Abstract: A face place assembly unit is provided for fixing a dental cast to one or both of the frame members of a dental articulator. The face plate is multidirectionally positionable relative to the frame member of the articulator, to provide for accurate positioning of a dental cast mounted to one of the frame members relative to a dental cast mounted the other of the frame members. In one embodiment, the face plate unit is provided with a position fixing assembly which allows the dental cast to be accurately positioned relative to a frame member of a dental articulator and then fixed in such relative position. The assembly can then be removed from the articulator and reconnected thereto while maintaining the position of the dental cast relative to the frame member of the articulator to which it was mounted.
