目的 :研究湖南地区正常恒牙合上下颌之间的牙量关系 ,为牙齿正畸诊断分析和矫治设计提供依据。方法 :精确测量正常恒牙牙合上下颌牙量 ,并进行了Bolton分析和相关资料对比。结论 :确立了湖南地区汉族恒牙牙合上、下颌之间牙量关系的正常比率 ,建立了计算上、下颌前 (全 )牙量的数学模型 ,为临床医师增加了进行错牙合畸形的诊断、矫治设计及判断预后的区域性标准。
OBJECTIVE: To study the relationship between the permanent teeth and the lower jaw in Hunan Province, and provide the basis for the orthodontic diagnosis and orthodontic treatment. Methods: Accurately measure the amount of teeth in normal permanent occlusal and mandibular teeth, and the Bolton analysis and related data were compared. CONCLUSION: The normal ratio of the molar relationship between mandibles and mandibles in Hunan province is established. A mathematical model for calculating the anterior (total) amount of upper and lower jaws is established, which increases the diagnosis of malocclusion , Correcting the design and prognosis of the regional standards.
