Abstract
- Purpose: The aim of this comparative in vitro study was to assess the bond strength and mechanical failure of carbon-fiber-reinforced composites against cobalt&ndash<br />chrome structures with ceramic veneering. Materials and methods: A total of 24 specimens (12 per group) simulating dental prosthetic frameworks were fabricated. The experimental specimens were subjected to a thermocycling aging process and to evaluate bond strength. All specimens were subjected to a three-point bending test to fracture using a universal testing machine. Results: The cobalt&ndash<br />chrome/ceramic group yielded a bond strength value of 21.71 &plusmn<br />2.16 MPa, while the carbon-fiber-reinforced composite group showed 14.50 &plusmn<br />3.50 MPa. The failure assessment reported statistical significance between groups. Although carbon-fiber-reinforced composite group showed lower bond strength values, the chipping incidence in this group was as well lower. Conclusions: The chrome&ndash<br />cobalt/ceramic group showed greater bonding strength compared to the carbon-fiber-reinforced composite<br />most of the fractures within the cobalt&ndash<br />chrome/ceramic group, had no possibility of direct clinical repair.
