PARTIALLY CONNECTED COMPLETIVE ARTIFICIAL TOOTH HAVING ADJUSTMENT OF dental arch and occlusion bend

Abstract

Provided is a partially connected complete artificial tooth which can efficiently produce a denture in a short time, said denture being harmonious with various patients' chewing movements, oral peripheral tissues, and appearance, and having an attractive appearance and a high-quality occlusal relationship. The partially connected type complete artificial tooth of the present disclosure is connected and fixed in advance in an appropriate occlusal relationship, and appropriately specifies a site that can be standardized and a site that should be separated. In the regions where artificial teeth are brought into contact with each other, the combination of regions constituting the adjacent surfaces of the contact regions, and the angle and area of the contact regions with respect to the virtual occlusal plane of the denture are appropriately defined.

Description

technical field [0001] The present invention relates to techniques for manufacturing prefabricated artificial teeth used in bed dentures, and particularly relates to techniques using CAD (Computer Aided Design) / CAM (Computer Aided Manufacturing) The technology of making dentures. Background technique [0002] In the field of prosthodontics, which supplements the shape and function of lost teeth, artificial teeth are mainly used as a main member for restoring the occlusal function when making bed dentures. In the production of bed dentures by the conventional method, artificial teeth are implanted in bases made of wax or bases made of a combination of wax and resin, and then the wax is replaced with resin such as acrylic. [0003] On the other hand, as shown in Non-Patent Document 1, the number of remaining teeth has been increased based on the results of the 8020 campaign promoted by the Ministry of Health, Labor and Welfare and the Japan Dental Association since 1989 for t...

AI Technical Summary

Problems solved by technology

However, as a result of comprehensiveness, there are the complexity of operations such as artificial tooth arrangement in the design stage (CAD) on a computer, the number of works, and the need for dentures that are processed as a post-processing of dentures as described above. Compared with the advantages of the automated manufacturing process (CAM), there are more disadvantages caused by the manual manufacturing process than the burden of correcting the error of the occlusal relationship that occurs during the bonding operation of the base and the artificial tooth.

Therefore, the realization of labor saving in the denture manufacturing process originally expected from CAD / CAM technology has not been realized in reality.
