The addition of an adhesive composite resin to the same material: bond strength and clinical techniques.
The addition of a chemically adhesive composite resin to a restoration of the same material may be evaluated by the bond strength. This was determined after no contamination and after momentary (30 seconds), short-term (7 days), and long-term (3 months) contamination under various conditions. The momentary contamination was not removed by spray-washing the glossy surface that set under a matrix. Removing the glossy surface reduced the bond. The momentary contamination was removed by the etchant whereas the longer contamination was removed only by surface reduction. The application of etchant and bonding agents significantly strengthened the bond to the reduced surface. According to the directives drawn from this investigation, the clinical techniques were illustrated for a large restoration, a subgingival proximal restoration, repair of an open proximal contact, and repair of a worn restoration.
