The relationship between lateral border movements of the mandible and the determinants of occlusion.
Border movements of the mandible were measured with a jaw movement analyzer in nine subjects. This instrument records movement with 6 degrees of freedom and has the ability to accurately and linearly record the full range of jaw movement. The result of this study showed a relationship between the presence of balancing-side molar contacts and restricted contralateral jaw border movements. This restriction is probably due to aberrant external pterygoid muscle activity.
