Cast dowel and core

The cast dowel and core (DandC) technique has been used for a long time and still being used today when prefabricated fi ber post prevails. Several in vitro and in vivo studies have shown that prefabricated fi ber posts and core build-ups are doing better or similar to cast D&Cs. However, the comparison between prefabricated fi ber posts and cast DandCs should be done fairly in terms of the amount of remaining tooth structure, cementation/bonding techniques used, and clinical expertise of the researchers, among others. This chapter will focus on (a) the indications for cast DandCs over the prevalent prefabricated fi ber posts and composite core build-ups, (b) factors affecting the long-term success of cast DandCs, (c) two different clinical techniques (direct pattern and indirect impression) and respective sequences to fabricate a cast DandC and subsequent full-coverage restoration, and (d) the cementation/ bonding of cast DandCs as well as the full- coverage restoration.
