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