A flexible post for endodontic or reconstructive tooth therapy having a modulus of elasticity which is less than or equal to that of dentin of 18 GPa (giga Pascals). The present invention is preferably made of fiberglass fibers, such as optical fibers, medical grade optical fibers, other medical grade fibers or other fiberglass composite fibers. The micro filaments of the present invention are treated to impart flexibility to each fiber. The fibers are twisted by twisting on other non-axial arrangements of the fibers to impart strength to the unit post. This allows it to function as a permanent post in a tooth. The dental post is flexible and the post conforms to the natural curved contours of a root canal to reduce machining of the tooth and mechanical weakening of the tooth structure.
A dental reinforcement member for endodontic and reconstructive pin therapy comprising a bundle of fibers having at least one non-axially aligned flexible fiber therein, said fibers extending in a resin binder from a coronal end to an apical end of said post.
A dental reinforcement member for endodontic and reconstructive pin therapy comprising a bundle of non-axially aligned flexible fibers in a resin binder wherein said fibers include a twisted bundle of linearly extending fibers.
A dental reinforcement member for endodontic and pin reconstructive therapy comprising a prefabricated cylindrical, parallel sided flexible fiber for extending from an apical end to a coronal end of a tooth, said post being a unitary bundle of non-axially aligned flexible fibers in a resin binder.
