| 摘 要： | 目的 研究腭的纵向生长特点并提供一种观察腭整体变化的三维图象分析方法。方法 采用三维图像分析方法对３０例北京地区汉族人正常Ｈｅ替牙期腭的生长变化进行了７－１０岁的纵向观察和研究。结果 发现３０例中１６例腭盖随生长而下降，幅度为１－５ｍｍ；１４例，升高，最大幅度为２．６８ｍｍ。结论三维图像分析方法可直观地反映腭的生长变化，腭盖随生长可下降，也可升降，这可能与个体鼻腔功能的差异有关。

| Abstract: | OBJECTIVE: To investigate the trait of the palate growth and to provide a method of three-dimensional image analysis on revealing the entire variation of palate. METHODS: A longitudinal study on the palate growth of 30 subjects (male 8, female 22) with normal occlusion during mixed dentition was carried out by three-dimensional image analysis. The observation period was from 7 to 10 years of age. RESULTS: During growth, the palate vaults in 16 cases (53%) descend for 1-5 mm, whereas, the palate vaults in 14 cases (47%) ascend for 2.6 mm at most. CONCLUSION: The variations of palate growth can be investigated by three-dimensional image analysis. During growth, the palate vault may descend or ascend, which shows the individual differences of oronasal function. |
