The Performance of Posterior Partial Coverage Coronal Restorations Luted With Two Differrent Systems.

This study explores an alternative approach using a pre-heated restorative resin composite as a luting material of partial coverage restorations on upper and lower posterior teeth. It will follow a split-mouth design with 60 participants selected based on strict criteria. Assessment at 6 months and 1 year post-delivery utilizes a modified model of USPHS criteria, evaluating retention, color match, marginal discoloration, secondary caries, anatomical form, marginal adaptation, and surface roughness. The null hypothesis: The use of preheated resin composite for cementing partial coverage restoration will not result in significantly superior clinical performance when compared to that after using dual-cure resin cement.
