Characterization of cast-to implant components from five manufacturers.

Statement Of Problem: Cast-to components are commonly used in screw-retained implant-supported restorations to produce precise fit. There is little information in the literature about the compositions and microstructures of commercially available products.

Purpose: The purpose of this study was to characterize as-received cast-to components from 5 manufacturers (Dentsply Friadent CeraMed, Lifecore Biomedical, Inc, Nobel Biocare AB, Institut Straumann AG, and Zimmer Dental).
