摘　　要：背景:上前牙美学区常规种植难以获得理想三维位置,对种植精度要求较高。目的:评价3D打印数字化导板在上前牙种植中的临床应用效果。方法:86例需行牙种植患者分为2组,对照组43例(52枚种植体)采用常规种植方法,试验组43例(52枚种植体)在3D打印数字化导板下种植。种植体植入后测量三维位置精度,修复后6个月时检查改良菌斑指数、龈沟出血指数、探诊深度,以及记录患者对种植义齿的主观满意度。结果与结论:①试验组种植后顶端垂直向、水平向误差,根端垂直向、水平向误差明显小于对照组,差异有显著性意义(P<0.05);②试验组的改良菌斑指数、龈沟出血指数、探诊深度明显低于对照组,差异有显著性意义(P<0.05);③试验组的患者满意度达到98%(42/43),高于对照组86%(37/43);④结果表明,3D打印数字化导板用于口腔种植义齿中,可以提高种植后的三维位置精度,改善术后临床效果。BACKGROUND:Conventional implantation at anterior aesthetic region is difficult to achieve ideal three-dimensional position,and needs high implantation accuracy.OBJECTIVE:To evaluate the clinical application effect of three-dimensional printed digital guide technology in anterior dental implant.METHODS:Eighty-six cases of dental implants were divided into two groups.Control group(n=43,52 implants)received conventional dental implantation.Trial group(n=43,52 implants)received implantation under three-dimensional printed digital guides.The accuracy of the three-dimensional position of the implants was measured.The modified plaque index,modified bleeding index,probing depth and the satisfaction of patients with implant denture were measured at 6 months after implantation.RESULTS AND CONCLUSION:(1)The errors of vertical and horizontal directions at the top and the root after implantation in the trial group were significantly fewer than those in the control group(P<0.05).(2)The modified plaque index,modified bleeding index,and probing depth in the trial group were significantly lower than those in the control group(P<0.05).(3)The satisfaction of patients in the trial group was 98%(42/43),which was higher than 86%(37/43)in the control group.(4)In summary,three-dimensional printed digital guide plate used in dental implant dentures can improve the three-dimensional position accuracy after implantation and improve the postoperative clinical effect.
