Objective To evaluate the effects of all-ceramic veneers in clinic fabricated by computer aided de-sign/computer aided manufacturing(CAD/CAM) system and veneered with Vita VM9.

The opaqueeffect of 3 resins covering dental alloys in the all-ceramic treatment;

Objective To compare the retention of selected cores to all-ceramic posts in post-and-core system,in which the ceramic core was combined with the post by direct sintering,adhering,and the composite resin core was formed onto the post.

The all-ceramic restorations have been widely accepted because of there superb and natural aesthetic effects, and the importance of the aesthetic properties of implant superstructures has been more and more emphasized.
