简介：本研究的目的是评估骨和牙齿的变化，在上颌骨患者的分裂治疗与3个扩展器：蹄兔，风扇型，倒置迷你蹄兔支持的第一前磨牙。研究方法：将30例单侧唇腭裂伴上颌骨横向缺损的患者根据所用扩弓器的类型分为3组。在扩张前和扩张后3个月拍摄锥形束计算机断层扫描图像，采用配对t检验评估各组的变化。结果：倒置小蹄兔组上颌骨有明显的前移（P
Introduction: The purpose of this study was to evaluate the skeletal and dental changes in the maxillae of patients with clefts treated with 3 expanders: hyrax, fan-type, and inverted mini-hyrax supported on the first premolars. Methods: Thirty patients with unilateral cleft lip and palate with transverse maxillary deficiency were divided into 3 groups, according to the type of expander that they used. Cone-beam computed tomography images were taken before and 3 months after expansion, and the paired t test was used to evaluate the changes in each group. Results: The subjects in the inverted mini-hyrax group showed significant forward displacement of the maxilla (P
