目的获取诊断恒牙早期牙、骨性反牙合的主要指标。方法从给出明确牙、骨性反牙合诊断的８５例恒牙早期前牙反牙合病例中，随机抽取７０例，利用逐步判别分析获得诊断所需的主要指标，用另１５例检验，通过计算各指标贡献率对其诊断作用进行评价。结果得到６项指标：ＣｏＧｎ、ＡＯＢＯ、Ｓ－Ｐｔｍ、ＡＮＢ、ＭＰＰＰ、ＲａｍｕｓＡｎｇｌｅ。结论该６项指标包含了区分牙骨性反牙合所需的大部分信息
Objective To obtain the main indexes of diagnosing early teeth and bony anti-occlusion of permanent teeth. Methods From 85 cases of anterior teeth and anterior teeth with definite teeth and bony anti-occlusal diagnosis, 70 cases were randomly selected, and the main indexes needed for diagnosis were obtained by stepwise discriminant analysis. Another 15 cases were used for the test, By calculating the contribution rate of each index to evaluate its diagnostic role. The results obtained six indicators: CoGn, AOBO, S-Ptm, ANB, MPPP, RamusAngle. Conclusion The six indicators contain most of the information needed to distinguish between bony anti-occlusion
