个性化舌侧矫治技术治疗成人安氏Ⅱ类错牙合的软硬组织变化研究

Abstract

Abstract: To investigate the treatment effects of individualized lingual appliance on adult patients with Angle Class Ⅱ malocclusion. Methods 6 adult patients with Angle Class Ⅱ malocclusion in permanent dentition cases were chosen and treated with individualized bracket system in lingual appliance. Cephalometric analysis before and after treatment were performed. The changes of soft and hard tissue were recorded and analyzed. Results The manifestation of hard tissue change was mainly the decrease of the upper incisor labial inclination while that of soft tissue change was the increase of Cm-Sn-Ls angle and SnLs-SiLi angle. The profile of soft and hard tissue has improved distinctly .Conclusions The application of individualized bracket system in lingual appliance in treating angle class Ⅱ malocclusion of adult patients can also obtain good correction results.

Key words: Angle Class Ⅱ malocclusion, adult patients, individualized bracket system in lingual appliance, soft and hard tissue
