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.
该分析的目的是确定具有不同骨骼颌骨关系的个体的直面型、凹面型和凸面型的存在情况。根据G. 阿内特和R. 伯格曼提出的面部角度，为每个人确定一种特定的面型类型。对240名12至14岁、根据ANB角（施泰纳）值判定为I类、II/1类、II/2类和III类骨骼颌骨关系的个体进行了头颅侧位X线片分析。按照伯格曼和阿内特的方法对这些人的软组织面型进行了分析。根据所得结果，大多数人呈现凸面型（51.2%），直面型占32.5%，而凹面型占16.3%。凸面型在II/1类个体中占主导（83.3%），其次是II/2类个体（64.5%）和I类个体（55.9%），而凹面型主要是III类个体的特征（59.3%）。直面型在I类和III类骨骼颌骨关系的个体中出现的比例相同（40.7%），在II/1类个体中出现的比例最低（16.7%）。与男性个体（33.3%）相比，女性个体中规则面型的数量是男性的两倍（66.7%）。I类和II/2类个体中存在所有三种面型类型，II/1类个体中存在直面型和凸面型，III类个体中存在直面型和凹面型，这表明这些面型是牙骨骼颌骨关系以及其他一些因素作用的结果。只有完整的头颅侧位X线片分析才能提供充分的治疗计划，从而实现咬合关系的协调并获得良好的美学效果。
