摘要： 目的：探讨SanderⅢ矫治器矫治早期骨性Ⅲ类错后软、硬组织变化和垂直向相关性。方法：选择32例拟行SanderⅢ矫治器矫治的早期骨性Ⅲ类错患者,观察矫治前、矫治12个月后软、硬组织变化,分析软组织与垂直向的相关性。采用SPSS 25.0软件包对数据进行统计学分析。结果：矫治12个月后SNB缩小（P<0.05）,ANB、 A-PTV、Go-Me增加（P<0.05）,软组织指标LL-LI增加（P<0.05）,LL-EP减少（P<0.05）,矫治后L1/MP缩小（P<0.05）,U1E-PTV增加（P<0.05）。相关性分析显示,UL-UI与倾斜角、U1E-PP、U6E-PP呈正相关（P<0.05）,LL-LI与倾斜角、U1E-PP、U6E-PP呈负相关（P<0.05）,Sn-UL/FH与U6E-PP呈正相关（P<0.05）。结论：SanderⅢ矫治器可有效矫正早期骨性Ⅲ类错患者软、硬组织畸形,唇部形态随硬组织骨性关系改善而趋于协调,软组织指标与硬组织垂直向关系密切。

Abstract: PURPOSE: To explore the correlation between the soft and hard tissue changes and the vertical direction of early skeletal Class Ⅲ malocclusion treated with Sander Ⅲ appliance. METHODS: Thirty-two patients with skeletal Class Ⅲ malocclusion who underwent Sander Ⅲ appliance correction were enrolled. The changes of soft and hard tissues were observed before and after treatment for 12 months. The correlation between soft tissue and vertical direction was analyzed. SPSS 25.0 software package was used for statistical analysis. RESULTS: After 12 months of treatment, SNB decreased (P <0.05), ANB, A-PTV, Go-Me increased (P<0.05), soft tissue index LL-LI increased (P<0.05), LL-EP decreased (P<0.05). L1/MP was reduced after treatment (P<0.05), and U1E-PTV was increased (P<0.05). Correlation analysis showed that UL-UI was positively correlated with tilt angle, U1E-PP and U6E-PP(P<0.05); LL-LI was negatively correlated with tilt angle, U1E-PP and U6E-PP (P<0.05). Sn-UL/FH and U6E-PP were positively correlated (P<0.05). CONCLUSIONS: Sander Ⅲ appliance can effectively correct the soft and hard tissue deformity of patients with early skeletal Class Ⅲ malocclusion. The shape of the lip tends to be coordinated with the improvement of hard tissue. The soft tissue index is closely related to the vertical direction of the hard tissue.
