It is intended to provide an occludator whereby joint movements at occlusion being similar to the actual tempromandibular joint movements of an individual patient or ideal movements can be reproduced, and a face bow to be used for the occludator. To achieve this object, an occlusion plane against a standard plane is accurately drawn by using the above face bow F whereby the occlusion plane can be drawn at a high accuracy. A solid model of the tempromandibular joint similar to the tempromandibular joint form of an actual patient is used as the joint unit of the occludator K, while the positional relationship in the body at occlusion is three-dimensionally reproduced in the occludator I with the use of the above-described face bow F. It is also intended to provide an occlusion-confirming system and a tempromandibular joint-reproducing system with the use of an occludator whereby joint movements at occlusion being similar to the actual tempromandibular joint movements of an individual patient or ideal movements can be reproduced. To achieve this object, the tempromandibular joint of the body is photographed with a local X-ray CT device to give three-dimensional image data and then a solid model of the tempromandibular joint is constructed based on the three-dimensional image data. This solid model is employed as the joint unit of the occludator K and the positional relationship in the body at occlusion is three-dimensionally reproduced.

The present invention relates to an articulator for the purpose of checking the alignment of dentures, by coupling together models of the upper and a lower jaws, in order to provide a simple movement of the upper and lower jaws, minimize occlusal errors, and accurately mount the upper and lower jaws onto the occlusion surface. Conventional articulators imitate the form of upper and lower jaw movements, wherein a reference axis is established and folded in accordance with a condyle, however, the process completely eliminates muscle movement, and inevitably leads to occlusal errors during upper and lower jaw movement. Consequently, the problem with conventional articulators is the need for post-processing, regardless of the extent of reduction of the occlusal errors through the use of diverse assisting means. In addition, while accurate occlusion cannot be achieved, conventional articulators have a structure that is too complicated and difficult to operate. Therefore, in the present invention, a reference axis is formed on a line extending from the central plane of an upper jaw mounting plate and a lower jaw mounting plate, so that the tangent of rotation creates a vertical motion on the occlusion surface, which allows upward and downward movements that are closer to physiological movements than conventional assisting means, which require making fine adjustments to occlusion, minimizes the margin of error of the articulator, and provides a simple operating structure for the upper and the lower jaw mounting plates and an easier usage thereof.
