[Conserving silicoater treated surfaces with primers for use in adhesive prostheses]

To achieve permanent bond strength to enamel adhesive fixed partial dentures can be coated for example by a SiOx-C-layer followed by a silane primer (Silicoater system). Now and then these resin bonded restorations will be incorporated some days later. The object of this in-vitro-study was to investigate the possibility of preserving metal surfaces treated by the Silicoater system.

Metal surfaces coated in the described manner can be preserved by unfilled Bis-GMA-, PMMA-adhesives or a light curing opaquer (PMMA monomer) for later bonding without loss of bond strength. To cure the opaquer a special light curing apparatus is needed.
