Method for Producing a Dental Prosthesis
20170135790 · 2017-05-18 ·

The invention relates to a process for producing a dental prosthesis with the chronological steps:

A) Inserting the prosthetic teeth into the prosthetic base and connecting them with it in such a way that after their insertion into the prosthetic base the prosthetic teeth have limited movability in the prosthetic base

B) Changing the position and/or the orientation of at least one prosthetic tooth in the prosthetic base;

C) Fixing the prosthetic teeth on the coronal side in a key, and securing the orientation and position of the prosthetic teeth to one another in the changed position and/or orientation;

D) Separating the prosthetic teeth from the prosthetic base;

F) Fastening the prosthetic teeth in the prosthetic base with a cement or an adhesive, the gaps between the surfaces of the prosthetic base that are provided for fixation of the prosthetic teeth and the prosthetic teeth being filled with the cement or the adhesive; and

G) Allowing the cement or adhesive to harden, the prosthetic teeth being solidly connected with the prosthetic base, so that the orientation and position of the prosthetic teeth to one another and to the prosthetic base is fixed, and separating the key from the prosthetic teeth.

The invention also relates to a dental prosthesis produced using such a process and a kit to carry out such a process.

ARTIFICIAL TOOTH

An object is to provide an artificial tooth that can be attached to a denture base designed by CAD/CAM to be formed easily and accurately when the artificial tooth is arranged on the denture base.

In an artificial tooth (21) that has a shape corresponding to a denture base that is designed on CAD based on three-dimensional data and is cut out, a regulator (21a to 21h) that regulates the rotation on the axis of the tooth as the center is provided for a portion to touch the denture base, and the regulator has a shape so as not to engage with the denture base in the direction of the axis of the tooth.
