安氏Ⅱ类错(牙合)患者Spee曲线深度与牙颌面形态间的关系
Relationship between depth of the curve of Spee and dentalfacial morphology in Angle Class Ⅱ maloclusion patients
摘要
Abstract
Objective To compare the depth of the curve of Spee in Angle classⅡmalocclusion patients with dif-ferent vertical skeletal patterns and to investigate the relationship between the depth of the curve of Spee and dentofa-cial morphology. Methods 101 Angle classⅡmalocclusion patients were selected and randomly divided into 3 groups based on their GoGn-SN angles-high angle, average angle and low angle. Lateral cephalograms and dental models of all patients were evaluated to analyze Spee curve depth difference among different groups, Correlation analysis and a multi-ple linear regression analysis were performed to determine the relationship between the depth of the curve of Spee and all selected cephalometric variables. Results There was statistical difference in depth of the curve of Spee among dif-ferent groups P < 0.05. The depth of the curve of Spee was least in the high angle group and greatest in the low angle group. GoGn-SN angle had statistically significant negative correlation with the depth of the curve of Spee, r = 0.428, P=0.000, ODI, S-Go/N-Me、L7-GoGn angle had statistically significant positive correlation with the depth of the curve of Spee, r=0.381, 0.357, 0.333, P=0.000, 0.000, 0.001. The multiple linear regression analysis with stepwise method showed GoGn-SN angle had significant contribution to the depth of the curve of Spee. Conclusion In Angle classⅡmalocclusion patients, there was statistical difference in depth of the curve of Spee among different vertical skeletal pat-terns. The depth of the curve of Spee is correlated with dentofacial morphology, GoGn-SN angle had significant contribu-tion to the depth of the curve of Spee, which should be taken into consideration during orthodontic diagnosis and treat-ment.关键词
