Abstract
The object of this work is to determine whether the FRP(fiber reinforced plastics)frame, which was made from visible light cured prepreg, can be clinically used for crown and bridge resin Bonding strength of crown and bridge resins to FRP frame was about 100kgf/cm2. Zinc phosphate cement, polycarboxylate cement and glass ionomer cement hardly adhered to the FRP flame.However, bonding strength of resin cement to FRP frame was high and that of Super Bond C & B was about 240kgf/cm2. The FRP frame fitted perfectly the stone cast of abutment tooth, and deviation at margin of the stone cast was scarcely observed.The FRP frame had various properties, such as simplicity of use, repair, adjustment and coloring, superior to those of metal frame.Application of the FRP frame crown and bridge resin made opaque resin and retention beads unnecessary These results suggest that the FRP frame can be used clinically for crown and bridge resin.
