Etched-porcelain resin-bonded full-veneer crowns: in vitro fracture resistance.
A recent study showed that both anterior and posterior glass ionomer-bonded crowns were significantly weaker than natural teeth. However, the fracture resistance of resin-bonded anterior crowns exceeded the strength of their size-matched controls. The three cement types were significantly different, with the average strength for Gluma, a-bonded crowns being the highest, then the Scotch-bond, b-bonded crowns, while Ketac Bond, c glass ionomer cemented crowns were the weakest. This pilot study indicates that the resin-bonded etched-porcelain full-veneer crowns are almost as strong as natural teeth and significantly stronger than glass ionomer-bonded crowns.
