Abstract

Device for production of a bush (1)(sic) for production of cog replacement parts with a sleeve (2), a support (socket,sic)(3) in the open side of the sleeve, carrier (4) for supporting a pattern (5) of the cog replacement parts, where carrier (4) consists of a combustible and meltable, or chemically soluble, residue-free material.

Description

The The present invention relates to an apparatus for manufacturing of muffles for the production of dental prostheses with a cuff and a in an open side of the sleeve insertable base and on the base put on carriers for supporting a model of a dental prosthesis.

For the production Of dental replacement parts will be first a model of the dental prosthesis part of a combustible or fusible Material, such as wax, made. This model is going on the carrier attached, and the carrier is then placed on the pedestal. After the pedestal with the carrier was inserted into the cuff, the remaining cavity filled within the sleeve with a hardening muffle material. After this Harden of the muffle material are base, carrier and cuff of the Muffle removed. Then the denture model from the muffle burned out or melted out.

With The manufactured muffle can then made the dentures be by placing a corresponding denture material in the in the Muffel formed cavity filled, for example as a tablet is inserted. By the action of pressure and heat becomes the denture material melted and in by the burnout of the denture model pressed cavity formed. After complete curing of the tooth replacement part is the muffle destroyed and the denture part removed.

Devices for producing such muffles are for example from the DE 90 01 740 U1 , of the DE 92 13 321 U1 and DE-PS 539 734 known. Their disclosure is hereby incorporated by reference.

Of the Invention is the object of a device of the initially to improve the type mentioned. In particular, should the quality of the dental prosthesis be improved.

These The object is achieved by a device of the type mentioned, the characterized in that the carriers consist of a burn-out, fusible or otherwise, for example chemically, resolvable Material exist.

at known devices the carrier for the dental prosthesis model after curing the muffle mass pulled out of the muffle, for example, if the carrier firmly connected to the base, by turning and pulling out of the pedestal. It can considerable forces act on the muffle, causing damage to the muffle in the area lead the muffle cavity can. By the device according to the invention This is avoided as the carrier no longer cured Muffel must be pulled out but burned out, melted out or dissolved in any other way can be. A change the shape of the cavity when pulling out of the carrier can be avoided become. The quality of the manufactured dental prosthesis can be improved accordingly.

Prefers is the carrier from a residue-free burning material. This ensures a clean cavity become.

Also preferred is on the base a molding, for example depression or increase, for the carrier intended. The positioning of the carrier is thereby simplified.

Claims (3)
