Abstract

The invention relates to a dentel device for the treatment of a dental restoration part, comprising at least one operating program, a storage of the dental device and at least one detection device for at least one object. The detection device can detect data of the object and this data, in particular together with an operating program associated with the object, can be stored in a storage of the dental device or can be compared to the data of objects which have been stored in advance in the storage of the dental device. The dental device, depending on the comparison result of the data of a detected object with the data of objects which have been stored in advance in the storage of the dental device, starts the associated operating program or shows it for selection.

First claim

The invention claimed is:

1. Dental device for treatment of a dental restoration part by curing, firing or pressing, comprising
at least one operating program for operating a curing light or a sintering or pressing furnace,
a storage comprising a plurality of features and
at least one detection device for at least one dental restoration part,
wherein the detection device ( 18 ) can detect data of the at least one dental restoration part and the detected data, together with an operating program associated with the object, can be stored in the storage of the dental device ( 10 ),
wherein the data detected by the detection device is compared to threshold values comprising at least a first threshold value having a first subset of features and a second threshold value having a second subset of features,
wherein if a comparison result is greater than the first threshold value but less than the second threshold value, then an associated operating program is shown for selection and/or started,
wherein selection of an associated operating program comprises selecting a curing program for curing one or more dental restoration parts, selecting a firing program for firing one or more dental restoration parts or selecting a pressing program for pressing one or more dental restoration parts,
wherein starting of an associated operating program comprises one of starting a firing cycle for one or more dental restoration parts, starting a pressing cycle for one or more dental restoration parts and starting a curing cycle for one or more dental restoration parts, and
wherein if the comparison result is greater than the second threshold value, an associated operating program is started comprising one of starting a firing cycle for one or more dental restoration parts, starting a pressing cycle for one or more dental restoration parts and starting a curing cycle for one or more dental restoration parts.

2. Dental device according to claim 1 , wherein the operating program is formed by an operating program executable in the dental device ( 10 ) or by an operating program group executable in the dental device.

3. Dental device according to claim 1 wherein the detection device ( 18 ) is provided with an image recognition device which is suitable for recognizing an image of the object ( 24 ) detected by the detection device and/or features of the image.

4. Dental device according to claim 1 , wherein the data consists of at least one image and/or at least one parameter of the object ( 24 ).

5. Dental device according to claim 4 , wherein the at least one parameter of the object ( 24 ) is a physical and/or optical feature of the object ( 24 ), comprising outer contour, height, width, surface condition, colors, patterns, and/or primer coat of the object.

6. Dental device according to claim 1 , wherein the detection device ( 18 ) is provided with at least one camera ( 20 ) or at least one image sensor, wherein detection areas ( 22 ) extend into the interior of the dental device ( 10 ) and/or outside the dental device ( 10 ).

7. Dental device according to claim 1 , wherein the detection device ( 18 ) detects the position and/or the rotational position of the object ( 24 ) in space and can be pivoted at the dental device ( 10 ) or relative to the dental device.

8. Dental device according to claim 1 , wherein comparing the data of a detected object ( 24 ) with the data of the stored objects is realized using a comparison device.

9. Dental device according to claim 1 , wherein data of at least two objects ( 24 ) is displayed on a display device ( 14 ), wherein the displayed data is most similar to the data of the detected object ( 24 ) and that the user himself/herself chooses the data which corresponds to the operating program or operating program group.

10. Dental device according to claim 9 , wherein the display device ( 14 ) is suitable for displaying the object ( 24 ) detected by the detection device ( 18 ) reduced or increased in size.

11. Dental device according to claim 1 , where an image recognition device is suitable for identifying an object ( 24 ) with the help of detected features of an image for starting the operating program associated with the object or for showing it for selection.

12. Dental device according to claim 1 , wherein the dental device ( 10 ) is formed by a dental firing furnace or by a dental press furnace or by a light curing device.

13. Dental device according to any of the preceding claim 1 , wherein the data is stored in a database with objects which have been stored in advance, which database is comparable with a central server via the Internet and carries out an automatic comparison when it is connected to the Internet.

14. Dental device according to claim 1 , wherein the executable operating program or the executable operating program group is carried out upon confirmation by the user, by pressing a confirmation key, wherein in particular the key forms an indicator of confirmation.

15. Dental device according to claim 1 , wherein in a plurality of dental devices which are configured as firing furnaces a subsidiary display or a central display is implemented in a control room, wherein the subsidiary or central display is switchable for several firing furnaces.
