ABSTRACT:
A two-component, dental post system uses two components to both improve the fit of the post to the tooth and increase retention of the post. This post system has a threaded inner post that is screwed into the apical portion of the canal and an outer sleeve that is screwed into the coronal portion of the canal with threads whose handedness is opposite to those on the inner post. When the two components are bonded together at the top by dental cement or resin, the opposing threads on the two components resist rotational forces in both directions and thus increase retention. In addition, this dental post system can be removed if necessary for further treatment of the tooth by shearing or cutting the cemented top portion of both components and then unscrewing the components one at a time.
