Abstract

This clinical report describes the use of a 3-dimensional (3D) printer to create an individual mold for delivering high-dose-rate interventional radiotherapy for hard palate cancer. The maxillary teeth and palate were scanned with an intraoral scanner (3Shape TRIOS 3). The scan was transformed into a mesh using the standard tessellation language (STL) format and aligned with Digital Imaging and Communications in Medicine (DICOM) computed tomography (CT) images using free Blue Sky Plan 4 planning software. A mold was generated by tracing a guideline around the gingival margins of the maxillary teeth and palate on the scan mesh in accordance with established parameters. All data were imported into computer-aided design (CAD) software. For this patient, 3 parallel 2.2-mm-diameter ducts were placed 10 mm from each other in the mold mesh. A CT scan of the patient's mouth with the mold in place was used for treatment planning. Treatment was delivered by means of microSelectron digital afterloading.

摘要

本临床报告描述了使用三维（3D）打印机为硬腭癌的高剂量率介入放疗制作个体化模具的应用。使用口内扫描仪（3Shape TRIOS 3）扫描上颌牙齿和腭部。扫描结果通过标准网格语言（STL）格式转换为网格，并使用免费的 Blue Sky Plan 4 规划软件与数字成像和通信医学（DICOM）计算机断层扫描（CT）图像对齐。根据既定参数，在扫描网格上围绕上颌牙齿和腭部的牙龈边缘追踪一条引导线来生成模具。所有数据均导入计算机辅助设计（CAD）软件。对于该患者，在模具网格中放置了 3 个彼此相距 10 毫米的 2.2 毫米直径的平行导管。将带有模具的患者口腔 CT 扫描用于治疗计划。治疗采用微选择器数字后装技术进行。
