Use of a Copper Band to Make Resin Cores in Endodontically Treated Teeth Lacking Coronal Structure

Oper Dent. Sep-Oct 2015;40(5):458-61. doi: 10.2341/14-206-T. Epub 2015 Jul 7.


This article describes the use of a copper band as a matrix to build up resin cores in endodontically treated teeth that have a partially subgingival margin. The copper band is adjusted to the contour of the remaining dental structure and extends beyond the margins to ensure complete isolation in order to provide a matrix to fabricate a core.
