Ideal tooth preparation and interim prostheses are critical to a predictable esthetic and functional outcome in the treatment of full-mouth-fixed restorations. During the treatment stages, multiple procedures need to be considered for a successful and predictable outcome. These include the parallel preparation of multiple abutment teeth followed by the relining of the interim prostheses. The purpose of this article is to describe a technique to simplify tooth preparation and facilitate subsequent insertion of a complete-arch-fixed interim prosthesis using vacuum-formed templates.
