Abstract

An ordering and manufacturing system is used to produce all or part of a tooth replacement from gold. Functions are included for scanning or reading of the treatment situation. Computerized simulating and/or shape-determining functions determine the optimum or desired shape of the tooth replacement. The system is activated for ordering and manufacturing all or part of the tooth replacement. A module system is capable of selecting, from among various manufacturing materials and tools, a manufacturing material in the form of gold and a tool in the form of a casting tool. The module system controls or determines the supply or amount of gold to the casting tool. A dental crown or unit can be made of cast gold. A known ordering and manufacturing system can be used and retain its effective and rapid functions at the same time as another alternative for tooth replacement is presented on the market.

Claims

1. An automated ordering and manufacturing system for producing a tooth replacement part from gold, comprising:

a measurement device configured to determine a shape of a treatment site;

a simulation device configured to generate a desired shape of the tooth replacement part based, at least in part, upon measurements received from the measurement device;

a communications link configured to receive information to initiate ordering and manufacturing of the tooth replacement part, and

a module system configured to, on the basis of a activation signal transmitted by the communications link, of selecting, from a plurality of manufacturing materials and tools, said plurality of manufacturing materials and tools, including at least a manufacturing material in the form of gold or gold material and a tool in the form of a casting tool and, the module system being further configured, on the basis of information supplied to the ordering and manufacturing system through the communications link, to determine an amount of gold material to be supplied to the casting tool.

2. The system as claim 1, wherein in the module system is configured to receive and use information on tooth type to complete a production procedure for the tooth replacement part.

3. The system as claim 2, wherein in the module system is configured to receive and use information on the patient'"'"'s age to complete a production procedure for the tooth replacement part.

4. The system as in claim 1, wherein the module system is configured to receive and transmit information concerning a position of the gold material in the tooth replacement unit.

5. The system as in claim 1, wherein the ordering and manufacturing system is configured to receive or send information regarding the tooth replacement part to a gold supplier.

6. The system as in claim 1, wherein the measurement device is configured to operate within a mobile unit and the system is configured to transfer information from the measurement device to a remote dental technician unit, which is configured to receive several orders.

7. The system as in claim 6, further comprising a broadband connection between the mobile unit and the remote dental technician unit.

8. The system as in claim 1, wherein the measurement device comprise a terminal, which includes means for sending questions and receiving responses to/from the ordering and manufacturing system.

9. The system as in claim 1, wherein the casting tool comprises at least two casting tool parts configured to be able to assume an assembled position to define a mold cavity that is designed for the tooth replacement part.

10. The system as in claim 1, wherein the scanning the measurement device comprises a digital camera.

11. The system as in claim 1, wherein the module system comprises a plurality of modules which are linked by a bus connection and can communicate with the measurement device and each other.

12. The system of claim 1, wherein the system is the PROCERA®

type

13. The system of claim 1, wherein the tooth replace part comprises a dental crown.

14. A tooth replacement part that is made at least partially of a gold material.

15. The tooth replacement part as in claim 14, wherein the part is made completely of gold material.

16. The tooth replacement part as in claim 14, wherein the gold material is cast gold.

17. The tooth replacement part as in claim 14, wherein the gold material is cast gold alloy.
