Abstract
The invention relates to a method for processing a dental material (), in particular pressing and curing a dental material, by means of—a molding insert () that has a pre-pressing area () which adjoins a molding area (), wherein the pre-pressing area () is designed to receive the dental material (), and—a pressing furnace with a firing chamber () for receiving the molding insert (). The method has the following steps: —introducing the dental material () into the pre-pressing chamber (); —heating the firing chamber (), in which the molding insert () is located, pressing the dental material () towards the molding area () using a pressing punch () by applying a force onto the pressing punch () during a first processing phase, wherein the pressing punch () is moved, and the pressing punch speed is detected as a speed profile dependent on the time; and adjusting the firing chamber (), in particular cooling the firing chamber to a second temperature, during a second processing phase starting at a point in time at which the detected speed profile matches a first speed profile without reducing the force applied to the pressing punch ().
