full arch instead (All-on-4)
If you would rather never remove it, a fixed full-arch bridge on four implants is the alternative — higher cost, closest to natural teeth.
The Process
- 1
Free consult + 3D scan
A CBCT scan shows how much bone remains after years of denture wear and how many implants the arch can support.
- 2
Implant placement
Two to four implants are placed under local anesthesia using the guided plan; your existing denture can often be adapted as a temporary.
- 3
Healing
The implants fuse with the bone over 3–6 months. You keep wearing the adapted denture during this time.
- 4
Attachments & final denture
Retentive attachments go onto the implants and the denture is fitted to snap onto them, then the bite is balanced.
Cost & Financing
| Procedure | Bay Area range | Denvida |
|---|---|---|
| Implant overdenture (per arch) | $6,000–$15,000 | written estimate |
| Conventional denture, for comparison | $1,000–$3,000 | written estimate |
| Fixed All-on-4 arch, for comparison | $25,000–$35,000 | written estimate |
Ranges are Bay Area market references, not quotes, and vary mainly with the number of implants and whether grafting is needed. Denvida gives a detailed written estimate before treatment and is in-network with Delta Dental & Cigna; financing available.
Frequently Asked Questions
How much do implant-supported dentures cost in the Bay Area?
An implant overdenture typically runs $6,000–$15,000 per arch at Bay Area market rates, depending mainly on how many implants are used and whether bone grafting is needed. That sits between a conventional denture ($1,000–$3,000) and a fixed All-on-4 arch ($25,000–$35,000). Denvida gives a free consultation with a 3D scan and a written estimate.
What is the difference between implant-supported dentures and All-on-4?
An implant-supported denture snaps onto the implants and you take it out to clean; All-on-4 is a fixed bridge on four implants that only the dentist removes. All-on-4 feels closest to natural teeth and needs no daily removal, but costs considerably more and requires enough bone for angled implants. An overdenture is the lower-cost route to a denture that no longer slips.
How many implants are needed for a denture?
Two implants are usually enough to hold a lower denture securely, while an upper denture generally needs four because the upper jaw has softer bone and a larger surface. The exact number depends on your remaining bone volume, which a CBCT scan at the free consultation measures directly.
Can my existing denture be converted to snap onto implants?
Sometimes. If your current denture fits well and the acrylic and teeth are in good condition, attachments can often be added to it after the implants heal, which lowers the cost. If it is worn, badly fitting or the bite has changed, a new denture built for the implant positions gives a better long-term result. This is assessed at the consultation.
