摘要/Abstract

摘要： 目的：通过计算机虚拟设计联合数字化手术导板技术,模拟自体牙移植术后的位置,同时辅助自体牙移植牙槽窝的精确预备。方法：选取10例自体牙移植手术患者,将其锥形束CT（CBCT）数据导入Proplan CMF 3.0软件。根据咬合和空间情况匹配移植牙,并将虚拟的移植牙转移至受植区,同时设计用于预备牙槽窝的数字化手术导板。利用计算机快速成型技术打印出手术导板和移植牙的3D模型。结果：计算机虚拟设计联合数字化导板技术,能够快速精确地引导受植区牙槽窝的精确预备。通过6个月随访,影像学检查显示所有病例均可见连续牙周膜影像,临床检查显示移植牙无明显松动,未探及明显牙周袋（<4 mm）,术后具有较高的存活率和成功率。结论：计算机虚拟设计能够准确模拟自体牙移植术后的位置,简化手术过程,提高受植区牙槽窝预备的精确性。

Abstract: PURPOSE: It was aimed to apply computer virtual design and digital surgical templates to simulate postoperative position of tooth and guide the accuracy of socket preparation during tooth autotransplantation. METHODS: The study enrolled 10 patients who underwent tooth autotransplant surgery. Cone-bean CT (CBCT) data were imported into Proplan CMF 3.0 software. The donor tooth was transferred to the recipient site according to the occlusion and space situation. A digital template was designed to guide socket preparation. Computer-aided rapid prototyping (RP) technique was used to print the surgical template and tooth model. RESULTS: With computer virtual design and digital template, it was possible to accurately guide socket preparation in recipient site. The six-month follow-up results showed the periodontal space in the radiographs was continuous and intact. There was no mobility in all cases and the probing depth of the tooth was <; 4 mm. The related data showed a favorable survival and success rates of the donor teeth. CONCLUSIONS: Computer virtual design can successfully simulate postoperative position in tooth autotransplantation while simplifying the surgical procedure, and enhance the accuracy of socket preparation.
