Definitions
- the working model at In-Ceram is usually held at 120 ° C for 6 h and then heated to 1120 ° C over 2 h and held for 2 h g) After cooling, the In-Ceram working model can be easily removed from the cavity of the scaffold due to the plaster shrinkage h) Then the scaffold is infiltrated with glass powder, the scaffold is fired and the reworking carried out as usual, such as sanding the edges , Sandblasting and another firing i) With Degusint, the modeled dentures are preheated in a graphite box for 10 minutes under an open oven chamber at 700 ° C and then for 15 minutes at a temperature of 1090 ° C (Degusint U) or 975 ° C (Degusint G) sintered After the sintering time, the graphite box is immediately and quickly moved into the vacuum box, the cooling time
- REPLACEMENT BLA ⁇ (RULE 26) This task is solved by a process which is characterized by the following process steps a) A film is applied to the stump or the stump of the working model b) The applied film on the working model is provided with slurry or metal powder c) The one removed from the working model with Foil provided with slip or metal powder is burned
- the process shows considerable advantages.
- the duplication and thus the production of a second plaster model are omitted.
- the complex surface grinding, the saying and sticking of the working model on an aluminum oxide rail are also eliminated.
- the heating of a working model for 6 hours is no longer necessary to 120 ° C for the purpose of removing the moisture from the working model. Since the film simply burns in the process according to the invention, no special regulation has to be observed when heating to the sintering temperature.
- the gypsum model according to the prior art requires a heating-up time of approx. 2 h necessary to allow the plaster to shrink so that it can be removed from the framework
- prefabricated deep-drawing trays can be fixed between two dies, the shape of which corresponds to the space between them
- the surface of the film can also be produced by immersing it in hot powder or by applying a wetting agent followed by immersion in powder. In both cases, the material corresponds to the slip or metal powder
