摘  要:目的:评价骨性Ⅲ类错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严重程度和制定治疗方案有重要意义。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 ClassⅢ patients with functional mandibular displacement.
