Quick Reference

The central part. A heavily broken-down tooth can be built up in either amalgam (amalgam core) or composite ( resin composite core) to replace missing tooth substance and form a rigid and retentive base for a crown restoration. The core may be retained by mechanical undercuts, pins, or adhesive systems. The core may be made of cast metal (cast core) and extend into the root of an endodontically treated tooth for retention and then cemented prior to the placement of a crown (cast post and core).
