title: Use of CAD/CAM to fabricate duplicate abutments for retrofitting an existing implant prosthesis: a clinical report.
abstract: Computer-assisted design/computer-assisted manufacturing (CAD/CAM) technology has been widely used in the field of dentistry. Among CAD/CAM custom abutments, zirconia abutments are becoming more popular due to their favorable mechanical and esthetic properties. However, recent review articles show that fractured zirconia abutments are a common prosthetic complication. In this clinical report, a 72-year-old man presented with a dislodged implant-supported fixed prosthesis because of fractured zirconia abutments. This clinical report describes a successful application of CAD/CAM technology to fabricate duplicate abutments, which were retrofitted to the existing prosthesis.
