FIELD: medical engineering. SUBSTANCE: device has upper and lower frames with installation plates. The lower frame is rigidly fixed with one of ends on crossbar connecting two uprights. Incisor plate is mounted on supporting incisor pin with incisor mesinger. The other end is vertically and horizontally movably fastened by means of holder on one of upper frame ends. Frankfurter horizontal pointer is mounted on the same frame end. The other end of the upper frame is rigidly connected to a crossbar on both sides of which the left and right articulation units are placed. The units are rotatable relative to longitudinal crossbar axis, perpendicular symmetry axis of the upper frame. Curvilinear surface of the articulation insert groove of each articulation node is engageable with half-axle ball of ball support members. Locks are introduced into articulator design. The locks are mounted on articulation units to fix upper frame position relative to the lower one in occludator mode. The lower ends of the uprights are inclined to the horizontal plane. EFFECT: high accuracy of modeling. 4cl, 7 dwg |
