Several factors contribute to distortion of implant prostheses during fabrication and could prevent passive, accurate adaptation between implants and implant frameworks. The misfit between implants and restorative components may be significant and possibly lead to biologic or mechanical complications. The aim of this article is to describe a laboratory luting technique used to lute implant cylinders to metal frameworks in implant prostheses. This technique provides accurate, passive fits. According to this technique, titanium implant cylinders provided with corresponding external castable cylinders are used. Implant cylinders are screwed into the analogs in the master cast while the castable cylinders on top are splinted together using castable resin to realize a castable resin pattern. After casting, the framework is adjusted and cemented to the titanium cylinders on the master cast. Due to its ease and quickness of use and clinical efficiencies, this technique is deemed particularly useful in immediate loading rehabilitations.
有几个因素会导致种植修复体在制作过程中变形，并可能妨碍种植体与种植体支架之间实现被动、精确的适配。种植体与修复部件之间的不匹配可能很严重，并可能导致生物或机械并发症。本文的目的是描述一种实验室粘结技术，用于将种植体柱粘结到种植修复体的金属支架上。该技术可提供精确的被动适配。根据该技术，使用配有相应外部可铸型柱的钛种植体柱。将种植体柱拧入主模型中的代型上，同时使用可铸型树脂将顶部的可铸型柱固定在一起，以形成可铸型树脂模型。铸造后，调整支架并将其粘结到主模型上的钛柱上。由于其使用简便快捷且具有临床效率，该技术在即刻负重修复中被认为特别有用。
