Prosthetic complications with mandibular bar-retained implant overdentures having distal attachments and metal frameworks: A 2- to 12-year retrospective analysis.

Statement Of Problem: Long-term reports on 2-implant-retained overdentures having metal frameworks and bars containing distal attachments are scarce.

Purpose: The purpose of this retrospective study was to evaluate prosthetic complications with 2-implant-retained mandibular overdentures with metal frameworks having either screw- or cement-retained cantilevered bars with distal attachments.
