Abstract
The theoretical equation concerning the direction of tooth guidance, which was statistically based on the direction of balancing condylar path, was applied to three subjects and their stomatognathic functions were discussed. The stomatognathic functions were evaluated by clinical symptoms, mandibular movements, and muscle activities as parameters.
The conclusions were as follows:
1. Depending on the direction of tooth guidance calculated from the theoretical equation, that of subjects should be gentler or steeper.
2. In reconstructing the direction of tooth guidance:
1) Some clinical symptoms were alleviated.
2) The mandible was smoothly moved, not even affecting the condylar path.
3) The leftand right masseter muscles, anterior temporal muscles, and posterior temporal muscles showed nearly normal activities.
3. The meaning of theoretical equationin stomatognathic function became obvious.
