Resin cements are adhesive luting materials used to bond indirect restorations — crowns, bridges, veneers, inlays, onlays, and CAD/CAM restorations — to prepared tooth structure or implant abutments. Available in light-cure, self-cure, and dual-cure formulations, resin cements are selected based on restoration translucency, thickness, and location, since light-cure cements require adequate light penetration while dual-cure cements ensure complete polymerization beneath opaque or thick restorations. Strong adhesive bonding from resin cements enhances retention and can reinforce the strength of thin ceramic restorations, making cement selection an important step in the final seating protocol.
