[Do pin guides have any effect on the limits of mandibular movements?].

In the Denar and Stuart pantographs, the movement limits in one subject using 12 different tracing pin guides were recorded and evaluated. No changes in the movement of the terminal hinge axis were found. By means of a registration device fixed to the Denar articulator it was found that the tracing pin guide has an influence on the inclination of the functional facets of the teeth: the flatter or more convex the tracing pin guide, the flatter the occlusal structures.
