Abstract(s)
The 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.
