[Morphology of the laterotrusive paths in dentitions with normal function].
The occlusal surface of the posterior teeth of 20 subjects with class-I-occlusion were analysed by means of an electronic profilograph in laterotrusion. Each of the curvatures recorded was defined by an approximated radius as well as its angle to the occlusal plane. The software used was specifically developed to suit this particular purpose. The data showed characteristic regularities. The results indicate that the average radius of the canine is longer than that of the molars. An alternating increasing and decreasing tendency of the angles to the occlusal plane was observed. The results suggest that the concept of canine-protected occlusion may be strengthened by the fact that there is a genetic determination of the canine dominance.
