Definitions

  • the manufacture of the matrix from the platinum foil 30 is a very labor-intensive operation.
  • the systems for the production of dental models have been known that have been replaced by sandwiches, which consists of black sand, the electric sound and gypsum have been interfered with in the quality of the binder.
  • the indicated first components and components are taken at 35 proportions 1: 1: 1. From these components, one prepared - 2 - keru, which is poured directly into the tooth with a cleaned tooth, then, together with the water splicer, after drying, it is removed from the tooth when the tooth is removed.
  • the defective area of the tooth model is filled up with a massive mass, after which the model is combined with a massive mass that burns at a temperature of 1000 ° C. After firing, the model is placed in the water, and this model is also depleted and the process is removed due to the “Problems of the Occupational” system.
  • the temperature of the firing unit must be set to 1080.. . 1200 ° C, depending on the composition of the bulk mass.
  • the main task of the invention was to create a system for the production of dental models with fixed removable devices.
  • a model made from the proposed composition contains aluminum titanium, magnesia-alumina spinel and a bonding material.
  • 35 groups of items are subject to use - 5 - call the proposed system for the manufacture of models, such as laying, transport and field devices.

Then, on the base layer, the dentin layer is applied, the latter burns and cools under the same conditions. Then, with the use of diamond tools with a business software, you will receive the required operation and ignition to shut it down. At the end of the firing process, the ready-to-use one manually separates the models.
