Disocclusion is a common sense in today's prosthetic dentistry. The amount of disocclusion based on quantitative data is not known. Impressions of 25 male subjects with normal dentition and free of TMD were taken using silicone bite material during protrusive and lateral movements. Cutting them through mesio-buccal cusp tip of the lower first molar, distances between them and occlusal surfaces of the opposing teeth, were measured.
The results showed that the average amounts of disocclusion are about 1 mm during protrusive movement and on nonworking side during lateral movement, and about 0.5mm on working side during lateral movement. Standard deviations were 0.3mm-0.6mm.
