In short: For an edentulous jaw there are three routes: a conventional full denture, a removable denture retained on a few implants, and a fixed bridge on several implants. The difference lies mainly in how securely it holds when eating and speaking, and in how much further the jawbone breaks down. What is possible is decided by the bone available.
Losing all the teeth in one jaw changes more than appearance. It changes what you can eat, how you speak and how confident you feel when you laugh. That is why choosing the restoration is one of the most consequential decisions in dentistry — and one where often only a single option gets mentioned.
The three routes
- Full denture: rests on the jaw and holds by suction. No surgery, lowest cost, possible at any time. Drawbacks: limited hold especially in the lower jaw, reduced chewing force, a covered palate and therefore altered taste, and regular adjustment because the bone underneath continues to shrink.
- Implant-retained denture: a few implants act as anchor points, the denture attaches to them and is taken out for cleaning. Considerably more hold at manageable effort — for many patients the best compromise.
- Fixed bridge on implants: often referred to as an All-on-X concept. Several implants carry a bridge that stays in the mouth. Chewing force and stability come closest to natural teeth and the palate stays free. Highest surgical effort and highest cost.
Why the bone makes the real decision
An edentulous jaw breaks down continuously over the years because the load from tooth roots is missing. Someone who has worn a full denture for a long time often has less bone than someone who implants soon after tooth loss. That is not a refusal — bone can in many cases be built up, and there are implant positions that carry load even with less volume. But it does mean more effort, more time, higher cost. Conversely, an important side effect of implants is that they load the bone again and slow the breakdown.
What differs in daily life
The practical questions are rarely the medical ones. Can you bite into an apple? Does anything slip when you speak in a group? Do you have to take something out at night? Do others notice? With a fixed restoration the answers are usually yes, no, no, no — in exchange, cleaning is more demanding and requires disciplined use of special brushes plus regular professional aftercare.
The sequence in stages
It begins with three-dimensional imaging of the jaw and digital planning. Then come the surgical procedure, a healing phase and the final restoration. You are not without teeth during that time — a provisional restoration is fitted, in some cases already a fixed immediate one. How long the whole treatment takes depends mainly on whether bone has to be built up.
In consultation we go through all three routes with their respective drawbacks, and you receive a written treatment and cost plan including the alternatives — even where one of them is considerably cheaper.
Frequently asked questions
How many implants does an edentulous jaw need?
For a removable denture with retention, a few are often enough in the lower jaw. A fixed bridge needs more, typically four to six per jaw, depending on bone volume and planned load.
Is this possible with severe bone loss?
Often yes — through bone grafting or through special implant positions that use remaining stable bone areas. The planning shows what will carry load.
Will I be without teeth in between?
No. A provisional restoration is worn throughout, in suitable cases a fixed immediate restoration directly after the procedure.
What does German insurance cover?
Patients with statutory insurance receive a finding-based fixed subsidy oriented on the standard case — the full denture. That amount also applies to a higher-grade restoration; you carry the difference.
