    Abstract: The invention provides an articulator for the dental art comprising an upper member articulated on condylar balls integral with a lower member, the balls being engaged in housings of the rear hub of the upper member. Two transverse rods, actuated by a control means engaging between the inner ends of the rods, are urged back towards the condylar balls and pass through the BENNETT wings. The control means comprises several different spacing zones for providing variable spacings between the rods which, either come into abutment against the balls to maintain the upper member in the centered position or they free the balls so as to allow an immediate lateral displacement.
