摘要:
A method and apparatus for the design and manufacture of dentures wherein the number of office visits that a patient must attend in order to develop and obtain dentures is reduced. In one embodiment, during a first visit, final impressions and a measurement of the patient's upper lip is obtained. In one embodiment, a lab then creates a denture base and applies tooth replicas. In one embodiment, this is done using a physical fabrication aid of an embodiment of the present invention. Alternatively, the denture base can be created from a digital representation, and the denture base is then preferably sized and adjusted during the patient's second visit before final dentures are created and provided to the patient during the patient's third visit.

The invention relates to a dental restoration model comprising a positive model (15) of a dental restoration piece. Said positive model (15) defines at least the outer contour (36) of a dental restoration piece to be made using lost wax technology and is provided with a locating pin region which is defined especially according to a given optimization process. The invention is characterized in that the locating pin region is provided with a guiding element (30) which accommodates and/or guides a material feeder (22, 24, 26 and 28).

A system enabling precise control of dental wax application by fine temperature control includes a PID thermostatic controller, at least one cartridge heater and a temperature sensor. The cartridge heaters are embedded in a heater block containing heating that transfers heat to a barrel of a wax applicator when the barrel is intermittently placed into a heating chamber of the block.

The invention relates to a wax dispenser for dental technology comprising: a wax reservoir in the shape of a hollow tube which contains a liquid wax therein; a nozzle which is disposed on the front end of the wax reservoir and which is in fluid communication with the wax reservoir; a heater which heats wax to keep wax contained in the wax reservoir in liquid state; an air-pressure supplier which increases the pressure in the wax reservoir by the introduction of air from the outside in a pressurization mode and decreases the pressure in the wax reservoir by the discharge of air to the outside in a depressurization mode; and a dispenser actuator comprising a wax passage which allows the wax reservoir to be in fluid communication with the nozzle, and a passage open/shut device arranged to open and shut the wax passage to discharge wax contained in the wax reservoir through the nozzle in the pressurization mode and to introduce wax from the outside to the wax reservoir through the nozzle in the depressurization mode. Therefore, it is possible to facilitate user's convenience and the work efficiency by charging wax in the wax dispenser in the shape of a pen, by discharging wax according to air pressure and by controlling the discharge of wax precisely.

The invention provides a digital dentistry system that utilizes a haptic interface and features a computer-based design application configured to allow the intuitive construction of irregular, amorphous three-dimensional structures typically seen in dental restorations, utilizing, where appropriate, the design skills of a user. In certain embodiments, the system provides a comprehensive digital solution for dental labs in the business of creating dental restorations such as partial frameworks, crowns, copings, bridge frameworks, implants and the like, with a sense of touch provided by a haptic interface device.
摘要:
Custom dental prosthesis or implants each individually designed and manufactured to replace nonfunctional natural teeth positioned in a jawbone of a specific pre-identified patient are provided. An example dental prosthesis/implant includes a dental implant body having a prosthesis interface formed therein to receive an occlusally-facing dental prosthesis component. The prosthesis interface has a custom three-dimensional surface shape positioned and formed to create a form locking fit with respect to the occlusally-facing dental prosthesis component when positioned thereon.

A wax shaping tool of the present invention is a tool which is used in manufacturing an artificial denture model by a dental technician. The tool comprises a tubular handle portion 10 having a slit 12 extending in an axial direction for interconnecting an internal bore with the external space, a wax cartridge holder 13 provided on upper side of the handle portion including edges of the slit for slidably provided guiding a wax cartridge 16, a roller 14 rotatably onto said handle portion so as to protrude from a peripheral part thereof, a first drive which removably holds a rear end of the wax cartridge and is movable in an axial direction in the wax cartridge holder, a second drive (20, 21, 23, 24; 33, 34, 35, 36) provided in said handle portion for converting a rotating movement of the roller into the rectilinear movement and for transmitting the motion to the first drive, a spatula 26 provided on a front end of the handle portion, a wax melter portion 27 for contacting and melting the wax cartridge portion projected out of a front end the wax cartridge holder, and a heater 28 for heating up said spatula and said wax melter portion. Since the amount of melted wax can be freely controlled according to the rotation of the roller by fingers, said tool can be easily used.

The present invention primarily relates to an apparatus for improving the efficiency of the waxing-up work mainly in the dental technology. The apparatus comprises a casing which can be held in the palm of the operator's hand, a nozzle member connected to the end of the casing, a means for heating and a means for feeding bar-shaped solid wax which is accommodated in the casing. This apparatus allows the operator to ooze out a proper amount of melted wax required for the waxing-up work from the end of the nozzle member and can solve many problems caused by the conventional method using spatulas.
