Abstract
The average amount of disocclusion on working side during lateral movement of subjects with normal dentition and free of TMD, was 0.41±0.27mm, measured on the study models mounted on a semi-adjustable articulator, using a leaf gauge.
The frequency of occurence for canine guided occlusion (mutually protected occlusion) is larger than that for group functioned occlusion by about 10 times (50 samples vs 4 samples) .
The fact that there are distinctly significant difference between the average amounts of disocclusion during the protrusive movement and on the nonworking side lateral movement and the one on the working side lateral movement, indicates that the proper amounts of disocclusion is necessary for establishing sound occlusion.
