PROBLEM TO BE SOLVED: To provide a joint structure of an articulator that can be easily divided into upper and lower parts while being accompanied by the reproduction of temporomandibular joint motion.SOLUTION: A magnet is attached to a joint head of a lower frame and a joint condyle path part of an upper frame opposite to it is formed by a magnetic metal plate to enable the articulator to reproduce the rotation and the sliding motion of the joint head using magnetic force. Also, a condyle path angle guide plate is installed at the front of the center of an upper-frame right/left joint condyle path, and a condyle path angle adjusting screw is attached to the front of the center of a lower-frame right/left joint head, whereby the motion of the temporomandibular joint is reproduced using three points including right and left joint heads and the screw, and removal of the upper and lower frames is also facilitated.COPYRIGHT: (C)2012,JPO&INPIT【課題】顎関節運動の再現を伴い上下を容易に分割できる咬合器の関節構造を提供する。【解決の手段】下弓の関節頭に磁石を取り付け、対する上弓の関節顆路部は磁性金属板によって磁力を応用した関節頭の回転及びスライド運動を咬合器で再現可能にするとともに上弓左右関節顆路の中央前方部に顆路角度誘導板を設置し、下弓左右関節頭の中央前方部には顆路角度調整ねじを取り付けることにより左右関節頭と3点による顎関節の動きを再現させなおかつ上下弓の取り外しも容易となる。以上を特徴とする咬合器の関節構造にする。【選択図】図1
