摘要： 目的:评价骨性Ⅲ类错牙合患者牙尖交错位与后退接触位的头影测量数据差异。方法:选择16例伴下颌有功能性移位的骨性Ⅲ类患者,(RCP位ANB<0°),测量分析治疗前ICP位与RCP位的头颅侧位片。使用SPSS17.0统计软件对数据进行统计分析。结果:在ICP位与RCP位,骨性指标SNB角、颌突角、FMA角、MP-SN角、Y轴角及N-per to Pog距离、ANB角、Wits值、APDI值、反覆盖、ODI值均有显著性统计学差异(P<0.001)。牙性指标U1-L1角(P<0.01),FMIA角(P<0.001)有统计学差异。软组织指标颏前点至零子午线距离(P<0.001),Z角(P<0.01)也有统计学差异。结论:对于存在功能性移位的骨性Ⅲ类患者,术前RCP位头颅侧位片分析对诊断错牙合严重程度和制定治疗方案有重要意义。

Abstract: Objective: To investigate the difference of cephalometric analysis between intercuspal position (ICP) and retruded contact position (RCP) in skeletal Class Ⅲ malocclusion patients. Methods: Included in this study were 16 skeletal Class Ⅲ malocclusion patients with functional mandibular displacement. Lateral cephalograms in both ICP and RCP positions were taken and analyzed. Results: The analysis of skeletal indices showed that SNB angle, Angle of convenxity, FMA angle, MP-SN angle, Y axis angle, distance from N-per to Pog, ANB angle, Wits, APDI, Cross overjet and ODI were significantly different between two positions (P<0.001). The analysis of dental indices showed that U1-L1 angle and FMA angle were statistically different (P<0.01 and P<0.001, respectively). The analysis of soft tissue indices showed that the distance from O-M to Pog' and Z angle were statistically different (P<0.001 and P<0.01, respectively). Conclusion: It is important to take and analyze lateral cephalogram in retruded contact position for diagnosing and treating skeletal Angle Class Ⅲ patients with functional mandibular displacement.
