Abstract
Restoring endodontically treated posterior teeth is a critical challenge due to structural compromises following root canal treatment. This study evaluates the clinical performance of full-ceramic crowns (FCC), composite resin (CR) fillings, and ceramic inlays/onlays in posterior teeth using the World Dental Federation (FDI) criteria. A prospective cohort study was conducted involving 150 patients (194 posterior teeth), assessing functional outcomes such as fracture resistance, marginal adaptation, wear, and patient satisfaction over a mean follow-up period of 58.14 months (SD = 2.93). Statistical analysis revealed significant differences (p < 0.05) in long-term success rates among the three groups, with FCC demonstrating superior durability and marginal adaptation, while CR fillings provided a minimally invasive, cost-effective option with higher wear and marginal deterioration over time. Ceramic inlays/onlays offered a balance between structural conservation and durability, making them suitable for cases with moderate tooth structure loss. Patient satisfaction scores, as measured by the FDI criteria, were highest in the FCC group (mean score: 1.2 ± 0.4), followed by the ceramic inlays/onlays group (1.4 ± 0.5) and the CR fillings group (1.8 ± 0.6), with differences statistically significant (p < 0.05). These findings provide evidence-based recommendations for restorative material selection, emphasizing the need for personalized treatment planning based on clinical conditions and patient needs
