摘要：

目的 分析未经手术修复腭裂患者的牙颌形态学特征。方法 以40例未接受手术修复的恒牙列期腭裂患者作为研究对象，其中单侧完全性唇腭裂（UCLP）患者15例，中位年龄20.2岁；单纯腭裂（ICP）患者 25例，中位年龄21.8岁。分别对两组患者上颌牙颌模型进行相关指标测量和分析，以40例年龄、性别匹配的AngleⅠ类错畸形患者作为对照组。结果 与对照组比较，UCLP组患者前段牙弓宽度缩窄，前段牙弓长度及总牙弓长度明显缩短，差异有统计学意义（P<0.05）；ICP组患者后段牙弓宽度增宽，前段牙弓长度和总牙弓长度明显缩短，差异有统计学意义（P<0.05）。结论 未接受手术修复的腭裂患者均存在上颌矢状向发育障碍；其中UCLP患者前牙区存在一定的横向发育不足。

Abstract:

Objective To analyse the characteristics of appearance of dental arch of patients with unrepaired cleft palate. Methods Forty patients with unrepaired nonsyndromic cleft palate were collected, among whom 15 had unilateral cleft lip and palate (UCLP) with the mean age of 20.2 years old, and the other 25 had isolated cleft palate (ICP) with the age of 21.8 years old. Dental cast assessments were conducted in two groups. Besides, 40 age and gender-matched patients with classⅠ malocclusion were served as controls. Results Compared with controls, patients with UCLP had decreased anterior dental-arch width, anterior dental-arch length and total dental-arch length (P<0.05), while those with ICP had increased posterior dental-arch width, decreased anterior dental-arch length and total dental-arch length (P<0.05). Conclusion There exist inhibitory effects of sagittal growth and maxilla development in patients with unrepaired cleft palate, while inhibitory effects of transverse growth in canine region only exist in patients with UCLP.
