Abstract: Objective This study investigates the chin morphology characteristics in female adolescents with different vertical skeletal craniofacial patterns to provide reference for the early design of chin morphology. Methods Ninety female adolescents were selected randomly. They were divided into the following three groups according to mandibular plane angle: high angle group, average angle group, and low angle group. Cepholagrams were obtained, and cepholametrics was employed. Data were analyzed by SPSS 13.0. Results Statistically significant differences were found in the chin angle, chin curvature, mandibular chin angle, anterior alveolar height, depth of the mentolabial sulcus, thickness of the soft tissue of the chin, UL-Ep, and LL-Ep(P<0.05). In the high angle group, the chin curvature, anterior alveolar height, mandibular chin angle, UL-Ep, and LL-Ep were maximum; and the chin angle, depth of the mentolabial sulcus, and thickness of the soft tissue of the chin were minimal. Conclusion Differences in chin morphology characteristics were found in female adolescents with different vertical skeletal craniofacial pattern. This study should be taken as a reference in orthodontics.
