摘　　要：目的:探讨单侧完全性唇腭裂(unilateral complete cleft lip and palate,UCLP)患者应用改良唇挡单侧扩弓后裂侧牙弓宽度变化的稳定性。方法:选取改良唇挡单侧扩弓与保持1年后的UCLP患者16例,男8例,性8例,平均年龄在13.3~14.5岁,对治疗前、扩弓治疗后及保持1年后的CBCT扫描图像进行测量,分别测量裂侧牙尖(颊尖)、牙槽基骨、根尖基骨至正中矢状面的距离,并进行统计学分析。结果:唇挡扩弓治疗后患者上颌裂侧(尖牙、第一、第二前磨牙)颊尖、牙槽基骨、根尖基骨至正中矢状面的距离均增加(P<0.05);保持1年后裂侧上颌颊尖、牙槽基骨至中线的距离较矫治结束时有所减小,根尖基骨至中线的距离少量增加。结论:UCLP患者经改良唇挡单侧扩弓,裂侧尖牙、第一、第二前磨牙牙尖、牙槽基骨、根尖基骨至正中矢状面的宽度均有显著增加,保持1年后扩弓效果稳定。Objective：To evaluate the transverse stability of the dental arch on the cleft side of patients with unilateral complete cleft lip and palate（UCLP） after expansion with modified lip bumper. Methods：The study involved 16 patients with UCLP who had undergone unilateral maxillary expansion. CBCT records bad been taken before unilateral maxillary expansion （T0） , post-treatment（ T1 ） , and after the one-year retention period （T2）. The distance between the buccal tip alveolar bone, root base bones and median sagittal plane on the cleft side was measured. Results：The distance of the median sagittal plane to the buccal tip, alveolar bone and root base bone on the cleft side were significantly increased （P 〈 0. 05 ）. After oneyear retention the distance of the median sagittal plane to the buceal tip and the alveolar bone on the cleft side were with no significant reduced, but the distance of the median sagittal plane to the root base bone increased. Conclusion：The modified lip bumper can effectively increase the width of dental arch, and the long-term effect was stable.
