【摘要】 目的:分析3D打印全程导板辅助口腔种植手术的精准度，评价其在口腔种植中的作用。方法:选取镇江市口腔医院种植修复科在2021年3月至2022年3月期间的41例种植手术，共60颗牙，分成2组：3D打印全程导板种植组和常规种植组，每组各30颗牙。术前拍摄CBCT,2组均进行常规口扫，应用“Dentiq Guide种植导板软件”进行设计，导板组采用3D打印种植全程导板，常规组按照“Dentiq Guide种植导板软件”的设计位置进行常规种植手术。术后即刻拍摄CBCT,应用“Dentiq Guide种植导板软件”将术前、术后CBCT重叠，测量术前设计种植体与术后实际种植体位置，计算两者之间的位置差异，比较使用3D打印种植全程导板和常规种植准确度及术后反应。结果:2组在颊舌向角度、种植体颈部、根部近远中向误差差异均有统计学意义(P<0.01),导板组误差小于常规种植组；术后疼痛方面，导板组也明显轻于常规种植组(P<0.01);2组在近远中向角度误差及术后肿胀方面差异具有统计学意义(P<0.05),导板组小于常规种植组；而在种植体植入深度及种植体颈部、根部颊舌向误差差异均无统计学意义(P>0.05)。结论:应用3D打印导板辅助种植手术，在手术精确度及术后反应方面均优于经验丰富种植医生的常规种植，能实现以修复为导向的精准种植。更多还原

【Abstract】 Objective: To analyze the accuracy of 3D printed whole-course guide plate assisted oral implant surgery, and evaluate its role in oral implantation. Methods: Forty-one cases involving 60 teeth of dental implant were selected. They were implanted between March 2021 and March 2022 in the dental implant department, and they were divided into two groups: Three-dimensional printing whole guide plate planting group and free-hand planting group. Each group involved 30 teeth. CBCT were taken preoperatively in all cases, and routine oral scans were carried out by using “Dentiq Guide software”. Implant operations were performed in the guide plate group, but routine implant surgery in the position designed by the software. CBCT were overlapped before and after operation by using “Dentiq Guide software”. The design implant position was measured before operation and the actual implant position was measured after operation. The location difference was calculated between the two groups, and the accuracy of 3D printed plate was compared with that of free-hand implant surgery. Results: There were significant differences in the buccolingual angulation, implant neck, and apical mesiodistal error between the two groups(P<0.01). The error of the guide plate planting group was smaller than that of the free hand planting group; In terms of postoperative pain, the guide plate planting group was also significantly lighter than that of the free hand planting group(P<0.01); There are differences in the mesiodistal angulation error and postoperative swelling between the two groups(P<0.05); there were no statistically significant differences in the implant placement depth and the buccolingual error at the implant neck and root(P>0.05). Conclusions: The application of 3D printed guide plates in implant surgery is superior to the free-hand planting of experienced planting doctors in terms of surgical accuracy and post response, and it can achieve precise planting oriented by restoration.更多还原
