ABSTRACT:
This dental casting apparatus includes a track, and a tray. The track has an inner and an outer track wall and a first and a second end portion which combine to define a chamber. A hardenable wet stone material is positionable within the chamber of the track. After the stone is allowed to harden within the track, a sharp knife cuts through the stone and the track to form a plurality of dies. The tray has an inner tray wall and outer tray wall which combine to define a recessed portion. The individual dies are positionable within the tray recessed portion, and are readily engageable and disengageable therefrom. The dental casting apparatus also includes a mechanism for securely retaining the dies to the tray in such a manner that each die can be individually removed from the tray without disengaging adjacent dies.
