説明

In this study, the effects of storage temperature of ceramic primers on the bond strength of resin cements to the GN-1composite resin for the CAD/CAM system or GRADIA for the crown & bridge resin were examined.<BR>We used Porcelain Liner M and Lamina Bond Porcelain Primer as a ceramic primer. After receiving these primers, we stored them for20months at freezer or room temperature. The GN-1composite resin or GRADIA was treated with these primers. A polyvinylchloride ring mold was then placed on the primed surfaces. After this, the inside of the ring mold was filled with resin cement. The shear bond strength of the resin cement was measured, and29Si NMR observations of these primers were conducted.<BR>We did not observe any difference in the bond strength of the resin to the primed GN-1composite resin and GRADIA before and after storage of the Porcelain Liner M. However, when the Lamina Bond Porcelain Primer, which had been stored for20months, was applied, the bond strength decreased. The reduction in the bond strength obtained from storage at room temperature was greater than that obtained from the freezer storage. This was due to condensation of the silane coupling agent during the storage period.
