Integration between the phases of computer-based guided dental implant surgery can be used to optimize oral rehabilitation. Two new surgical guides prepared by using the 3D metal and polymer printing technology are presented for immediate implant loading and definitive fixed prosthesis construction in flapless dental implant surgery. Nine implants and 2 fixed prostheses were installed in 2 completely edentulous adult patients by using a metallopolymer surgical guide with a metal central bar attached to a polymer seal or a metal guide. Virtual planning was used to design the 3D printed surgical guides, which were then constructed by using selective laser sintering (SLM) and selective laser melting (SLS). The 3D printed surgical guides oriented the surgical placement of the implants and were welded to the abutments and attached to the denture framework. The technique allowed implants and prostheses to be installed on the same day.
计算机引导的牙科种植手术各阶段的整合可用于优化口腔修复。本文提出了两种新的外科导板，它们是使用 3D 金属和聚合物打印技术制备的，可用于无瓣牙科种植手术中的即刻种植体负载和最终固定修复体构建。通过使用带有金属中央杆的金属聚合物外科导板或金属导板，在 2 名完全无牙的成年患者中安装了 9 个种植体和 2 个固定修复体。使用虚拟规划设计了 3D 打印的外科导板，然后使用选择性激光烧结（SLS）和选择性激光熔化（SLS）进行构建。3D 打印的外科导板指导了种植体的手术放置，并将其焊接到基台上并连接到义齿支架上。该技术允许在同一天安装种植体和修复体。
