摘　　要：目的:评价3D打印导板在上前牙种植的精确度,探讨其临床效果。方法:选取2017年6月—2018年6月在青岛大学附属医院口腔种植科行上前牙区种植手术的60例患者,采用随机数字表法随机分为G组(导板组)和R组(常规组),每组30例,均在术前拍摄锥形束CT(CBCT),应用“Dentiq Guide种植导板软件”进行设计。G组制作3D打印导板辅助种植手术,R组行常规种植手术。术后即刻拍摄CBCT,应用“Dentiq Guide种植导板软件”将术前、术后CT重叠,测量术前设计与种植体实际位置差异,采用SPSS 24.0软件包对所得数据进行统计分析。结果:G组共植入46颗种植体,测量偏差角度(2.34±1.03)°,顶部(0.63±0.38)mm,根尖部(0.71±0.38)mm,深度(0.41±0.40)mm;R组共植入43颗种植体,测量偏差角度(6.72±3.65)°,顶部(1.59±0.35)mm,根尖部(2.05±0.92)mm,深度(0.77±0.63)mm。2组在角度、顶部、根尖部、深度的差异均有统计学意义(P<0.05)。结论:应用3D打印导板辅助上前牙种植手术,可提高手术精确度,满足种植修复需要,践行以修复为导向的精确种植理念。PURPOSE:To evaluate the accuracy of 3D printed guide plate in implantation of upper anterior teeth and to explore its clinical effect.METHODS:Sixty patients who underwent upper anterior dental implantation from June 2017 to June 2018 were randomly divided into two groups:group G(guide plate group)and group R(conventional group).Each group had 30 patients.Cone-beam CT(CBCT)was taken before operation,and guide plate software Dentiq Guide was used to design the guide plate.Group G used 3D printed guide plate to assist implantation,while group R underwent conventional implantation.CBCT was taken immediately after operation.Preoperative and postoperative CT were overlapped by Dentiq Guide implant guide software.The differences between preoperative design and actual implant position were measured and the data were analyzed statistically with SPSS 24.0 software package.RESULTS:Forty-six implants were implanted in group G.The measured deviation was:angle(2.34±1.03)°,tip(0.63±0.38)mm,apex(0.71±0.38)mm,and depth(0.41±0.40)mm.In group R,43 implants were implanted with the following measured deviation:angle(6.72±3.65)°,tip(1.59±0.35)mm,apex(2.05±0.92)mm,and depth(0.77±0.63)mm.There were significant differences in angle,tip,apex and depth between two groups(P<0.05).CONCLUSIONS:Application of 3D printed guide plate in assisting implantation of upper anterior teeth can improve the accuracy of operation,meet the needs of implant restoration,and practise the concept of precise implantation guided by restoration.
