This article describes a technique where an interim computer-aided design and computer-aided manufacturing (CAD-CAM) prosthesis is milled from a poly(methyl methacrylate) blank to confirm esthetics, occlusion, function, phonetics, and accessibility for oral hygiene. The interim prosthesis is then sectioned and reconnected intraorally with autopolymerizing acrylic resin. This interim prosthesis is used to fabricate the definitive stone cast. The interim prosthesis is then scanned with a laboratory scanner. By applying this technique, the implant positioning can be related to the occlusal plane, the contours of the teeth, and the flange. The clinician can more effectively design the definitive prosthesis because the location of the implants and the exact contours of the teeth are all captured in a single digital file.
本文描述了一种技术，通过从聚甲基丙烯酸甲酯毛坯中铣削出临时计算机辅助设计和计算机辅助制造 (CAD-CAM) 修复体，以确认美观、咬合、功能、语音和口腔卫生的可及性。然后将临时修复体切开并在口腔内重新用自聚合丙烯酸树脂连接。然后用这个临时修复体来制作最终的石膏模型。然后用实验室扫描仪扫描临时修复体。通过应用这种技术，可以将种植体的定位与咬合平面、牙齿轮廓和法兰联系起来。临床医生可以更有效地设计最终修复体，因为种植体的位置和牙齿的确切轮廓都包含在单个数字文件中。
