摘　　要：目的测量一般人群的牙齿磨耗量和颅面形态参数,以研究颅面结构特征对牙齿磨耗分布的影响。方法针对收集到的103例正畸患者初始数据,运用Adobe Photoshop软件测量每颗牙齿的磨耗面积,通过头颅侧位片测量ANB、FMA、FMIA、FH-Mx Occ Plane等交角,分析颅面结构与磨耗面积的相关性。结果ANB角与总磨耗面积以及前后牙平均磨耗面积正相关;FMA角与前后牙磨耗面积的比值负相关;FMIA角与后牙平均磨耗面积负相关;FH-Mx Occ Plane角与前后牙磨耗面积的比值存在着负相关。结论一般人群中牙齿的磨耗量与颅面结构特征存在一定的相关性,过陡的咬合平面可以导致后牙磨耗更为严重。Objective To perform a dental examination of the general population,measuring tooth wear and craniofacial morphological parameters to study the effects of craniofacial structural features on tooth wear distribution.Methods For the initial data of 103 orthodontic patients,the wear area of each tooth was measured on the model by Adobe Photoshop,and the cephalometry of the patient was subjected to head ANB,FMA and FMIA,and the correlation between cephalometric data and tooth wear was analyzed.Results ANB was positively correlated with the total wear area and the average wear area of the anterior and posterior teeth.FMA was negatively correlated with the ratio of the wear area of the anterior and posterior teeth.FMIA was negatively correlated with the average wear area of the posterior teeth.FH-Mx Occ Plane was negatively correlated with the ratio of the wear area of the anterior and posterior teeth.Conclusion There is a certain correlation between the wear area of the teeth and the cephalometric measurement in the general population.The too steep occlusal plane can cause more serious posterior tooth wear.
