An oven particularly suitable for dental materials is provided with a firing plate on which a calibration apparatus can be removably located. The calibration apparatus includes a meltable element whose melting is detectable by a detecting device. The calibration apparatus is additionally provided with a control device. The firing plate includes a device for receiving therein the calibration apparatus including a non-electrically conducting support for supporting two electrically conducting contact posts of the calibration apparatus.

Oven, in particular for dental material

A method of controlling an oven for producing tooth replacement components. An electric motor moves a piston that acts upon a moldable restoration material. The restoration material is introduced into a muffle oven having an oven hood that can be removed from the muffle. The compactibility curve is established as a function of the type of dental material utilized. Immediately after conclusion of the mold time, the motor is turned off and the oven hood is removed.

Method of controlling an oven

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.
