<p>The present invention relates to a dental prosthesis, and more particularly, to a screw- engagement type dental prosthesis which enables non-preparation of the natural tooth because it is manufactured by division into three pieces, which can be simply installed, and in which the occlusal pressure can be uniformly dispersed. Also, the present invention relates to a method of casting a screw- engagement type dental prosthesis by using a bolt made of carbon or ceramics. The dental prosthesis of the present invention is characterized by comprising a keeper disposed to wrap an abutment tooth of one side from the lingual side, a base disposed to wrap an abutment tooth of other side and the keeper, and a body acting as an artificial tooth and is engaged with the base and the body by means of a screw, and is disposed to wrap the abutment tooth of one side or the abutment tooth of the other side in a direction opposite to a direction in which the keeper wraps.</p> |
