Abstract
Implant superstructure cementation has been demonstrated to be superior clinical significance. However permanent cementation of all ceramic restorations completely impair it’s retrievability and would also risk loosing the implant abutment. The aim of this study was to investigated the influence of cement types on fracture resistance of zirconia copings when bonded to zirconia implant abutments.
