ADHESION IN DENTISTRY AND NEW APPROACHES OF ADHESIVE RESIN CEMENTS

One of the main factors affecting the success of the fixed prosthetic restorations, is a cementation process to hold the restoration on teeth. the last 15-20 years; adhesive resin cements have preferred in cementation of all-ceramics, laminate veneers, inlay-onlay restorations and adhesive bridges, because of the long clinical performance and less microleakage compared to conventional cements. compression and tensile strength of the resin cements are greater than the other cements. their elasticity modulus are lower than that of zinc phosphate cement, but greater fracture resistance and toughness. micro fillers in resin cements also increases viscosity, film thickness and the resistance to abrasion. the objective of this review was to evaluate dental adhesion, the clinical procedures of adhesive resin cements and their current development.
