骨性Ⅱ类错(牙合)畸形患者侧貌相关分析及正畸正颌联合治疗后组织变化
Correlation analysis of facial profile in patients with skeletal Class Ⅱ malocclusion and changes of hard and soft tissue after orthodontic treatment combined with orthognathic surgery
摘要
Abstract
Objective To investigate the effect of orthodontic and orthognathic treatment on patients with skeletal Class Ⅱ malocclusionby studying the changes of soft and hard tissues in maxillofacial region, to analyze the correlation between soft and hard tissues in patients with skeletal class Ⅱ in order to provide reference and guidance for combina-tion therapy. Methods 23 patients with skeletal class Ⅱ malocclusion treated by combined orthodontic and surgical treatment were selected, 21 parameters that can reflect the soft and hard tissue and the facial appearance were recorded in the imaging data before and after orthodontic-orthognathic treatment, The correlation between the soft and hard tissue of the patients before treatment was analyzed. Results There were significant differences between the before and after orthodontic-orthgnathic treatment in the 19 of above mentioned parameters, except for ANS-Me/N-Me(%) and Pg-Pg′(mm). By analyzing the correlation between the hard tissue index and the soft tissue profile of the patients before treat-ment, it can be found that the facial aesthetics is influenced by many hard tissue parameters. Conclusion The effect of orthodontic and orthognathic technique in the treatment of skeletal Class Ⅱ malocclusion is considerable. Hard tis-sue profile of patients with skeletal Class Ⅱ malocclusion forms the basis and support of soft tissue profile. At the same time, soft tissue has some independence. However, the exact quantitative relationship remains to be further studied.关键词
