Retrofitting implant overdenture attachments: A clinical report

The remake of implant-overdenture prostheses on preexisting implants can present the clinician with a challenge, especially when the prosthetic components used initially cannot be replaced. The difficulty of remaking the prosthesis may be further increased by implant attachments designed to be cemented to the implant itself--a feature that complicates future replacement. This clinical report describes the restoration of worn implant attachments using retrofit components.
