Influence of condylar guide inclination on condylar positioning during clenching.

The relationship between the steepness of the articular eminence and the condylar positioning during clenching was investigated in 19 volunteers with natural dentitions. The condylar positioning during maximal voluntary contraction was measured using a mandibular movement analysis system with six degrees of freedom. The sagittal condylar guide inclination was also measured using the same apparatus.

[Relationship between condylar displacement during clenching and condylar guide inclination].

Purpose: Many studies have reported the relationship between facial morphology and stomatognathic functions. The steepness of the articular eminence is an important morphological factor to determine the mandibular movement or mandibular positioning. The present study analyzed the relationship between the condylar displacement during clenching and the condylar guide inclination related to simulated loss of posterior occlusal support.
