[The relationship between protrusive condylar and incisal path].

The protrusive condylar and incisal sagittal paths from 70 normal subjects were studied with MT1602. The results showed that the correlation rate between the inclination of condylar and incisal guidance was 0.49 (P < 0.01). But the results from multivariate analysis showed the primary affecting factor on condylar guidance was the face angle, whilst the incisal guidance was mainly influenced by the upper and lower front teeth relationship.
