Abstract
The number of single-tooth implants has been steadily increasing in recent years, so that their superstructures have to prove themselves for a wider range of patients than ever in terms of longevity, esthetics, and function. The combination of CAD/CAM technology and new restorative materials especially enables innovative and efficient therapeutic approaches for implant-supported single-tooth restorations. This article describes, classifies, and evaluates so-called hybrid abutments and hybrid abutment crowns as possible restoration alternatives, some of which-depending on the indication and workflow-promise fully digital, model-free working. New prosthetic concepts also bring the controversial discussion of screw-retained versus cemented superstructures into the spotlight. Another aspect is addressed to the question of the biomechanical behavior of monolithic fabricated hybrid abutment crowns in particular and the best possible failure mode. Thus, implant-supported single-tooth restorations on titanium adhesive bases will be critically discussed, and the possible advantages and success factors will be weighed against limitations and potential sources of failure.
