Abstract

Implants supporting a fixed prosthesis may fail leaving unfavorable implant distribution for a fixed prosthesis. This clinical report illustrates a treatment option for converting a failing fixed prosthesis into a mandibular complete overdenture by using a portion of the existing fixed implant prosthesis. The use of a resilient liner to retain a converted mandibular overdenture framework provided satisfactory results in the first year of clinical use.
