Analysis of condylar path inclination and incisal guidance

A sample of 50 stomatognathic system dysfunction syndrome patients were analyzed in terms of the anterior discluding path in relation to the condylar path inclination, the condylar-incisal and incisal-APo angles, and the distance in millimeters between the latter and the interincisor angle employing cephalometric outlining. The present results reveal that the difference between the inclination of the incisal and condylar trajectories is smaller than that reported by other authors for normal occlusion samples. The lower incisor lies beyond the APo line in 25% of the sample, not conforming to the accepted standards. There was no significant difference between the present ratios and those reported by other authors for normal samples.
