<p>An articulator to reproduce more exactly an actual positional relation between the upper and lower jaws of a patient and the center of opening/closing motion of said jaws at a place outside the patient's oral cavity, in which the distance between the model of upper jaw and a supporting shaft acting as a false joint and that between the lower jaw and said joint are variable. The articulator comprises: a setting frame (3) having a base plate (2) slidably fixed thereto; another setting frame (5) having a base plate (4) slidably fixed thereto; and a supporting member (7) for turnably connecting two setting frames (3 and 5) to each other. A position in which the models are fixed to the setting frames can be moved with respect to the supporting shaft acting as a false joint, whereby a prosthetic appliance having the center of opening/closing motion of the upper and lower jaws varied as desired can be fabricated. <IMAGE></p> |
