dc.description.abstractThe restoration of seriously damaged teeth often requires an endodontic post. A number of different materials and shapes of dental posts have been manufactured, which leads to different mechanical behaviors. The currently used post systems frequently result in failure or fracture of the tooth, due to the difference between tooth and dentin mechanical properties. Recently, a bundle of fine individual posts made of reinforced fiberglass has been developed. This new approach is not a single-post and it can be spread apart, being individually distributed in the tooth canal. With this configuration, the fine posts can adapt to suit into any root canal anatomy. Biomechanical properties similar to the dentin are being reported as an advantage for the use of this new dental post. The purpose of this study is to understand if the bundle post introduces an improvement in the results of endodontic treatment, compared with the currently used post systems. This study was carried out using the finite element method to determine the influence of stress distribution on dentin, when these two different approaches are used. The results show that stresses at the dentin changed with the dental post used. The use of bundle post appears to better accommodate the developed stress, reducing the stresses in the tooth.pt_PT
