ABSTRACT:
A method of determining the position of an upper jaw cast and a lower jaw cast using a dental articulator provides a disposable plastic holder in the lower jaw cast and mounts it in a metal bracket bar fitted to the base of the articulator whose telescoping post allows adjustment of the height of the head above the base. A bracket bar mounted on the head and spring biased so that this bracket bar can move in a plane and can pivot about a horizontal axis receives another plastic disposable holder which can fit into a cavity in the upper casting. Once the castings are properly positioned, a hardenable composition can be cast into the recess to embed the holder in the upper casting.
