Gnathosonic monitoring of occlusion of complete and partial dentures

The durations of occlusal sounds of edentulous patients wearing complete dentures and of partially edentulous patients with and without partial dentures were measured. In general the durations of the sounds decreased after adjustment of occlusion and after periods of wearing the dentures, but in a cross-section study of sound duration of old complete dentures (mode 16 years) an increased sound duration was observed.
