Durability of Bond to Sintered Porcelain of Four Ceramic Bonding Systems

Abstract

The purpose of the current study was to evaluate bonding performance of ceramic bonding systems consisting of a two- or three-liquid silane agent and a resin-based luting material. Sintered porcelain disks (VMK 68) were air-abraded with alumina, and bonded with one of the four bonding systems: Clapearl Bonding Agent and Clapearl DC; Clearfil Porcelain Bond and Panavia 21; Porcelain Liner M and Super-Bond C&B; and Tokuso Ceramics Primer and Bistite Resin Cement. Specimens were either thermocycled (100, 000 cycles) or uncycled, and shear bond strengths were determined. With the exception of the Clearfil Porcelain Bond -Panavia 21 system, post-thermocycling bond strengths of three systems were comparable. Although the Tokuso Ceramics Primer -Bistite Resin Cement system recorded the greatest pre-thermocycling bond strength, reduction after thermocycling was remarkable.
