[The correlation of the occlusal plane and the Frankfurt Horizontal parameters with the morphological and functional indices of the maxillofacial area in physiological dentition relationships].
Anthropometric, functional, and teleroentgenographic examinations were carried out in 26 subjects aged 20-27 years with functional occlusion. Correlation of occlusion plane direction (OcP) with respect to the Frankfurt horizontal line (FH) and the dental, gnathic, and soft tissue parameters of the head and maxillofacial muscular functions was studied. The angle formed by the Frankfurt horizontal line and occlusion plate (FH-OcP) depends on the anthropometric angular and linear osseous parameters of the facial skull and soft tissue parameters of the face and with the functional status and coordination activity of maxillofacial muscles antagonists and synergists. It is noteworthy that the FH-OcP angle depends on the level of disposition and, which is still more important, on the direction of occlusion surface, and evaluation of individual OcP is the key to restoration of the morphofunctional harmony of the maxillofacial system during orthodontic treatment.
