ABSTRACT:
A dental articulator wherein each of two pivotally joined arms carries a plate-like first support and a shallow trough-shaped second support which confines a mass of synthetic thermoplastic material serving to couple the second support to the first support. If the position of the second support relative to the first support is to be adjusted, the mass of thermoplastic material is plasticized so that such mass then acts not unlike a universal joint which enables the two supports to assume any one of an infinite number of different positions relative to each other. Each second support can carry a dental model and can be provided with a magnetic insert to attract a complementary magnet of the model.
