Cement-retained, implant-supported restorations have advantages over screw-retained restorations, but retrievability can be a problem. By using computer-aided design and computer-aided manufacturing (CAD/CAM) technology, a working cast or mouth can be scanned, and a definitive record of the screw hole can be made in 3 dimensions and saved as a file. This information includes not only the position of the opening of the screw hole but also its angulation and orientation, which can be retrieved if required. (J Prosthet Dent 2013;109:57-60)
