Abstract
It is conventional practice to fit a full denture in patient who,as a result to Periodontitis or other factors, have become completely edentulous. However, in the absence of any natural teeth, the occlusion changes from being tooth supported to a situation where it is supported exclusively by the oral mucosa. At this stage the dentist has no reference point as to the shape, size, color, of the original dentition, and can only images what they looked like. In addition ,the original maxilla-mandibular relationship is lost. With a full denture there are a variety of ways of diagnosing the optimal mandibular position.However, because the mucosa is not stable, and there is no fixed position ,these techniques are very difficult, and depend very much on the skill of the individual dentist, which is less than an ideal situation.
Recently, by using implants and a bone anchored bridge for edentulous patients, we are in a position to provide bone supported occlusion,
In this paper, we will describe how to decide the mandibular position and tooth form, when using bone anchored, and rigid prosthodontics.
