Soft tissue profile changes during treatment of patients with class II malocclusion

Introduction/Objective. The class II malocclusion results in disbalanced facial harmony, primarily noticeable the profile and lower third. Aside from skeletal evaluation, orthodontic diagnosis treatment planning should include soft tissue analysis. aim of study was to identify outcomes II, division 1 patients determine if these changes are related different protocols. Methods. first group non-extraction (25 patients) initially treated with Herbst appliance, second four premolars extraction a multibracket appliance. patients? cephalograms pre- post-treatment photographs were used. Results. improvement evident decrease nasomental angle, angle representing projection upper lip chin, as well angle. In group, nasolabial showed significant increase. Soft variables differences between groups: total or convexity including nose presenting chin. Conclusion. without extractions convex favorable third face.
