Summary

Marginal integrity is considered the main essential part of indirect restorations and any discrepancy after cementation and poor marginal fit can lead to microleakage, marginal discoloration, dissolution of cement and secondary caries. The type of cement used plays an important role and can govern the amount of augmentation in discrepancy after cementation.

Although resin cement is still the gold standard luting agent for the cementation of all indirect restoration, it lacks some properties that may be available in the restorative resin composite such as higher filler loading, higher mechanical properties and wear resistance.

may have been the first to propose the use of restorative, flowable resin composite as a luting agent for ceramic inlays. These authors demonstrated that with respect to polymerization rate, there were no advantages of dual curing-resin compared to light curing only. In addition, the overall handling of the light-curing flowable restorative resin composite was judged to be easier than that of the dual cured material. The same conclusions were drawn by Kramer and franken Berger who added that less luting resin composite overhangs were found with the light polymerized composite-resin because the clinician has more time for excess removal prior to polymerization. The claimed further potential advantages of using restorative rein composite as a luting agent is their resistance to wear which proved to be superior to resin cements

Interventions

OTHER

Injectable restorative resin composite

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. (Alajrash MM et al., 2020)

OTHER

Dual cured resin cement

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
