摘　　要：目的:探讨三维重建下3D打印技术在下颌骨缺损修复手术中的应用效果。方法:选择在南京医科大学附属口腔医院行下颌骨缺损修复重建的84例患者作为研究对象,根据治疗方式不同分为3D组(42例)和对照组(42例),对照组行常规手术,3D组采用数字三维重建3D打印技术辅助手术。记录2组的手术情况、手术并发症发生率及面容、咬合关系恢复情况等。采用SPSS23.0软件包对数据进行统计学处理。结果:3D组患者的手术时间比对照组短,术中出血量比对照组少(P<0.05)。3D组患者面容及咬合关系的恢复优良率(95.24%)比对照组(78.57%)显著提高(P<0.05)。与对照组相比,3D组手术前、后下颌骨各位点的移动距离均显著减小(P<0.05)。2组术后咀嚼功能、发音情况恢复满意度评分接近(P>0.05),但与对照组相比,3D组对外貌恢复的满意度评分更高(P<0.05)。结论:在下颌骨缺损修复重建手术中,采用三维重建3D打印技术能够减少术中出血,缩短手术时间,外形恢复良好,患者满意度高。PURPOSE: To explore the application value of 3D printing technology under three-dimensional reconstruction in mandibular reconstruction. METHODS: Eighty-four patients with mandibular defect reconstruction were divided into two groups by different operation methods: 3D group(n=42) and control group(n=42). Patients in the control group underwent routine operation, while patients in the experimental(3D) group underwent three-dimensional reconstruction with 3D printing technology. The operation conditions, incidence of complications, recovery of facial features and occlusal rela-tionship were recorded. SPSS 23.0 software package was used for statistical analysis of the data. RESULTS: The operation time of 3D group was significantly shorter than that of the control group, and the amount of bleeding was significantly less than that of the control group(P<0.05). The recovery rate of facial appearance and occlusal relationship in 3D group was significantly higher than in the control group(95.24% vs 78.57%, P<0.05). Compared with the control group, the movement distance of mandibular points in 3D group was significantly smaller before and after operation(P<0.05). The satisfaction scores of chewing function and pronunciation recovery in the two groups were close(P>0.05), but compared with the control group, the satisfaction scores of appearance recovery in the 3D group were significantly higher(P<0.05). CONCLUSIONS:3D reconstruction under 3D printing technology can reduce intraoperative bleeding, shorten the operation duration, and achieve good shape recovery with high degree of satisfaction.
