Abstract

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.

Description

そのために、次のような問題点があった。
（イ）額関節の３次元的運動の再現を伴い上下容易に分割できる構造がなかった。
本発明は、これらの問題点を解決するためになされたものである。Therefore, there are the following problems.
(A) There was no structure that could be easily divided up and down with the reproduction of the three-dimensional motion of the forehead joint.
The present invention has been made to solve these problems.

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構造にする。
以上を特徴とする咬合器の関節構造である。A magnet is attached to the joint head of the lower arch, and the joint condyle of the upper arch can be recreated with the articulator by using a magnetic metal plate to apply the magnetic force to the joint head and the condylar path of the upper arch. A condylar path angle guide plate is installed in the central anterior part, and a condylar path angle adjusting screw is attached to the central anterior part of the left and right joint heads of the lower bow to reproduce the movement of the temporomandibular joint and the temporomandibular joint with three points. Make the structure easy to remove.
The articulator joint structure is characterized by the above.

従来のような複雑な構造がなくなり関節の自由運動も阻害されることなく、咬合器の取り扱いが容易かつ明快であるとともに作業効率も向上する。Since the conventional complicated structure is eliminated and the free movement of the joint is not hindered, the articulator can be handled easily and clearly and the work efficiency is improved.

以下、本発明の実施の形態について説明する。
（イ）上弓左右関節顆路部に磁性金属板を取り付ける。
（ロ）上弓左右関節中央前方部に顆路角度誘導板を設置する。
（ハ）下弓左右関節頭に磁石を取り付ける。
（ニ）下弓左右関節頭中央前方部に顆路角度調整ねじを設置する。
本発明は以上のような構成で、（イ）、（ハ）の磁力による吸着力で上下を連結させ、（ニ）の顆路角度調整ねじの調節により顆路角の調節と（ロ）の顆路角度誘導板で顆路の誘導を行えるとともに３点で咬合を安定させ磁力の範囲内において関節の自由運動を阻害することなく、上下の分離も容易な咬合器の関節構造とする。Embodiments of the present invention will be described below.
(B) A magnetic metal plate is attached to the condylar part of the left and right joints of the superior arch.
(B) A condylar path angle guide plate is installed at the central anterior portion of the left and right upper arch joints.
(C) Attach a magnet to the left and right joint head of the lower bow.
(D) A condylar path angle adjusting screw is installed at the front middle part of the lower arch left and right joint head.
The present invention is configured as described above, and the upper and lower sides are connected by the attraction force due to the magnetic force of (a) and (c), and the adjustment of the condylar path angle and the adjustment of (b) The joint structure of the articulator is such that the condylar path can be guided by the condylar path angle guide plate, the occlusion is stabilized at three points, and the free movement of the joint is prevented within the range of the magnetic force, and the vertical separation is easy.
