title: Effect of an adhesive primer on the integrity of occlusal veneer-metal interface and wear of composite resin veneered restorations.
abstract: This study examines the influence of a metal-resin bonding agent on the wear rate of composite resin veneer. The specimens were prepared with a silver-based casting alloy and a light-cured composite veneering material. After application of repeated loading through a three-body wear testing device, the amount of wear was measured. The results showed no significant difference in wear between bonded and nonbonded specimens on the 1.5 mm areas of the veneer-metal interface. However, the bonded specimens exhibited significantly lower wear values at the veneer-metal interface. The use of an adhesive primer effectively enhanced the integrity of the occlusal veneer-metal junction.
