て不具合を調整しなければならない欠点を有している。Traditionally, occlusion used to create artificial objects to be placed in the mouth, such as prosthetics (crowns, pre-fujis, partial dentures, complete dentures, etc.), restorations (inlays, onlays, etc.), and templates. The articulator moves the upper arch up and down, back and forth, and swings left and right at positions corresponding to the condylar heads of the left and right sides of the mandible. Because the rotation axis of the upper arch is at the center of physiological mandibular movement, which does not exist in a position corresponding to the head, only dentures with malocclusion can be made, and the problem can be corrected by attaching the dentures in the patient's mouth. It has its drawbacks.

is attached to a swinging part 4 disposed at the rear of the upper bow 2 so as to be able to swing left and right and back and forth, so that the upper bow 3 can swing up and down about a rotating shaft 14 provided on the swinging part 4. By separating the rotary shaft 14, which is the center of the vertical swing of the upper arch 3, and the forward path plate 16 and the sliding part 19, which are the center of the back-and-forth and left-right swing of the upper arch 3, the condylar head can be adjusted. Compared to conventional articulators, in which the part corresponding to the upper arch forms the center of vertical and horizontal oscillation and back-and-forth movement, the structure is much simpler, and the operation is also much easier. In addition, by not setting the rotation axis 14, which is the center of the vertical swing of the upper arch 3, at a position corresponding to the condylar head, the vertical swing of the upper arch 4 is brought closer to the physiological mandibular opening/closing movement,
Therefore, it is possible to eliminate malocclusion of the upper and lower teeth, and to minimize the amount of work needed to adjust defects in prostheses, restorations, templates, etc. in the patient's mouth after they have been manufactured.
