  • Patent number: 6794612
    Abstract: A modeling device intended for applying wax to the crown region of a tooth which is to be modeled is designed for the purpose of improving its characteristics in use such as its handling during modeling work, when inserting new wax cartridges etc. as an elongated, writing device-like base body, which includes at one end a modeling tip and inside accommodates a forward feed drive for a wax cartridge and a heating device which is used to render the wax to be processed into a liquid state at the end facing the modeling tip, so that as the forward feed drive is actuated liquid wax can be discharged from the outlet. For the purpose of supplying electric energy a cable is attached to the front side end and in fact to the concave side of the curved modeling tip.

For the purpose of supplying electric energy a cable (2) is attached to the front side end (5) and in fact to the concave side of the curved modeling tip (6). The connection of the cable (2) prevents neither the manner in which the device is guided when moving nor the view of the actual working area.
