Hybrid Resin Composite vs. Hybrid Ceramic Onlays for Restoring Carious Molars
The goal of this clinical trial is to compare the clinical performance of hybrid resin composite and hybrid ceramic onlays in restoring carious molars. It will also evaluate the wear resistance of both materials. The main questions it aims to answer are:
* Does the hybrid resin composite or hybrid ceramic onlay perform better in clinical settings over time? * How much wear occurs in each type of onlay over 18 months?
Researchers will compare SHOFU Ceramage (hybrid resin composite) to SHOFU Block HC Hard(hybrid ceramic) to see which material performs better in restoring molars with extensive caries.
Participants will:
* Receive either a hybrid resin composite or hybrid ceramic onlay for their molar cavities. * Visit the clinic for checkups at baseline, 6 months, 12 months, and 18 months. * Undergo visual assessments of their restorations and quantitative wear analysis during follow-ups.
