Effects of changes in articulator settings on generated occlusal tracings. Part I: Condylar inclination and progressive side shift settings.
An occlusal scribing device attached to a fully adjustable articulator was used to generate occlusal tracings. The tracings were analyzed to determine the effect changes in progressive side shift and condylar inclination settings had on molar occlusal morphology. The progressive side shift adjustment affected the cusp height and ridge and groove position, primarily in the nonworking excursion. The condylar inclination adjustment affected the cusp heights in the protrusive and nonworking excursion without affecting the working excursion.
