Clinical performance of two different adhesive strategies for metal-ceramic cracks repairing and related <i>in vitro</i> study

To evaluate the bonding reliability of a universal adhesive compared to commercial ceramic repair system for metal-ceramic cracks. In vitro part: sixty specimens with porcelain, metal and porcelain-metal substrate were fabricated. Half bonded by Singlebond Universal Filtek Z350 resin composite. The other processed Ceramic Repair N. Shear bond strength was tested. vivo forty patients fractured porcelain-fused-metal restorations involved. repaired Z350. restored mean observation period 65 weeks. Results showed ranged from 13.97 MPa 15.85 using two different on no statistical difference. There difference between in survival rate according Kaplan-Meier analysis. had similar performance system.
