Disclosed is an apparatus for manufacturing a tooth model aids. The apparatus for manufacturing a tooth model, which is configured to dewax when molding a tooth model so as to manufacture a dental denture, may include an outer housing, an inner container installed in an inside of the outer housing, a flask unit installed in an inner space part of the inner container. The flask unit includes a mounting plate on which a flask is configured to be mounted, and a cover, the mounting plate of the flask unit includes a wax collection hole on a bottom of the mounting plate, and the cover includes a nozzle which is configured to selectively inject hot water or steam to the flask, the nozzle being formed at a location corresponding to a location of the flask.

A heating device into which a compule of dental material can be inserted to elevate the temperature of the dental material to above ambient temperature prior to clinical use having a base for housing a heating element, a temperature control mechanism for controlling the temperature of the heating element, a power connection for electrically connecting the temperature control mechanism to a source of power and a heating receptacle removably mounted on the base. The heating receptacle comprises a heating tray composed of a conductive material and an upstanding section extending from the heating tray and having a heating chamber open to the atmosphere which is adapted to receive one end of a conventional dispenser in which the compule of dental material is stored for raising the temperature of said dental material in said compule to an elevated temperature.

A method and apparatus for providing clearances in the edges of a denture to accommodate the adjacent anatomical landmarks utilizes a molding compound dispenser in which a sufficient quantity of molding compound to cover the edges of an impression tray is maintained in a limited temperature range above melting temperature. The dispenser may be provided with heat exchange surfaces that can be selectively covered by the practitioner's hand to control the amount of heat loss to the surroundings. Manual pressure may be used to deposit the compound onto the edges.

An electrically-heated wax spatula apparatus is used in molding and preparing wax models for investment casting. The temperature of its spatula portion can be adjusted immediately during use. The wax spatula apparatus comprises a spatula body provided with a heating portion accommodating an electric heating element and a temperature sensor at the front end of the grip portion thereof and a wax-molding spatula portion installed in the heating portion, and a temperature controller for controlling the temperature of the spatula portion depending on a temperature signal from said temperature sensor. The temperature controller comprises a temperature-setting mechanism for independently setting the temperature of the spatula portion and a preset temperature selection mechanism for selecting the preset temperature levels, and the temperature-setting mechanism is a temperature-setting switch disposed at the front end of the grip portion to be operable with a fingertip.

The present invention provides an improved molten wax device for use in building patterns and forms in jewelry making and other applications. The device includes an insulating handle with a holding portion thereon which is held and manipulated between the thumb and fingers of a user's hand and includes a hollow central tube with an electrical heating element mounted thereon, and a removable dispensing tip at a first end thereof. A second end includes an elongated hollow inlet opening, to which an air hose may be connected so as to operate a slidable piston held within an internal bore to selectively extrude heated wax held within the internal bore through variable dispensing tips to form selected wax patterns.

This invention provides a method for making a customized denture from standardized segments of prefabricated prosthetic teeth which may be joined in an adjustable fashion to suit an individual oral cavity. The prosthetic tooth comprises a denture tooth bonded to its individual gum segment to form a prosthetic tooth. The gum segment forms the gum line and simplifies denture fabrication by practically eliminating the time consuming and difficult task of hand forming the gum line during the setup process. A plurality of prosthetic teeth may be adjustably joined in a lateral and/or occlusal relationship. The prosthetic teeth may be adjustable, interchangeable, and joinable with one another to suit an individual oral cavity. The array of prosthetic teeth is selected that most closely suits an individual oral cavity, then evaluated in the mouth of the patient by the dentist and the patient for the mold and shade. Next, the selected prosthetic teeth are conformed in the mouth or on a model representation of the mouth to form a denture. Finally, the denture is cured and finished.

An electrically heated spatula for working heat softenable materials, such as dental wax, includes an elongated hollow sleeve secured at one end to a handle and having a heat producing diode unit supported at the other end. The diode unit includes a hollow metallic cylinder with an apertured metallic end wall. A forward biased diode has a threaded mounting stud disposed in the end wall aperture and is supported in interior of the cylinder in spaced non-contacting relation thereto. The stud extends outwardly of the other end of the sleeve and removably supports a working tip. Power supply conductors extend through the handle and sleeve and are connected to the anode of the diode within the cylinder and to the cathode of the diode through the cylinder, end wall and mounting stud. The arrangement minimizes undesirable transfer of heat from the diode to the cylinder and sleeve and maximizes transfer of heat through the threaded stud to the tip.
