The situation of occlusal contacts is closely related to the masticatory function of edenturous patients. So there are many studies of occlusal contacts for the purpose of explicating masticatory function in edenturous patients. However, at the time of investigation of occlusal contact, they are not considered the interocclusal distance and occlusal position which have an influence on the masticatoy efficiency.
In this longitudinal study, the author measured the areas of occlusal contact in complete denture using a acrylic resin teeth at various occlusal distances and occlusal positions from a insertion of dentures to one year later. The conclusions are as follows:
1. In all occlusal positions, the areas of occlusal contact are about the same in early days.Afterwards, they increase gradually and reach maximum at six months later, and decrease one year later.
2. In all occlusal positions, measurement time and interocclusal distances influence areas of occlusal contacts significantly (α<0.05).
3. As a result of this study, in case of complete denture prosthesis using a acrylic resin teeth, it is clinically suggested that their teeth should be replaced with new teeth or reconstructed ith hard cold-curing resin about six months later.
