Marginal and Internal Fits of Fixed Dental Prostheses Zirconia Retainers

null null Objectives null CAM (computer-aided manufacturing) and CAD (computer-aided design)/CAM systems facilitate the use of zirconia substructure materials for all-ceramic fixed partial dentures. This in vitro study compared the precision of fit of frameworks milled from semi-sintered zirconia blocks that were designed and machined with two CAD/CAM and one CAM system. null null null Methods null Three-unit posterior fixed dental prostheses...
