A evolução dos retentores intra-radiculares: revisão de literatura

Abstract

After endodontic therapy, it´s necessary to give back the tooth function, reintegrating it into the masticatory system by an adequate restorative procedure. The main objective of the intraradicular retainer is to provide a retaining to the core fill in the coronal portion of which will receive the prosthetic crown. Therefore, for the clinical success of the treatment, a series of biomechanical requirements are necessary in order to ensure the longevity of the restoration and to increase the tooth rate of survival. Among these biomechanical factors are the length and diameter of the pin, shape of the retainers, the amount of remaining tooth structure, cementing agent and distribution of forces and stresses at the tooth root. The objective of this study was to review the literature about the characteristics of endodontically treated teeth and the evolution of the intraradicular retainers. For this purpose, a survey was conducted in the databases using the keywords health: endodontic treatment, intraradicular pin, pin types, advantages, disadvantages.
