![]() All implant components were composed of 2 distinctive parallel-band constituents containing gold, pal-ladium, and platinum. Mean values and standard deviations were determined for the composition and Vickers hardness data. Overall Vickers hardness (500-g load) and Vickers hardness of the 2 primary microstructural constituents (10-g load) were measured. Elemental analyses (EDS) were performed using an energy-dispersive x-ray spectrometer coupled to the SEM. Secondary (SE) and backscattered electron (BSE) images were collected to investigate the variations in surface topography and composition, respectively. Two components from each manufacturer were mounted in metallographic resin, sectioned into quarters, remounted, wet polished with alumina abrasives, cleaned by ultrasonic agitation in distilled water, etched with aqua regia solutions, and carbon coated for scanning electron microscope (SEM) observation. The purpose of this study was to characterize as-received cast-to components from 5 manufacturers (Dent-sply Friadent CeraMed, Material and methods. There is little information in the literature about the compositions and microstructures of commercially available products. ![]() Cast-to components are commonly used in screw-retained implant-supported restorations to produce precise fit. There should be no clinical concern about biocompatibility when using any of the 5 noble cast-to components evaluated with noble casting alloys for screw-retained implant-supported prostheses.
