OBJECTIVE: The aim: There is no information on the esthetic features of the face, which are typical of the patients with late mixed occlusion with maxillodental anomalies of Angle's class II1 depending on the types of mandible growth in domestic and foreign literature. To study the esthetic peculiarities in the face profile, which are typical of the patients aged 10-13 with maxillodental anomalies of Angle's class II1 with different types of mandible growth.
PATIENTS AND METHODS: Materials and methods: 55 patients aged 10-13 with maxillodental anomalies of Angle's class II1 were examined. Teenagers were divided into five groups depending on the type of mandible growth. 82 photostatic images in profile were analyzed. Soft tissue analysis was performed using the Viasis method.
RESULTS: Results: Face profile was studied based on the following indicators: convexity angle of the face profile Viazis (<V), profile angle by Schwarz (<T), the angle of the face profile shape (<gl-UL -pg), Th-me / NoV angle, nasolabial angle, labial angle (<L), mentolabial angle.
CONCLUSION: Conclusions: Photometric study in 55 patients aged 10-13 with maxillodental anomalies of Angle's class I and analysis of the results depending on the types of mandible growth prove the presence of a retrogenic type of the lower third of the face, convex shape of the profile, the development of posterior bite of varying severity. All patients were reported to have changes in the indicators of the lips position and non-harmonious development of their faces. The greatest esthetic changes were reported in the group of patients with a component of horizontal type of mandible growth.
