Once you've decided implants are the way to replace a full arch, there's a second choice: a fixed All-on-4 bridge, or snap-in (implant-supported) dentures. Both use implants for stability — the difference is whether your teeth stay in permanently or clip in and out. (New to all this? Start with our All-on-4 guide.)
How snap-in dentures work
Snap-in dentures (also called implant-supported overdentures) attach to a small number of implants — often two to four — using clips or attachments. They're far more stable than traditional dentures, but you still remove them to clean and at night.
How All-on-4 works
All-on-4 is a fixed full-arch bridge anchored to four implants. It stays in your mouth permanently; only your dentist removes it for maintenance, and you clean it in place, like natural teeth.
The core difference: removable vs. fixed
That's really the heart of it. Snap-in dentures give you implant-level stability with the option to take them out. All-on-4 gives you the closest feel to natural teeth and nothing to remove — at a higher investment, since it's a more involved restoration.
Comparing the two
- Stability: Both are dramatically more stable than traditional dentures; fixed All-on-4 is the most secure.
- Maintenance: Snap-in comes out for daily cleaning; All-on-4 is cleaned in place.
- Implants needed: Snap-in often uses fewer implants; All-on-4 uses four to support a full fixed bridge.
- Feel: Many patients say fixed teeth feel most like their own.
- Investment: Snap-in is generally the more budget-friendly implant option; All-on-4 is a larger investment.
Which is right for you?
It comes down to your priorities — budget, how much you value a fixed solution, your bone, and your daily preferences. We provide both options, which means our recommendation is based on what fits you, not on what we happen to offer. If you've been told you may not have enough bone for implants at all, read this first — there are often options.
