摘　　要：目的观察3D打印临时冠在后牙连续缺失种植修复中的临床应用效果。方法选择2019—2020年在我院就诊的双侧后牙游离缺失患者共50例,植入同一种植体系统,种植修复时,患者随机分为2组,每组25例,分别为对照组及试验组。对照组为直接完成组,根据印模及咬合硅橡胶完成最终修复体制作。试验组为临时冠组,采用3D打印先制作临时冠,再根据临时冠试戴情况调整后制作最终修复体。最终修复体完成后,比较两组修复体试戴总花费时间,精确度以及患者满意度。结果试验组试戴花费总时间比对照组短(P<0.05),修复体精确度更高(P<0.05),患者满意度高(P<0.05),差异具有统计学意义。结论对后牙连续缺失种植病人进行修复时,临时冠具有一定的应用价值。Objective To investigate the clinical outcome of 3 D printing temporary crown for dental implant restoration in the posterior region.Methods Fifty patients with continuous tooth missing in posterior teeth area were selected and divided into two groups.All patients selected the same implant system.In the control group,the final restoration was directly completed according to the impression.In the experimental group,3 D printing temporary crown was used and adjusted according to clinical performance before final restoration.After the prosthodontics was fixed,chair-side time,the accuracy of final restoration and patients’satisfaction were evaluated and analyzed.Results The chairside time of experimental group was significantly less than the control group(P<0.05).Moreover,the accuracy of restoration and satisfaction of patient in the experimental group were also higher than those in the control group(P<0.05).Differences were statistically significant.Conclusion 3 D printing temporary crown has certain application value in the continuous missing tooth area,which benefits both doctors and patients.
