The introduction of fiber posts has a great impact on the clinical procedures in restoring endodontically treated teeth. There has been continuous research on these products to modify the type of fibers as well as the shape of the posts. Endodontically treated teeth with severe coronal destruction have been a very common clinical procedure in the restorative clinical practice. This translucent fiber post is covered by a layer of light cured resin which allows for an individual anatomical modelling of the fiber post through its insertion in root canal with the aim of achieving a better adaptation and retention. In this way, the combination of two restorative materials i.e. composite resin and post will serve and behave as a replacement for the lost dentin structure. All the advantages determine the fiber posts as the first means of choice in restoring endodontically treated teeth.
