If the posterior molars are missing and the row of teeth is shortened in the forward direction, then one speaks of a “free-end” situation. A conventional bridge can no longer be anchored at the end of the jaw since there is no longer a tooth that could serve as a bridge pillar. The optimal solution is the restoration with single dental implants, or alternatively an implant-supported bridge, as with larger tooth gaps. With implants, the interfering metal stirrups of a staple prosthesis are done away with and daily care is much more uncomplicated. The most important advantage, however, is its function – a dental prosthesis on implants has no effect on the function of naturally healthy teeth. Even with an implant bridging solution, absolute stability is ensured.
Even when a person is fully edentulous, single implants or a fixed bridge on multiple implants is possible – even with low bone mass. In order to achieve sufficient stability, four implants are usually required in the lower jaw. The upper jaw has a softer bone substance, which is why often more implants (5-6) have to be placed here. In the case of people with a lack of teeth, using implants as a support can basically be carried out in two ways: with removable or with fixed dentures. In the first variant, the prosthesis is fastened, for example, to a so-called bridge. The dental implants are connected to each other by means of a bridge which provides a secure support for the prosthesis.
When it comes to fixed dentures on implants, the entire series of teeth is fixed on the implants and remains permanently in the jaw. This is usually possible for those who are completely toothless. Depending on the person’s jaw and bone situation, four implants per jaw is sufficient. Firm or removable: With both solutions, the implants provide the dentures with a secure and stable support. Various methods are available for the realization of implant solutions. In addition to safe chewing and speaking as well as flawless aesthetics, implants have a positive effect in the long term. The most important are the preservation of the jaw bone due to the persisting tensile force on the jaw as well as the protection of healthy neighboring teeth.
