An implant overdenture is a removable denture that locks onto 2–4 implants with attachments (locators) or a bar. It does not move when you eat or speak, needs no adhesive, and comes out at night for cleaning. It costs less than a fixed bridge and needs fewer implants and less bone — so it is sometimes the right solution even when a fixed bridge is technically possible.
Overdenture or fixed bridge?
| Implant overdenture | Fixed bridge (All-on-4/6) | |
|---|---|---|
| Implants | 2–4 | 4–6 |
| Removable for cleaning | Yes | No — cleaned in the mouth |
| Feel | Very good; covers part of the palate (upper) | Closest to natural teeth |
| Lip and cheek support | Very good (denture flanges) | Depends on bridge design |
| Cost | Lower | Higher |
| Maintenance | Attachment inserts replaced every 1–2 years | Professional cleaning and a yearly check-up |
Who it especially suits
- People who already have a full denture that works but is not stable — especially in the lower jaw
- When budget or bone volume do not allow a fixed bridge
- When significant lip and cheek support is needed (a “sunken” face)
- People who prefer to take it out and clean it
The process
Two implants in the lower jaw (or four in the upper) are placed through a surgical guide. Sometimes the existing denture can be adapted the same day with temporary attachments; usually we wait 2–3 months and then fit the final attachments or make a new denture. Dr. Koter performs both the implant surgery and the denture.
Frequently asked questions
Implant overdenture or fixed bridge — which is better?
A fixed bridge feels closest to natural teeth. An implant overdenture costs less, needs fewer implants and less bone, supports the lips well and comes out for cleaning. For many people it is the right solution. We decide together based on the mouth, habits and budget.
Zirconia or porcelain?
Monolithic zirconia — the strongest, for molars and bridges. Porcelain on zirconia — the most aesthetic, for the smile zone. E.max — for single front crowns. Usually we combine by area.
How long does full-mouth rehabilitation take?
Without implants — a few weeks. With implants — 4–9 months, and with bone grafts up to a year. Throughout, you have functioning provisional teeth.
My teeth are worn from grinding. What can be done?
A rehabilitation that restores bite height and tooth length — crowns or veneers — together with a night guard that protects the result. Everything is tested in provisionals before the permanent restoration.
