摘要目的 :研究青少年双颌前突患者拔牙矫治前后软组织侧貌的变化 ,为临床预测矫治后的软组织侧貌提供临床依据 .方法 :对 1 5例青少年双颌前突患者拔牙矫治前后的 1 0项软组织指标进行对比 ,通过配对t检验来分析治疗后软组织侧貌的变化 .结果 :5项角度测量指标的改变均有统计学意义 ,软组织面角减小 2 .6° ,鼻唇角增大 6 .0° ,面凸角减小 3.1° ,上唇角减小 3.4° ,下唇角增大 3.1° ;5项组织厚度指标中 3项矫治后的变化有统计学意义 ,鼻底厚度减小 1 .4mm ,上唇厚度增大 1 .6mm ,下唇厚度增大 1 .5mm ,鼻根厚度和颏唇沟厚度矫治前后无改变 .结论 :软组织不同部位的改变有所不同 ,拔牙矫治后患者软组织侧貌有明显改变 ,容貌外观得以改善 . AIM: To study the changes in soft tissue profile after orthodontic treatment with four premolars extracted in bimaxillary protrusion in adolescents. METHODS: In 15 adolescents with bimaxillary protrusion, 10 soft tissue controls were compaired before and after orthodontic treatment to evaluate the changes in soft tissue profile with paired t test. RESULTS: Five angular measurements changed statistically. FH N′Pg′, N′ Sn Pg′ and LsSn SN respectively decreased by 2.6°, 3.1° and 3.4°, Cm Sn Ls and LiSi SN respectively increased by 6.0° and 3.1°; in 5 linear measurements 3 changed statistically. Sn A decreased by 1.4 mm, U1 Ls increased by 1.6 mm, Li L1 increased by 1.5 mm; there were no changes in N N′ and Si B. CONCLUSION: There are different changes in the soft tissues according to the various positions, soft tissue profiles are improved significantly after orthodontic treatment with four premolars extraction .
