Abstract

A computer-based method and system of virtually planning a dental restoration in a patient are disclosed, including steps, units or code segments for virtually planning a first dental restoration. First production data is based on the planned first dental restoration for production thereof or of a product related to a medical procedure for installing at least a portion of the first dental restoration in an oral cavity of the patient. Scan data is provided including factual position data and/or factual shape data based on the first dental restoration when at least partly installed in the oral cavity of the patient. The second dental restoration is virtually planned, including adjusting the planned first dental restoration in dependence of the scan data. Second production data is provided based on the planned second dental restoration useful for production of the second dental restoration.

Claims

1. A method of planning a dental restoration for a patient, said method comprising:

virtually planning, via a computer, a first dental restoration for said patient;

providing first production data based on said planned first dental restoration useful for production of said first dental restoration and/or at least one product related to a medical procedure for installing at least a portion of said first dental restoration in an oral cavity of said patient;

providing scan data comprising factual position data and/or factual shape data based on at least a portion of said first dental restoration after modification thereof;

virtually planning, via a computer, a second dental restoration for said patient, comprising adjusting said planned first dental restoration in dependence on said scan data; and

providing second production data based on said planned second dental restoration useful for production of said second dental restoration.

2. The method of claim 1, wherein virtually planning said first dental restoration comprises virtually planning at least one of

an implant supported first dental prosthesis;

a soft-tissue supported prosthesis;

a temporary prosthesis;

a try-in prosthesis;

or

a position of at least one dental implant wherein said first production data comprises data for a surgical template for installing said at least one dental implant in said patient.

3. The method of claim 2, wherein said scan data comprises at least one of

implant position data for an actual position and orientation of said at least one dental implant as said factual position data, or

shape data of an exterior surface of said modified first dental restoration as said factual shape data.

4. The method of claim 2, wherein said first production data comprises data for a try-in prosthesis devised to be positioned in an oral cavity of the patient, such as in relation to said at least one dental implant.

5. The method of claim 1, wherein said at least one product related to said medical procedure is at least one of

a surgical template for drill guided dental surgery, or a try-in restoration.

6. The method of claim 1, wherein said adjusting said planned first dental restoration comprises adapting said planned first dental restoration in dependence of said factual position data.

7. The method of claim 1, wherein adjusting said planned first dental restoration comprises adjusting a bridge framework and/or adjusting at least one virtual tooth of said planned first dental restoration.

8. The method of claim 2, wherein adjusting said planned first dental restoration comprises adjusting a bridge framework in relation to a connection interface of said dental implant.

9. The method of claim 1, wherein an interior surface of said first dental restoration corresponds to an interior surface of said second dental restoration.

12. A method of production of a dental restoration having a desired fit or a product related to a medical procedure for installing said dental restoration in a patient, comprising receiving production data from said computer-based method of virtually planning of claim 1, and further comprising

a) producing said first dental restoration or said product related to a medical procedure for installing at least a portion of said first dental restoration based on said first production data;

and/or

b) producing said second dental restoration based on said second production data.

16. The method of claim 6, wherein adapting said planned first dental restoration in dependence of said factual position data comprises adapting a position for a connection interface in said second dental restoration based on said factual position data and/or adjusting an exterior surface of said first dental restoration by adapting to a shape defined by said factual shape data.

17. The method of claim 9, wherein the interior surface of said first dental restoration comprises a digitized soft tissue surface.

10. A first dental restoration, wherein said first dental restoration is a try-in restoration for controlling a desired fit of a desired dental restoration in an oral cavity of a patient, wherein said try-in restoration is modifiable to provide said desired fit, and comprises

at least one recess for an impression material for receiving a coronal portion of a dental implant for providing scan data of a factual position and orientation of said dental implant, wherein said scan data is useable in virtually planning a second dental restoration having said desired fit.

11. The dental restoration of claim 10, wherein said recess is adapted to receive a cap mounted to a coronal end of said dental implant when implanted, wherein said recess is configured to accommodate said impression material for registering said position and orientation of said dental implant as well as said cap, wherein said dental restoration is positionable on a jaw of said patient when said implant is implanted therein and said cap mounted thereon.

13. A computer-based system for virtually planning a dental restoration for a patient, said system comprising a processing unit adapted to

virtually plan a first dental restoration for said patient;

provide first production data based on said planned first dental restoration useful for production of said first dental restoration and/or at least one product related to a medical procedure for installing at least a portion of said first dental restoration in an oral cavity of said patient;

provide scan data comprising factual position data and/or factual shape data based on said first dental restoration when at least partly installed in said oral cavity of said patient;

virtually plan a second dental restoration for said patient, comprising adjusting said planned first dental restoration in dependence of said scan data; and

provide second production data based on said planned second dental restoration useful for production of said second dental restoration.

14. A non-transitory computer readable medium containing a plurality of code segments for virtually planning a dental restoration in a patient, wherein execution of the plurality of code segments by a computer carries out a method, comprising:

virtually planning a first dental restoration for said patient;

providing first production data based on said planned first dental restoration useful for production of said first dental restoration and/or at least one product related to a medical procedure for installing at least a portion of said first dental restoration in an oral cavity of said patient;

providing scan data comprising factual position data and/or factual shape data based on said first dental restoration when at least partly installed in said oral cavity of said patient;

virtually planning a second dental restoration for said patient, comprising adjusting said planned first dental restoration in dependence of said scan data; and

providing second production data based on said planned second dental restoration useful for production of said second dental restoration.
