FIELD: furnaces; dentistry.
SUBSTANCE: invention relates to dental furnace. Furnace consists of sintering chamber for thermal treatment of restored parts of teeth. Sintering chamber is connected to negative pressure source via suction line. Valve mechanism is located between sintering chamber and suction line, and with its help line is closed in direction to sintering chamber to keep negative pressure in it. Suction line between valve mechanism and source of negative pressure is ventilated, in particular via connection with ambient air.
