    摘要： A dental wax shaping and supplying tool includes an electrically heated, pressurized wax reservoir for heating a mass of wax to the desired temperature. Molten wax is selectively discharged from the reservoir through a flow valve in the bottom thereof into an elongated electrically heated flexible tube having connected to its other end an electrically heated spatula for dispensing and shaping the wax. The spatula includes a metallic tube for transmitting the wax from the flexible tube to the spatula spoon. The metal tube is electrically energized to supply heat to the wax flowing therethrough. The wax discharges onto a spatula spoon having an outer rim of electrical resistance material connected to supply heat and a center bowl of electrical insulation.
