The purpose of this study was to evaluate the fabrication of a complete denture using a CAD/CAM system. Cone beam CT was used to measure the complete denture and the artificial teeth. After a 3D complete denture image was structured using 3D CAD software, we factored out the artificial teeth and obtained a 3D denture base image. A machining center cut an acrylic resin block, and fabricated an acrylic complete denture base. The artificial teeth were bonded to the cut denture base using resin cement. A 3D digitizer digitized the fabricated acrylic denture. We measured the deviations between the master 3D complete denture image and the 3D data of the fabricated acrylic denture. The average deviations from the master 3D image were 0.50 mm for the occlusal surface. This present study indicates that it is possible to fabricate a complete denture using a CAD/CAM system.
本研究旨在评估使用 CAD/CAM 系统制作全口义齿。通过锥形束 CT 测量全口义齿和人工牙。使用 3D CAD 软件构建 3D 全口义齿图像后，我们提取人工牙并获得 3D 基托图像。加工中心切割丙烯酸树脂块，并制作丙烯酸树脂全口义齿基托。使用树脂水门汀将人工牙粘接到切割好的义齿基托上。3D 数字化仪对制作好的丙烯酸义齿进行数字化。我们测量了主 3D 全口义齿图像和制作好的丙烯酸义齿的 3D 数据之间的偏差。在咬合面，从主 3D 图像的平均偏差为 0.50 毫米。本研究表明，使用 CAD/CAM 系统制作全口义齿是可行的。
