Hydrofluoric acid etching versus self-etching glass ceramic primer: consequences on the interface with resin cements

Abstract

The long-term survival of aesthetic restorations remains a challenge dependant on successful and reliable bonding of ceramics to dental substrate. In order to improve resin cement bonding to ceramics, various surface treatments favoring micromechanical retention and chemical bonding were recommended [1,2]. According to CekikNagas, the composition of the ceramic determines the best surface treatment to be applied [3].
