The objective of this article was to illustrate the digital process in the custom fabrication of metallic mini-implant supported appliances. An implant-supported appliance was produced for a patient using a CAD-CAM procedure without a physical impression or a printed model. The work flow consisted of mini-implant insertion into the palate, recording an intraoral digital scan, digital design with incorporation of a scanned expansion mechanism, direct 3-dimensional metal printing via laser melting, laser welding of the hyrax mechanism, insertion, and activation of the appliance. The favorable clinical outcome demonstrated that this procedure is an efficient and viable method for constructing an implant-supported palatal metallic appliance.
本文旨在阐述金属微型种植体支抗修复体的数字化定制流程。通过 CAD-CAM 技术，我们为一位患者制作了一款种植体支抗修复体，整个过程无需取模或制作印模。其工作流程包括将微型种植体植入上颌、获取口内数字化扫描、结合扫描扩张装置进行数字化设计、通过激光熔化直接进行三维金属打印、对 hyrax 矫治器进行激光焊接、植入并激活修复体。良好的临床效果表明，这种方法是构建种植体支抗腭部金属修复体的有效手段。
