Abstract：
A technique for the design of a hybrid tooth and bone-supported implant drilling guide is described. The patient was scanned using cone beam computed tomography and an optical intraoral scanner. The dicom file was segmented according to the area of interest composed of bone and the remaining natural teeth. The Standard Tessellation Language (STL) file was trimmed to only the teeth providing support, followed by merging between the bone and teeth files in one STL. The implant drilling guide was designed with the Real Guide software program, and the file was 3-dimensionally printed in clear surgical guide resin. This technique offers an accurate, cost-effective digitally designed implant placement guide for patients with long-span distal extension edentulous areas and few remaining natural dentitions providing distal bone support. It can also be used in patients with hemi maxillectomy for zygomatic implant placement. This type of surgical guide provides more accuracy in implant surgeries that require flab elevation by gaining more support from the remaining natural dentition.
摘要：
描述了一种用于设计混合牙齿和骨骼支撑的植入物钻孔导向器的技术。使用锥形束计算机断层扫描和光学口内扫描仪对患者进行扫描。根据由骨骼和剩余的自然牙齿组成的感兴趣区域来分割dicom文件。标准镶嵌语言(STL)文件被修剪为仅提供支持的牙齿，然后在一个STL中合并骨骼和牙齿文件。种植体钻孔导向器采用RealGuide软件程序设计,文件是用透明的手术导向树脂三维打印的。这种技术提供了一种准确的，具有成本效益的数字设计的植入物放置指南，适用于具有大跨度远端延伸缺牙区和提供远端骨支持的剩余天然牙列的患者。它也可以用于半上颌骨切除术的患者，以进行the骨植入物的放置。这种类型的手术引导件通过从剩余的天然牙列获得更多的支撑,在需要松弛抬高的植入手术中提供更高的准确性。
