ABSTRACT:
A method of producing a dental post for use in restoring or stabilizing one or more teeth includes the steps of creating a hole in a tooth and obtaining a woven hollow rope which is mounted over a mandrel and inserted into the hole. The mandrel is withdrawn and the hollow rope is filled with a core-paste material. In a presently preferred embodiment, the woven hollow rope is woven in the form of a braid and the mandrel is in the form of a hollow needle attached to a syringe. In the preferred embodiment, the hollow rope is provided with a closed end and the needle is withdrawn while simultaneously filling the hollow rope with a core-paste material. The invention includes a new use for hollow woven rope, which is preferably hollow braided rope, in the formation of non-metallic fiber reinforced posts for use in dental application varying from dental posts used to support cores in root canal procedures to providing structural support for bridges, pontics and the like. The invention further includes the dental post constructed of a hollow woven rope which is injected with a core-paste material.
