摘要
目的:研究深圳地区正常Bolton指数的性别差异,确立正常Bolton指数的范围并对上下颌牙量进行相关性分析和回归方程的建立。方法:选择符合标准的正常模型85例,测得上下牙弓3-3和6-6的长度,计算Bolton指数。结果:上下颌牙弓长度和Bolton指数性别间无统计学意义(P>0.05);上下颌牙量之间存在高度相关性(P<0.01)。结论:确立了深圳地区正常Bolton指数的范围并建立了回归方程,为临床诊断和矫治计划设计提供了依据。
Objective： It is to investigate the rang of Bohon index and different of genders and to relationship between upper and lower teeth dimention and to establish the regression equation. Method： 85 persons with individual normal occlu- sion were selected.To measure the dental arch length and calculate the Bohon index. Result： There were not significant dif- ferences between genders with dental arch length and Bolton index CP 〈0.05） ： there were significant Correlation between up- per and lower tooth （P 〈0.01）. Conclusion： To establish the rang and the regression equation was made which can be applied for diagnosis and orthodontics planning.
