A method for producing a guide rail having the steps of: Also disclosed are an apparatus for implementing the method, a method for basally shortening prosthetic teeth, and a method for producing a dental prosthesis with such a method for producing a guide rail. The invention further relates to a guide rail produced with such a method and to a dental prosthesis produced with such a method for producing a dental prosthesis.

Method for producing a guide rail for machining prosthetic teeth

The subject matter of the invention is an autopolymerisable two-component prosthetic base material and a method for its production comprising A) at least one liquid monomer component, and B) at least one powdered component, whereby the prosthetic material comprises in components (A) and/or (B) (i) at least one initiator or one initiator system for autopolymerisation, (ii) core-shell particles modified by an elastic phase, and (iii) at least one urethane (meth)acrylate.

Auto-polymerizable prosthetic material and polymerized, fracture-tough prosthetic material with increased colour stability

A method for producing a dental prosthesis, the method including the following steps: affixing several prefabricated prosthetic teeth in a support; producing a prosthetic base according to a virtual model with a CAM method to create tooth sockets that lie parallel to each other; processing the prosthetic teeth basally and adjacent cervically while held in the support in accordance with the virtual model using a CAM method, so that the roots of the prosthetic teeth produced lie parallel to each other when the prosthetic teeth are inserted into the prosthetic base; and, inserting the processed prosthetic teeth together or in groups into the tooth sockets of the prosthetic base and attaching the processed prosthetic teeth in the tooth sockets. Also provided are a dental prosthesis produced by the method and a device for implementing the method.

Method for producing a dental prosthesis with parallel roots of the prosthetic teeth

The subject matter of the invention is a three-dimensional molded body, in particular a milling blank, made of a polymerizable prosthetic material, which is suitable for milling machining by means of CNC and/or CAD/CAM, having a fracture toughness of greater than or equal to 1.9 Mpa&#xb7;mand a fracture work of greater than or equal to 900 J/m. The milling blank preferably comprises core-shell particles modified by an elastic phase and is optionally based on a content of urethane (meth)acrylate polymerized into the polymer. Moreover, a subject matter of the invention is the use of the milling blanks for the production of at least parts of dental prosthetic parts, such as a prosthesis, artificial teeth, bridges, or of orthodontic appliances and instruments in medical field.
