title: Precision porcelain jacket crown technique.
abstract: A simple technique for construction of an aluminous porcelain crown has been described. An aluminous core is fabricated without platinum foil on a ceramic refractory die and, when retrieved, serves as a coping on the master cast. The technique and accuracy of fit are illustrated with the fabrication of an aluminous porcelain crown on the Bureau of Standards' full-crown die.
