A metal, ceramic, or fibre-reinforced peg or dowel used to attach an artificial crown to the root of a natural tooth. A metal post may be either cast or preformed; preformed posts are either tapered or parallel-sided, and may have a thread for additional retention which enables them to be screwed into a prepared post hole. Examples of fibre-reinforced posts are carbon-fibre and glass-fibre. Posts are retained using a luting cement.
