摘要:

文题释义:

3D打印种植导板:患者术前锥形术CT数据与光学扫描数据通过计算机进行三维数字化整合重建。根据牙槽骨条件及修复体位置设计种植体最佳位置,多层次连续打印生成的导板。

3D打印数字化口腔技术的优势:能控制种植体植入三维位置(方向、角度、深度),实现“以修复为导向”的种植外科,增加修复效果的可预期性,以及降低手术风险,减少手术时间,并可实现微创不翻瓣种植等优势。

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。

Abstract:

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.

Key words: digital surgical guide, dental implant, accuracy analysis, probing depth, modified plaque index, modified sulcular bleeding index
