恒牙列早期单侧完全性唇腭裂术后患者牙特征的研究

作者对332名恒牙早期间侧完全性唇腭裂术后患者和同龄正常青少年的牙模型进行测量分析，结果表明：①上颌牙弓、基骨的生长发育受到明显影响，其中腭盖高度发育受限最为明显。②上颌牙弓前段宽度发育受限程度明显大于牙弓后段，上颌结节区宽度缩窄不明显。③上颌与下颌牙弓、基骨关系不协调。

A dental arch morphology study on operated unilateral complete cleft lip and palute patients at the stage of early permaneat dentition

The purpose of this study was to evaluate the characters of dental arch at the stage of early permanent dentition on operated unilateral complete cleft lip and palate patients. The subjects in this study were form two,groups, the cleft gorup was composed of 19 male and 14 female from 13 to 16 years old. The control groupincluded 38 male and 26 female of the similar age to the cleft gorup. All the measurements were obtained byone investigator, intraexaminer and interexaminer reliability were predetermined at O. 5mm. The dental model analysis indicates: (1) the height of the pa1ate decreases evidently. (2) all the measurements of maxillarywidths and lengths are significantly smaller tban the normal dementions except the width between maxillarytuberosity. (3)the growth and development of the maxillary basal bone and denta1 arch shows significant positive correlation.
