Analysis of working-side occlusal contacts.

Bilateral interocclusal registrations were made of two working-side mandibular positions of 45 healthy young adults with morphologically good occlusions. The occlusal contacts were analyzed according to frequency and location. A large number of subjects presented unclassified patterns of articulations. In the group with known occlusal schemes, more individuals had "canine guidance" on the left side, whereas the most frequent pattern on the right side was "partial group function."
