The repair of a fractured porcelain surface with a resin composite was investigated. The effects of applying an opaque resin to porcelain surfaces, which were silanated by a ceramic primer from a repair kit or by an experimental silane coupling agent, were studied. The porcelain surfaces were silanated for 10 sec and 60 min. Three types of adherents were evaluated: opaque resin with light irradiation (OWL), opaque resin without light irradiation (ONL), and no opaque resin (NAO). The shear bond strengths of the resins to the porcelain surfaces were measured before and after thermocycling. The maximum shear bond strength (6.7 MPa) after thermocycling was observed when the silanating period of the ceramic primer was 60 min. The opaque resin had no effect on the bond strength. Moreover, the bond strength obtained with the experimental silane coupling agent was found to be reduced by only 2 MPa, even after thermocycling.
