Abstract
The main member of the Dental Articulator is a unitary structure of first and second bodies attached by legs. Each of the legs has a self-hinge. The body each has a socket which receives a ball. The balls each has a tapered spline which engages in the corresponding mold recess in a dental cast. The balls are clampable in the sockets when the dental casts are in proper relative position. The self-hinges permit repeatable opening and closing of the dental cast.
