正常儿童软组织侧貌X线头影测量研究

The study of cephalometry of soft-tissue profile in children with normal occlusion

目的 建立长春市正常牙合少年儿童软组织X线头影测量正常值标准 ,研究软组织侧貌发育的特征。方法 对 10 4例正常牙合样本做X线头影测量分析 ,得出其正常值。对其颌面部软组织侧貌做性别上的特征性分析。结果 得出Holdaway、Burstone、Bishara三种分析法的正常值及其他测量项目的正常值。 结论 虽然男女软组织侧貌发育特征很相近 ,但仍存在一定差异。了解正常牙合人群软组织侧貌的发育特征 ,有助于临床诊断及矫治计划的制定。

Objective To establish the normal values of cephalometry of soft-tissue profile in Changchun children with normal occlusion and to study the development characteristic of soft-tissue profile.Methods The cephalometric radiographs of 104 teenagers with normal occlusion were analyzed and the normal values were calculated.The difference of soft-tissue profile on different genders was analyzed.Results The normal values measured with Holdaway, Burstone and Bihara cephalometric analysis methods and normal values of other measurement items were established.Conclusion Although both genders have similar development characteristic of soft-tissue profile,there still exist some differences.To understand the development characteristic of soft-tissue profile in population with normal occlusion is contributed to clinical diagnosis and treatment planning.
