抄録

In this study, the effect of the roughness of porcelain surface on the bond durability of resin to the silanated porcelain surface was examined, since the manufacturer recommends grinding the fractured porcelain surface by a diamond point to roughen the porcelain surface before repairing fractured porcelain using resin composite. Furthermore, the effects of the silanating period of the roughened porcelain surface and the application of bonding agent on the bond durability were studied.<BR>The bond durability of the resin to the silanated porcelain surface differed between porcelain surfaces prepared by grinding with #100and #1, 000. The roughness of the porcelain surface affected the bond durability of resin composite. This result clearly suggests that grinding of the fractured porcelain surface by a diamond point provides noticeably higher bond durability than that by the # 100grinding.<BR>On the other hand, the extension of the silanating period from10seconds from 60 minutes increased the bond durability. However, the obtained bond durability was the same as that obtained when the resin composite was directly applied to the silanated porcelain surface without any application of bonding agent. The application of bonding agent to the silanated porcelain surface did not improve the bond durability.
