Characteristics of different face types with mesial and orthognathic bites

To increase the quality of orthodontic diagnosis, A.M. Schwartz's face types were researched using a modifi ed version of Y.M. Malygin's technique. The collected data in the mesial occlusion are compared to the norm data. In general, Schwarz's prediction that the dimensions of the face and inclination angles will remain stable within 85° is confi rmed. However, the spread of these values in our material was wider, with an average of 8513,74°; however, this has no effect on the classifi cation of face types in mesial occlusion.

Out of the nine face types, medium face types (4,5,6) had the highest rate of orthognathic occlusion (52.38%). And with a mesial blockage, the posterior kinds of the face (43.1%) play this duty (7,8,9), indicating that there is a dento-alveolar type of pathology. Regardless of the position of the upper jaw in the facial space, there is a tendency to retroinclination of the gnathic section of the facial part of the skull (3,6,9 types - 24.14%) with mesial occlusion; this is more than fi ve times normal. This fact implies forward and upward rotation of the gnathic portion, which can result in forward and to the side displacement of the lower jaw in the case of a mesial occlusion.
