An open protocol is described for the evaluation of implant deviation by using digital casts. A digital surgical planning cast and a definitive cast are imported into a reverse engineering software program, and cylinders are created as simplifications of the implants. After superimposing the digital casts, implant deviations can be calculated by using the coordinates of the cylinders. This protocol only requires routine clinical data from the guided implant surgery and digital prosthodontic workflow; it can therefore be easily embedded into the clinical procedure. Any dental software program providing access to implant coordinates can be integrated with this protocol to overcome the shortcomings of various closed-loop workflows used by dental software programs.
本研究介绍了一种通过数字化模型评估种植体偏差的开放式方案。通过将数字化手术导板模型和最终模型导入逆向工程软件，利用种植体简化为圆柱体来创建种植体的中心轴。通过对数字化模型进行叠加，利用圆柱体的坐标来计算种植体的偏差。该方案仅需要从引导种植手术和数字化修复流程中获取常规的临床数据，因此很容易整合到临床流程中。任何提供种植体坐标访问权限的牙科软件程序都可以与该方案集成，以克服各种牙科软件程序所使用的封闭式工作流程的局限性。
