[Characteristics of occlusal plane in patients with class iii malocclusion].

Occlusive plane of teeth is the line of teeth which connects upper and lower teeth. Direction and level of occlusive plane determines normal function of dento-skeletal system and is very important for facial aesthetics. The aim of our study was to determine position of occlusive plane in relation to alveolar bases of upper and lower jaws in patients with class III malocclusion, also to analyze characteristics of occlusive plane changes during the growth. After analysis of the results of our study, we can conclude that during the growth and development of facial skeleton occlusive plane of examined patients with class III malocclusion rotates counter-clockwise, due to decrease of vertical dimension (height) of dento-alveolar segment in lower molar area.
