Abstract

Low bond strength between tooth structure and restorative ceramic material is a major cause of ceramic fractures or failures. Prebonding measures performed on pressable ceramic material were evaluated and the different shear bond strengths obtained by each method were tabulated. The three individual groups were subjected to 9% hydrofluoric (HF) acid gel for 0, 1, and 5 minutes. The different acid-etched time groups were chemically treated with silane coupler alone, silane coupling agent with bonding agent, and bonding agent alone. The silane coupling agent produced the highest bond strength between the composite structure and the pressable ceramic restorative material. High bond values were achieved by etching the porcelain for one minute. The use of the silane coupling agent with a one minute 9% HF acid etch yielded the greatest bond strength.
