Monolithic zirconia outperforms metal-ceramic in mechanical reliability for single implant crowns but lacks long-term validation

Monolithic zirconia crowns demonstrate superior mechanical reliability and fewer technical complications but have aesthetic limitations compared to metal-ceramic crowns. Biologic outcomes were comparable between both materials. Clinicians should weigh mechanical durability versus aesthetic demands when selecting implant-supported restorations. Further long-term studies are recommended to validate these findings.
