Abstract

Statement of problem

Computer-guided implant surgery facilitated by intraoral scanning may enhance the efficiency of the digital workflow. However, it is necessary to assess technique accuracy to evaluate the accuracy of implant placement.

Purpose

The purpose of this clinical study was to evaluate the accuracy of a virtual computer-aided design and computer-aided manufacturing (CAD-CAM) static guided surgery technique associated with intraoral scanning in partially edentulous participants by analyzing the overlap among preoperative and postoperative cone beam computed tomography (CBCT) scans, virtual planning, and the guided surgery performed.

Material and methods

Eleven partially edentulous participants underwent CBCT and intraoral scanning (TRIOS3). Data were integrated into a software program (ImplantViewer 3.5) for the virtual planning of implants and 3-dimensional (3D) printing of the prototype CAD-CAM surgical guide. A total of 18 implants were placed using the CAD-CAM static computer-aided implant surgery technique (Strong SW). After 15 days, postoperative CBCT scans were made and 4 variables (angular, coronal, apical, and vertical deviation) were measured to compare the virtually planned implants and the implants placed by analyzing the overlap between preoperative and postoperative of the virtual planning and guided surgery performed using the ImplantViewer 3.5 and Rhino 6 software programs.

Results

Deviations were found in all parameters analyzed. The mean angular deviation was 2.68 ±1.62 degrees; mean coronal deviation, 0.82 ±0.44 mm; mean apical deviation, 1.14 ±0.44 mm; and mean vertical deviation, 0.62 ±0.44 mm.

Conclusions

The implants placed using the CAD-CAM static guided surgery technique associated with intraoral scanning in partially edentulous participants exhibited angular and linear deviations when compared with virtual planning implants. However, these deviations were not clinically significant.

使用全数字化工作流程引导种植牙手术的准确性：病例系列。

问题陈述：通过口内扫描进行计算机辅助种植手术可以提高数字化工作流程的效率。目的：本临床研究的目的是通过分析术前和术后锥形束计算机断层扫描（CBCT）扫描、虚拟规划和所实施的引导手术之间的重叠情况，评估与口内扫描相关的虚拟计算机辅助设计和计算机辅助制造（CAD-CAM）静态引导手术技术在部分无牙颌患者中的准确性：11 名部分无牙颌的患者接受了 CBCT 和口内扫描（TRIOS3）。数据被整合到一个软件程序（ImplantViewer 3.5）中，用于种植体的虚拟规划和 CAD-CAM 手术导板原型的三维打印。使用 CAD-CAM 静态计算机辅助种植手术技术（Strong SW）共植入了 18 个种植体。15 天后，进行术后 CBCT 扫描并测量 4 个变量（角度偏差、冠状偏差、根尖偏差和垂直偏差），通过分析使用 ImplantViewer 3.5 和 Rhino 6 软件程序进行的虚拟规划和引导手术的术前和术后重叠情况，比较虚拟规划的种植体和植入的种植体：所有分析参数均存在偏差。平均角度偏差为 2.68 ±1.62 度；平均冠状偏差为 0.82 ±0.44 毫米；平均根尖偏差为 1.14 ±0.44 毫米；平均垂直偏差为 0.62 ±0.44 毫米：与虚拟规划种植体相比，使用 CAD-CAM 静态引导手术技术和口内扫描技术为部分缺牙患者植入的种植体会出现角度和线性偏差。但是，这些偏差在临床上并不明显。
