摘　　要：目的:建立哈尔滨市正常人群的前平面及后平面的参考数据;得出前后平面与骨骼和牙齿各参数的相关性。方法:选取符合标准的正常100名,拍摄正中位X线头颅侧位定位片,定点测量后进行数据统计。结果与结论:哈尔滨市正常人群的前平面参考正常均值为9.82,标准差为3.00;后平面参考正常均值为17.95,标准差为3.25;平面差的参考正常均值8.13,标准差为2.55。骨骼参数方面,前平面与MP(下颌平面角)、R-I(下颌升支高度)密切相关;后平面与MP(下颌平面角)、FX(面轴角)、R-I(下颌升支高度)密切相关。牙齿参数方面,前平面与U1-FH、U1-PP、U5-PP、L7-MP密切相关;后平面与U1-FH、U6-FH、U1-PP、U7-PP密切相关。Objective：To establish the reference value of anterior and posterior occlusion planes of Harbin normal occlusion and evaluate the associativties among occlusion planes,teeth and the skeletal. Methods：100 normal occlusions were selected. After taken X-ray lateral cephlograms,the data were measured and analyzed by statistics. Results and Conclusion：The values of anterior and posterior occlusion planes of normal occlusion are respectively 9.82 degrees with a SD of 3.00 and 17.95 degrees with a SD of 3.25. The mean of occlusion plane is 8.13 degrees with a SD of 2.55.In skeletal,anterior occlusion planes was correlated with MP,R-I,while the posterior occlusion planes was correlated with MP,R-I and FX. In teeth,anterior occlusion planes was correlated with U1-FH,U1-PP,U5-PP and L7-MP,while the posterior with U1-FH,U6-FH,U1-PP and U7-PP.
