Observational analysis shows zirconia posts have better initial bond strength, while fiber posts indicate greater long-term stability under thermocycling.
The comparative performance of zirconia and fiber posts in endodontically treated teeth under simulated oral conditions, show significant differences in fatigue resistance and bond strength degradation. Zirconia posts initially exhibited superior bond strength; fiber posts maintained better long-term stability under thermocycling and mechanical loading conditions, with implications for clinical longevity and restoration success rates.
