Schnider N, et al. - An assessment was conducted of the clinical performance of one-piece, screw-retained implant crowns based on hand-veneered computer-aided design/computer-aided manufacture (CAD/CAM) zirconium dioxide abutments with a crossfit connection at least a year after the insertion of the crown. These screw-retained implant crowns were found to be a promising way of replacing the missing teeth in the anterior and premolar region. Findings did not reveal any failures of components and complications in the short term. Stable hard and soft tissue conditions were disclosed through the clinical and radiographic data.
