Abstract
A muffle furnace for producing dental prosthesis has a muffle into which dental material is placed and a drive to which a piston is connected. The piston is moveable by the drive into the muffle to apply pressure onto the dental material. A pressure sensing device for measuring pressure applied to the dental material is provided. The pressure sensing device has a pressure sensor and a deformation member having a first side and a second side. The first side of the deformation member is subjected to a counter force of the piston and the second side of the deformation member is fixedly attached to the muffle furnace.
