Mandibular Bar Attachment Retained Overdenture for Divergent Root Canals

Abstract

There are many bar attachments available for use today. The purpose of the bar attachment is splinting of the abutment teeth and retention, support of the prosthetic appliance. The bar retained overdenture fabricated without the custom-cast posts lacks retention; so to enhance the retention of the bar 
attachment, the custom cast posts are incorporated along with the copings of the bar. In most cases as root canals are divergent, the bar along with the posts cannot be made in the single casting because path of insertion and path of withdrawal is not possible. This clinical report describes a simple technique of
fabrication of bar attachment retained over denture with custom cast posts for divergent root canals.
