New Technique for the Use of a Precision Attachment in the Fabrication of a Cast Crown/Core and Post Unit: Procedures and Case Report

Abstract

A case report of a prefabricated cast post system, Flexi-Cast, is presented. This tech-nique provides maximium retention of the post in the root and crown to a core by incorporation of a prefabricated split-shank threaded post with an attachment sleeve. Clinically this appears to be a simple predictable technique for the fabrication of a crown/core as a single unit.any approaches for the fabrication of a crown,
