Press muffle

摘要

The invention concerns a press muffle made of an embedding mass for the production of dental restoration parts, with the embedding mass comprising at least one weakly heat-conducting, in particular ceramic, basic powder, with up to 70%, in particular 2% to 40% of the entire embedding mass (12) consisting of an additive having a higher thermal conductivity than the basic powder.

主权项

1. Press muffle fabricated of an embedding mass for the production of dental restoration parts, the embedding mass comprising at least one weakly heat-conducting ceramic basic powder, wherein up to 70% of the entire embedding mass comprises an additive having a higher thermal conductivity than the basic powder, wherein the additive is distributed around the dental restoration part and adjacent to it, wherein the additive is provided according to a type of a cloud in a distribution of concentrations within the embedding mass (12) wherein it is disposed at around the circumference of the press muffle (10), in approximately equal thickness and is further disposed in a lower section of the press muffle adjacent to a shaping space for dental restoration parts, and is disposed at increased height from the lower section forming at least one peak, wherein the maximum concentration is within half a radius (30), as viewed from the shaping space.
