Abstract

The purpose of this study was to examine the effects of the direction of lateral tooth guidance on jaw movement. Nine healthy adult volunteers (10 experimental sides) with natural dentition were the subjects. Lateral excursion was recorded by using a six-degree-of-freedom jaw motion analyzing system while the subjects wore a maxillary acrylic resin splint. Six different acrylic resin guidances were attached to the canine region of this splint. These guidances included M typeo (latero protrusive) and D type (latero retrusive) with 15, 30, and 45 degrees of inclination.<BR>It was found that D type lateral tooth guidance led a more posterior pathway for the incisal point and working condylar point than M type lateral tooth guidance at each inclination. The results showed that Dtype guidance could decrease posterior condylar space during bruxism and cause overload in temporomandibular joint.
