Over the years, dentists in Taiwan have conducted numerous studies on Franz 3D-printed zirconia porcelain dental restorations, including crowns, veneers, inlays, onlays, and brackets. These studies have found that 3D-printed crowns effectively conceal discolored abutments while providing exceptional comfort and aesthetics. In certain applications, such as veneers, inlays, and onlays, Franz 3D-printed restorations have demonstrated superior precision and efficiency compared to CAD/CAM-milled alternatives. Below are images from case studies, released with patient consent, for publication.
