title: Effect of no ferrule on failure of teeth restored with bonded posts and cores.
abstract: This study investigated how the absence of a ferrule affected the failure load of teeth that had been restored with bonded fiber posts and resin cores. There was a significant difference (p < 0.001) between the ferrule and nonferrule groups' load to failure. For the ferrule group, root fracture was the predominant mode of failure; in the nonferrule group, debonding failures were predominant.
