Abstract:
The clinical durability of zirconia-based crowns in patients with bruxism over a 12-24 month period is of interest. Patients received zirconia crowns and were assessed for crown fracture, veneering chipping, marginal adaptation, wear and satisfaction. The crowns showed high structural integrity with minimal complications. Minor chipping of veneering porcelain was observed, but no fractures or debonding occurred. Thus, zirconia-based crowns maintained function and esthetics under high occlusal stress.
