Outline of Final Research Achievements

The fracture resistance of single-tooth implant-supported zirconia-based indirect composite-layered molar crowns is comparable to that of zirconia-based all-ceramic restorations. Framework designs influenced on the fracture strength of implant-supported zirconia-based composite-layered molar crowns. All types of implant-supported zirconia-based prostheses tested after artificial aging have the potential to withstand clinical chewing forces in posterior applications.
