Post and core systems, refinements to tooth preparation and cementation
D N J Ricketts1, C M E Tait2 & A J Higgins3
- There are many post systems available for retaining a core, the major difference depending on whether the post is active or passive.
- Active (threaded) post systems provide improved retention compared with passive (smooth-sided or serrated) posts however, they introduce stresses into the root and are associated with higher failure.
- Following post space preparation, certain post systems require further modifications to the tooth prior to post cementation.
- The choice of luting cement is indicated by the post type, whether metal or quartz fibre.
- Adhesive resin luting cements should not be used as a routine for cementing metal posts.

Abstract
With a plethora of post systems available, it is often difficult to decide which one to use. This is made more difficult by the fact that new posts are introduced before existing ones are fully evaluated in laboratory and clinical studies. This paper therefore describes the different post types and the main advantages and disadvantages of each. In addition, the choice of post system will influence whether further tooth preparation is required and will dictate which luting cement and core material are most appropriate. Whilst the choice of post will, for many dentists, be driven by personal preference and a history of clinical success, there are certain pit falls to avoid and these are outlined.
