ABSTRACT
The aim of the investigation was to determine the orientation of occlusal plane by morphometric parameters of cranio-facial complex, to study the morphology of HIP-plane and correlation relations with cerebral and facial cranium measurements.Materials and Methods. The crania with mandibles were fixed in craniostat, and measurements were made using thickness and sliding calipers, vernier calipers of various designs. We took scaled photos of all crania using support stand, with equal approximation, in three views (coronal view, lateral view, skull base view). Digital material was computer processed.Results. We developed craniometric technique to analyze the morphology and topography of HIP plane (Hamulus–Incisive Papilla) . Transverse facial size was found to be 1.2 times less compared to the transverse cranial diameter, and transverse facial size between zy–zy (zygion) points — 2.5 times larger than the distance between H (hamular notcher) points right and left. Facial n–gn (nasion–gnation) size was found to have medium correlation relationship with the altitude of HIP triangle. Anthropometric ipp (incisive papilla posterior) point appeared to be by 10% more stable than ip (incisive papilla) point. Therefore, for HIP-plane determination we recommend using not incisive papiila (ip), but the point, which is 3 mm distal (ipp point) and located on distal bony edge of the incisive canal opening. The analysis of the lateral view of cranium showed the relations of occlusal plane of maxilla and HIP-plane to be characterized by strong positive correlation. The inclination angle of Camper’s plane to HIP did not exceed 6°. HIP-plane appeared to be more stable to determine the orientation of maxillary occlusal plane position.
