Abstract

An object of the present invention is to provide a method for manufacturing a dental prosthesis capable of properly arranging a dental reinforcement when a dental prosthesis made of resin where the dental reinforcement is arranged is manufactured. The method includes turning information on an intraoral shape into data: designing, in a form of data, a shape of a resin body that is a part formed of resin based on the data; designing, in the form of data, a position of a dental reinforcement that is to be arranged inside the resin body; and forming, in the form of data, a space and an opening that communicates with an outside in the position in the resin body where the dental reinforcement are to be arranged, based on the position, to design a resin body with an opening.

First claim

The invention claimed is:

1. A method for manufacturing a dental prosthesis where a dental reinforcement is arranged inside a resin and a plurality of false teeth, the method comprising:
turning information on an intraoral shape into data;
designing, in a form of data, a shape of a resin body that is a part formed of resin based on the data;
designing, in the form of data, a position of a dental reinforcement that is formed of fibers and is to be arranged inside the resin body and is extending in the direction of arranging the false teeth;
forming, in the form of data, a space and an opening that communicates with an outside in the position in the resin body where the dental reinforcement is to be arranged extending in the direction of arranging the false teeth, on the opposite surface of the false teeth from an occlusal surface, based on the position, to design a resin body with an opening;
making the resin body with an opening, based on the designing of the resin body with an opening, and arranging the dental reinforcement formed of fibers in the opening of the resin body with an opening; and
covering the opening with resin after arranging the dental reinforcement.

2. The method according to claim 1 , further comprising: calculating strength after said designing a position of a dental reinforcement.

3. The method according to claim 1 , further comprising:
after said forming a space and an opening, to design a resin body with an opening,
making the resin body with an opening;
inserting the dental reinforcement into the resin body with an opening; and
covering the opening of the resin body with an opening.

4. The method according to claim 1 , wherein the dental reinforcement is formed in a board shape.
