Resumen

XUAN, Jing et al. Morphological Characteristics of Soft Tissue Profile of Angle’s Class II Division I Malocclusion before and after Orthodontic Treatment. Int. J. Morphol. [online]. 2018, vol.36, n.1, pp.26-30. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022018000100026.

By analysing cephalometrics before and after the treatment of Angle’s class II division 1 malocclusion, soft tissue profile changes were observed, and to explore whether there was a correlation between the change of posterior occlusal plane (OP-P) and soft tissue profile. The study aimed to provide a theoretical reference in the clinical diagnosis and orthodontic treatment of early permanent dentition of Angle class II division 1 malocclusion patients. We randomly selected 20 cases of orthodontics in Shanxi Medical University orthodontics patients (aged 12-18 years) of the lateral cephalograms, Winceph 8.0 software was used to measure the posterior occlusal plane (OP-P), TUL-EP, TLL-EP, nasolabial angle, upper lip base thickness, upper lip tension, lower lip H line distance, chin soft tissue thickness and Z angle. And SPSS 22.0 software was used to analyze the correlation between OP-P and other measurement indexes. The change of posterior occlusal plane was positively related to the distance from upper lip to the esthetic plane, the distance from lower lip to the esthetic plane, the tension of the upper lip and distance from lower lip to H line, and the change of posterior occlusal plane was negatively related to nasolabial angle and Z angle. The change of posterior occlusal plane had no significant correlation with upper lip base thickness and soft tissue chin thickness. The change of posterior occlusal plane has an important guiding significance for orthodontic treatment,by focusing on the change of the posterior occlusal plane to achieve the purpose of changing the soft tissue profile.
