Dental structures are produced and attached in the tooth's root in similar fashion to inlays. They are used for root canal treated teeth in which large proportions of the hard tooth substances of the tooth crown have already been lost.

An imprint is produced with the help of an impression, on which the waxen or plastic structure is later produced. This modellation is then cast in precious metal, just like an inlay. The cast pin-stump structure is cemented into the prepared root. The cast pin-stump structure provides the tooth with more rigidity and is now prepared for the intake of the crown.
