Abstract
The new type resin which composed with crosslinked monomer and a prepolymerized composite filler, a so-called organic filler, improved remarkably hardness and abrasion resistance of crown and bridge resins. In addition, an adhesive opaque resin containing 4-META could bind firmly a resin to a metal frame without any mechanical retentive devices. In this study, the fracture strength of resin veneered crowns fabricated with these new materials was compared with that of the bonded porcelain veneer crown by impact and peel test. The results showed the resin veneered crowns was superior to the bonded porcelain veneer crowns about impact and peel resistance.
