Injectable Resin Composite Versus Dual-cured Resin Cement for Cementation of Indirect Onlay Restorations

The introduction of injectable composites, according to available literature, offers a simple and efficient solution for the cementation of veneers. This versatile, injectable restorative composite unites easy handling, high physical properties and excellent aesthetics. Generally used as a restorative material, it can also be used for the cementation of veneers and some inlays/onlays, thus considered as good alternative to preheated composite.

Resin cements are widely used due to their strong adhesion, and compatibility with various restorative materials, including ceramics and zirconia. They bond to enamel and dentin through functional monomers such as MDP, and 4-META, forming a stable hybrid layer. Based on their bonding mechanism, resin cements are classified as adhesive or self-adhesive, while their polymerization method -chemical, light, or dual-cure-allows for versatility in clinical applications
