摘　　要：目的观察单侧完全性唇腭裂术后患者腭裂隙内骨再生情况，探究其对牙弓形态发育的影响。方法随机选取35例单侧完全性唇腭裂术后患者作为观察组，20例正常牙颌作为对照组，所有研究对象均行cT高分辨平扫。在观察组中，根据是否有骨桥形成进一步分为有骨桥形成组、无骨桥形成组。测量有骨桥形成组再生骨的情况；分别测量观察组及对照组牙弓前段、中段、后段宽度，对测量结果行统计学分析。结果①观察组共计25例腭突有不同程度的骨再生并相互连接形成骨桥，余下10例腭裂隙内可见不同程度的再生骨形成，但未连接形成骨桥。②观察组中有骨桥形成组牙弓中段宽度大于无骨桥形成组；观察组牙弓各段宽度均小于对照组。结论腭裂术后腭裂隙内均有不同程度的再生骨；骨桥的形成有利于牙弓形态更好地发育。Objective To observe the regeneration of palatal fracture in patients with unilateral complete cleft lip and palate. Methods A total of 35 patients with unilateral complete cleft lip and palate were randomly included as the observation group and 20 with normal teeth as the control group. All the subjects underwent CT with high resolution. Based on the formation of bone bridge, the observation group was further divided into bone bridge formation group and non-bone bridge formation group. The regenerated bone of the bone bridge was measured. The width of the anterior segment, middle segment and posterior segment of the dental arch were measured and statistically analyzed between the observation group and the control group. Results （1）A total of 25 cases with varying degrees of regenerated bone was interconnected to form bone bridge in palatal process, while in the remaining 10 cases, bone was regenerated, but not connected to form bone bridge. （2）The width of the middle section of the arch in the observation group was greater than that in the non-bone bridge formation group. The width of each segment in the observation group was less than that in the control group. Conclusions Bone was regenerated to various extent in the palate after cleft palate. The formation of bone bridge is beneficial to the development of dental arch.
