Abstract

Zirconia crowns are widely used in dentistry due to their strength and biocompatibility. However, their surface limits bonding efficiency. Therefore, it is of interest to assess the effect of bioactive glass coating on fatigue resistance of zirconia crowns. Coated crowns showed significantly higher fatigue resistance (1150 ± 45 N) compared to uncoated ones (950 ± 50 N, p < 0.05). SEM analysis confirmed reduced microcracks and better stress distribution in coated crowns. Bioactive glass coating enhances the clinical durability and performance of zirconia crowns under functional loads.
