Abstract:
The purpose of the present study was to determine an effective surface preparation for the bonding of a gingival shade composite resin to a denture base resin. The flat surfaces of a heat-processed denture base resin were prepared in various ways. A highly filled gingival shade composite resin was applied and polymerized. Shear testing was performed in a universal testing machine, and the maximum fracture load values were determined. The application of chemically activated 4-META resin using the brush-dip technique was an effective surface preparation for the bonding of a gingival shade composite resin to a denture base resin.
