3D打印辅助手术治疗下颌骨缺损疗效的Meta分析

Abstract

Abstract: Objective: To evaluate the effect of 3D printing technology applied in the reconstruction of defected mandibular through the published literatures by Meta-analysis. Methods: The PubMed, MEDLINE, Cochrane library, Embase, CBM, CNKI and WanFang databases were searched from the date of database foundation to January 2019 to collect the controlled clinical trials in witch 3D printing technology was applied in mandibular reconstruction.Methodology quality of the trials was assessed critically and relative data were extracted, followed by analysis on the RevMan5.3 software. Results: Totally 10 controlled clinical trials including 268 cases were chosen.Among them,124 cases were assigned to the 3D printing technology group and 144 cases to the conventional group.The Meta-analysis results showed that the ischemic time [SMD=-39.78, 95%CI(-57.85,-21.71), P<0.01], reconstruction time[SMD=-31.90, 95%CI(-43.12,-20.68), P<0.01] and the operative time [SMD=-76.93, 95%CI(-106.93,-46.92), P<0.01] in the 3D printing technology were all lower than those in the conventional group, the accuracy of mandibular reconstruction was higher than the conventional group. Conclusion: 3D printing technology applied in the reconstruction of mandibular has the advantage of shorter ischemic time, reconstruction and operative time, and can improve the accuracy of mandibular reconstruction and improve the efficiency and quality of surgery.
