摘　　要：目的探讨应用数字化技术辅助设计并3D打印手术导板,评价其在唇腭裂继发牙颌面畸形正颌外科治疗中应用的可行性和有效性。方法选取2020年5月至2022年4月南阳市口腔医院11例唇腭裂继发牙颌面畸形患者,进行术前CT扫描及牙列模型扫描,重建上下颌骨数字化模型,模拟手术。根据手术设计方案,设计并3D打印手术导板,对比实际术后结果与手术模拟,进行统计分析。结果所有患者均按设计方案成功手术,导板使用顺利,术后结果与手术规划相比,差异无统计学意义(P>0.05)。结论利用数字化技术进行手术设计并3D打印手术导板,可以提高唇腭裂继发牙颌面畸形正颌手术的精确度。Objective To evaluate the effectiveness of digital-aided design and three dimension(3D)printing in the orthognathic surgery for dental-maxillofacial deformities in patients with cleft lip palate.Methods A total of 11 cases of dental-maxillofacial deformities in patients with cleft lip palate in Nanyang Stomatological Hospital from May 2020 to April 2022 were selected.Digital craniomaxillofacial-dentition model was established by combined craniofacial CT and laser-scanned dentition model.Based on this model,surgical planning,simulation and postoperative prediction were performed before surgery.Surgical accuracy was evaluated by comparing the postoperative outcomes with the preoperative surgical planning data,and statistical analysis was performed.Results All patients underwent the orthognathic surgery successfully according to the digital orthognathic surgery design and procedure,and the operation guide plates were applied smoothly.There were no differences between the postoperative actual data and the preoperative planning(P>0.05).Conclusion The digital technology aided design and 3D printing surgical guide plate can improve the accuracy of orthognathic surgery for the dental-maxillofacial deformities in patients with cleft lip palate.
