The four options compared
| Regular denture | Implant overdenture (snap-on) | Fixed full arch (All-on-4 or All-on-6) | Individual implants | |
|---|---|---|---|---|
| Implants | None | 2–4 | 4–6 | One per tooth or bridge |
| Removable | Yes | Yes, by you | No | No |
| Movement when eating | Can move, especially lower | Stable | None | None |
| Covers the palate | Upper usually does | Often not needed | No | No |
| Surgery | No | Yes, minor | Yes | Yes |
| Relative cost | Lowest | Middle | Higher | Highest for a full mouth |
Pros and cons, briefly
Regular dentures. No surgery, quick and the lowest cost. They can move, especially in the lower jaw, can make some foods hard to chew, and need relining as the gums shrink.
Implant overdentures. A big step up in stability for a modest number of implants. The 2002 McGill consensus statement recommended two-implant overdentures as the first-choice standard for people with no lower teeth. You still take them out to clean them, and the clips are replaced from time to time.
Fixed full-arch teeth. They feel the most like natural teeth and are never taken out. They need more implants, more planning and a higher budget, and cleaning under them takes a little practice.
Individual implants. Best for one or a few missing teeth. For a whole jaw, a fixed arch on four to six implants usually does the same job for less.
Who suits what
- Healthy, with good bone, wants fixed teeth: full-mouth implants.
- Loose lower denture, wants stability without a big budget: implant overdenture.
- Severe bone loss: basal or zygomatic implants may avoid grafting.
- Surgery not advisable, or teeth needed quickly: a well-made complete denture, which can be converted later.

Questions patients ask us
Are implants better than dentures?
For chewing and stability, yes. Implant-held teeth don't slip, and fixed implant teeth feel closest to natural teeth. Dentures are still a good choice when surgery isn't advisable or the budget is limited, and an existing denture can often be converted to clip onto implants later.
What are snap-on dentures?
A denture that clips onto two to four implants. You remove it to clean it, but it doesn't move while you eat or speak. For the lower jaw, a two-implant overdenture is widely considered the minimum standard of care.
Are implants worth it for older people?
Age alone isn't a barrier. What matters is general health, bone and the ability to keep the implants clean. Many people in their seventies and eighties do very well with implant overdentures.
How long do dentures last compared with implants?
Dentures are usually relined or remade every five to ten years as the gums and bone change. The implants themselves often last decades; the teeth on them wear and are renewed over time.
Can I change from dentures to implants later?
Usually, yes. The sooner it's done, the more bone there tends to be, because bone under a denture shrinks gradually.
