摘　　要：目的 评价计算机辅助设计的唇腭裂术前矫治疗效,以期为临床提供参考.方法 选取单侧完全性唇腭裂40例,术前矫治组患者20例（男性16例,女性4例）,对照组患者20例（男性15例,女性5例）;术前矫治组进行计算机辅助设计的术前鼻-牙槽骨塑形矫治,对照组不进行术前矫治.使用Rapdiform XOR3软件对两组患者的上颌牙槽数字模型进行形态学测量,并对两组各测量项目进行独立样本t检验,对术前矫治组矫治前后各项目进行配对t检验.结果 术前矫治组患者矫治后唇裂裂隙宽度为（4.6±3.5） mm,上颌中线偏斜量为（2.8±2.0）mm,裂隙侧乳尖牙区牙槽骨垂直高度为（3.7±1.1） mm,非裂侧为（4.6±0.9） mm,与矫治前相比差异均有统计学意义（P＜0.05）,与对照组相比差异均有统计学意义（P＜0.05）.结论 计算机辅助设计的术前鼻-牙槽骨塑形治疗是有效的唇腭裂新生儿术前矫治方法,能实现精确量化的上颌牙槽骨块移动,但可能导致牙槽骨高度降低.Objective To develop a new method of presurgical nasoalveolar molding based on computer-aided design technique.Methods Twenty patients（1 6 boys, 4 girls） with complete unilateral cleft lip and palate（UCLP） who received presurgical nasoalveolar molding were recruited as the treatment group.Twenty patients（15 boys, 5 girls） with complete UCLP who did not receive presurgical orthopedic treatment were selected as the control group.All parameters of the digital maxillary model were measured using the Rapidform XOR3 software.The statistical analysis was performed with SPSS 15.0.Results A’-X and B-Il were reduced significantly after presurgical nasoalveolar molding.However, the mean alveolar height [F-hight （3.7± 1.1） mm, F’-height （4.6±0.9） mm] decreased significantly after treatment（P〈 0.05）.There were significant differences between the treatment group and the control group（P〈0.05）.Conclusions Maxillary alveolar morphology could be improved in UCLP infants treated with computer-aided presurgical nasoalveolar molding.The width of the cleft could be reduced and the maxillary midline corrected effectively.However, the alveolar height decreased significantly after the treatment.
