Definitions

  • the invention relates to a method for the production of dental parts of dental metal powder.
  • toothed parts are understood in particular to be bridge frameworks and copings as well as finished prostheses.
  • Firing support is fixed, or by remaining on a doubled model, or is placed in a muffle filled with investment or temperature-resistant powder.
  • All-ceramic dentures are known which covers about 10% of the dental market.
  • a common method is to mill out a scaffold from an isostatically pre-pressed block of ceramic, in particular zirconium oxide, using the CAD / CAM technique.
  • the dentition of the patient or a working model is scanned and the framework is milled on the basis of the scanned model. With this procedure will be also tooth parts from massive metal blocks milled out.
  • a major disadvantage of this method is, inter alia, that the milling of ceramics is associated with dust and high mechanical
  • Non-ferrous alloys and precious metal alloys applicable.
  • EP 1885 278 B1 (WoIz) describes the preparation of a dental metal slip for the first time. An improved one
  • CrCo-Schlicker is commercially available under the name WOLCERAM CrCo-Schlicker, which is used here. It consists of 98% by weight of CrCo powder and 2% by weight of water (suspension liquid) with minor additions of organic compounds and preservatives. Before this slurry is used, conditioning of the slurry is strongly recommended to prevent agglomerates. A corresponding
  • Silicone rubber filled to make a round disc with a diameter of 95mm and a thickness of 20mm The solidification of the slip into a usable blank (green body) takes place in the mold by drying. To make sure that there are no air bubbles in the slurry, another pressure treatment is carried out at 6 bar, through which air is pressed out of the slurry.
  • the drying process is then carried out by drying the mold in a drying cabinet at 65 ° C. for 7 h.
  • the drying can also be carried out under vacuum and / or under pressure. It is recommended to use the bottom of the mold with a
  • water adsorbing layer e.g., blotting paper
  • the sintered product has the following properties.
  • the chemical composition was determined by emission spectroscopy. Co-% balance Mn-% ⁇ 1, 0 Cr-% 28.0-30.0 Si-% ⁇ 1, 0 Mo-% 5,0-6,0 Fe - C - Ni traces ⁇ 0,5%
  • Difficulties are milled. The material is then stable in an aqueous environment.
