The effect of variations in bonding procedure on fracture resistance of dentin-bonded all-ceramic crowns.
This in vitro study investigated the effect of dentinal bonding and ceramic etching procedures on the fracture resistance of all-ceramic crowns. These results were compared with the fracture resistance of similar crowns placed with a nonadhesive conventional cement. All results indicated that superior fracture resistance was obtained when dentinal bonding was incorporated into the luting procedure together with etching of the ceramic fitting surface and the use of resin-based luting material. The fracture resistance of specimens luted with such a procedure was significantly greater than that of specimens in which a conventional nonadhesive cement was used.
