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: To study the gender difference of Bolton index in Shenzhen area, establish the range of Bolton index and establish the correlation analysis and the regression equation of upper and lower jaw tooth volume. Methods: A total of 85 normal models were selected. The lengths of 3-3 and 6-6 were measured and the Bolton index was calculated. Results: There was no significant difference between the maxillary and mandibular dental arch length and the Bolton index (P> 0.05). There was a high correlation between the maxillary and mandibular dental parameters (P <0.01). Conclusion: The range of normal Boll index in Shenzhen area was established and the regression equation was established, which provided the basis for clinical diagnosis and correction plan design.
