Abstract
A cover for a working cast makes it extremely easy to mount and dismount a working cast to and from an articulator, improves workability, and keeps the working cast as pollution-free as possible. An articulator is also proposed. The articulator has a base and a support member each carrying a rotatable and pivotable retainer plate. Each retainer plate can be fixed in position by turning a knob. Each retainer plate has a magnet plate on its outer surface. On the other hand, a base portion of a master model having a tooth portion is kept covered with the cover when molded. The cover has on its bottom surface a magnet plate. By magnetic attraction between the magnet plates of the cover and one of the retainer, the master model can be mounted on the articulator. On the other hand, a tooth portion of an antagonist model is fixed to a base member. The antagonist model is mounted on the articulator by magnetic attraction between a magnet plate provided on the bottom of the base plate and the magnet plate on one of the retainer plates.
