There are two types of dentures: partial dentures and full dentures.
A full denture is used when there are no teeth in the top or bottom arch. It is called a full denture since it fully replaces all the teeth in one arch. The advantage of a full denture is it replaces all the teeth at once when all the teeth are really broken down or have a lot of bone loss. Another advantage for a full denture is that the esthetics are real good. Since the dentist is replacing all the teeth at one time, he can make the teeth look as white and straight as the patient desires.
The big disadvantage of a full denture is that it often has trouble staying in place. A full denture relies on suction to keep it in place. This works great if the ridge on which the denture is sitting is very large and firm. When teeth have been gone for a long time, the ridge starts to shrink in size. This causes the denture to have less retention and move around with eating and talking. A full denture is never as good as a full set of healthy teeth.
A treatment option for those who have trouble with a full denture is to have implants placed in the jawbone that can be used as anchors. The denture has small snaps that attach to the implants. While this will not make a full denture feel like natural teeth, it will definitely help keep the denture from moving around too much. Give us a call to discuss what options are best for you.
