To explore the application value of 3D printing technology under three-dimensional reconstruction in mandibular reconstruction.
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 relationship were recorded. SPSS 23.0 software package was used for statistical analysis of the data.
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).
3D reconstruction under 3D printing technology can reduce intraoperative bleeding, shorten the operation duration, and achieve good shape recovery with high degree of satisfaction.
探讨三维重建下3D打印技术在颌骨重建中的应用价值。
将84例颌骨缺损重建患者按不同手术方法分为两组：3D组（n = 42）和对照组（n = 42）。对照组患者接受常规手术，而实验组（3D组）患者采用3D打印技术进行三维重建。记录手术情况、并发症发生率、面部外形及咬合关系恢复情况。采用SPSS 23.0软件包对数据进行统计分析。
3D组手术时间明显短于对照组，出血量明显少于对照组（P < 0.05）。3D组面部外形及咬合关系恢复率明显高于对照组（95.24% 对78.57%，P < 0.05）。与对照组相比，3D组下颌点术前术后移动距离明显更小（P < 0.05）。两组咀嚼功能及发音恢复满意度评分相近（P > 0.05），但与对照组相比，3D组外形恢复满意度评分明显更高（P < 0.05）。
3D打印技术下的三维重建可减少术中出血，缩短手术时长，并实现良好的外形恢复，满意度高。
