title: [Profile types in relation to facial angle in different skeletal jaw relationships].
abstract: The aim of the analysis was to determine the presence of straight, concave and convex profiles of individuals, who have different skeletal jaw relationships. A particular profile type was determined in each person on the basis of facial angle proposed by G. Arnett and R. Bergman. The analysis of lateral cephalometric headfilm was done in 240 individuals 12-14 years old, with skeletal jaw relationship of Class I, II/1, II/2 and III according to the values of ANB angle (Steiner). Soft tissue profile in those persons where analysed according to Bergman's and Arnett's method. According to the obtained results, the majority of persons had convex profile (51.2%), straight profile was present in 32.5%, while concave profile was present in 16.3%. Convex profile is dominant in individuals with Class II/1 (83.3%), then in individuals with Class II/2 (64.5%) and Class I (55.9%), whereas the concave profile was mainly characteristic of individuals with Class III (59.3%). Straight profiles were equally present in individuals with skeletal jaw relationship of Class I and III (40.7%) and the least present in individuals with Class II/I (16.7%). The number of regular profiles was doubly greater in female individuals (66.7%) in comparison with male ones (33.3%). The presence of all 3 profile types in individuals with Class I and Class II/2, straight and convex profiles in individuals with Class II/1, and straight and concave profiles in individuals with Class III indicated that these profiles are the result of the effect of dentoskeletal jaw relationship as well as some other factors. Only the complete profile cephalometric analysis may provide an adequate treatment planing that leads to harmonization of occlusal relationships and good aesthetic result.
