Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Secondary Objectives are:
1. To compare the incidence of restoration failures between the two materials
2. To assess marginal adaptation and marginal discoloration over time
3. To evaluate wear of opposing enamel quantitatively
4. To compare surface texture, color match, and luster between materials
5. To determine patient satisfaction with both types of restorations It will be a randomized, controlled, double-blind clinical trial with 1:1 allocation ratio.
