A Predictable Precision Cast for Multi-unit Screw-retained Implant Prosthesis: Rationale and Technique

Abstract

The aim of this article is to describe a technique derived from the premachined cylinder luting technique with the goal to predictably fabricate a highly precise master cast. An impression can be taken directly at implant level or, with some technique modification, at the abutment level. Concurrently, multiple techniques can be employed to fabricate the final framework with the assurance that a framework that fits the cast will fit in the mouth. This predictability improves the workflow of the restoring dentist and laboratory technician since multiple framework try-ins and adjustments are eliminated.
