The Bond Strength of Composite Laminate Veneers

Journal of Dental Research (Impact Factor: 4.14). 11/1985; 64(10):1261-4. DOI: 10.1177/00220345850640101701

An in vitro model has been developed simulating a composite laminate veneer restoration, along with methods to mimic the environmental conditions to which these restorations are subjected in vivo. Fifty composite laminate specimens were prepared: Ten were left untreated as controls, and 40 were exposed to simulated environmental conditioning. The tensile bond strength of the veneer-to-composite interface was significantly reduced by both thermal and humidity cycling, which may explain the increasing prevalence of marginal failure and staining which occurs as these restorations age in vivo.
