在这方面的贡献，提出了一种新的方法，计算机辅助手术计划的面部缺陷，使用模型的采购MedArtis Modus 2.0微型板。属于骨合成材料的这种植入物通常用于治疗面部区域的缺陷。通过将它们垂直放置在缺损处，微型板固定在健康骨上，相对于表面弯曲，以稳定缺损区域。我们的软件能够在3D计算机模型中将最常见的种植体模型选择到外科医生的期望位置。该拟合遵循局部曲面曲率并以任何所需方式调整方向和位置。传统方法使用计算机断层扫描（CT）扫描来生成用作植入物的弯曲模板的STEreoLithic（STL）模型，或者在手术期间使用弯曲工具来多次重新调整植入物。这两种方法都会导致不必要的时间开销。借助我们的视觉规划工具，外科医生能够在几分钟内预先规划最终植入物。生成的模型可以以STL格式存储，这是3D打印常用的格式。有了这项技术，外科医生能够及时打印植入物或使用它来生成弯曲工具，两者都导致精确弯曲的微型板。
In this contribution, a novel method for computer aided surgery planning of facial defects by using models of purchasable MedArtis Modus 2.0 miniplates is proposed. Implants of this kind, which belong to the osteosynthetic material, are commonly used for treating defects in the facial area. By placing them perpendicular on the defect, the miniplates are fixed on the healthy bone, bent with respect to the surface, to stabilize the defective area. Our software is able to fit a selection of the most common implant models to the surgeon's desired position in a 3D computer model. The fitting respects the local surface curvature and adjusts direction and position in any desired way. Conventional methods use Computed Tomography (CT) scans to generate STereoLithic (STL) models serving as bending template for the implants or use a bending tool during the surgery for readjusting the implant several times. Both approaches lead to undesirable expenses in time. With our visual planning tool, surgeons are able to pre-plan the final implant within just a few minutes. The resulting model can be stored in STL format, which is the commonly used format for 3D printing. With this technology, surgeons are able to print the implant just in time or use it for generating a bending tool, both leading to an exactly bent miniplate.
