摘　　要：目的 :对 5 6名正常牙合青少年的牙、牙弓、基骨进行了计算机辅助牙颌模型测量研究 ,以建立正常值。方法 :5 6副正常恒牙模型 ,用游标卡尺及特制工具测量牙冠宽度、牙弓大小和指数 ,基骨宽度、长度、腭盖高度 ,并进行统计学处理并对其特征进行了分析。结果 :蒙古族人的牙冠宽度除上第一前磨牙 ,下第二磨牙外均为男性大于女性 ;牙弓宽度与基骨宽度为男性大于女性 ,而牙弓长度与基骨长度男女无显著差别 ,Bolton、Pont指数男女无显著差别。与汉族人对比 ,蒙古族人的牙冠宽度大于汉族人 ,蒙古族人牙弓宽度、长度均大于汉族人 ,Bolton前牙比指数、Pont前磨牙指数、磨牙指数也大于汉族人。结论 :蒙古族人牙冠宽度 ,牙弓宽度。Objective: To obtain the data of dental measurements in healthy Mongolia teenages.Methods: Normal dentognathic models were obtained by cephalometric roentgenography in 56 teenages (30 boys and 26 girls) aged 10～17 years. The width of the tooth crown, the size of the dental arch and dental base bone were measured with a vernier. The measurments were statistically analysed.Results: The tooth crown in boys was wider than that in girls( P <0.01) except maxillar first molor and mandibular second molar; the dental arch and dental base bone in boys was wider than those in girls( P <0.01), but was similar in length( P >0.05). There was no significant difference in Bolton index and Point index between boys and girls.Conclusion: The dental measurments may be refrences for dental clinic and research.
