Abstract

Disclosed is a computer-implemented method of designing a number of dental restorations for a patient, wherein the method includes: selecting a composed set of teeth including a number of teeth, where the number of teeth are arranged spatially relative to each other forming a high aesthetic composition; applying the composed set of teeth to a virtual three dimensional representation of the patient's present oral situation to obtain an initial set of teeth; optionally modifying one or more parameters of one or more of the teeth in the initial set of teeth to obtain a finalized set of teeth.

First claim

The invention claimed is:

1. A system for designing a number of dental restorations for a patient, wherein the system comprises a computer configured to:
select a composed set of teeth comprising a number of teeth, where the number of teeth are arranged spatially relative to each other forming an arranged composition;
apply the composed set of teeth to a virtual three dimensional representation of the patient's present oral situation to obtain an initial set of teeth;
collectively modify the entire initial set of teeth to obtain a finalized set of teeth, wherein the collective modification involves modifying the entire set of teeth simultaneously using the computer;
wherein the collective modification involves rotation of the teeth.

2. The system according to claim 1 , wherein the collective modification involves rotation of the teeth relative to a median line of the patient's face.

3. A computer-implemented method of designing a number of dental restorations for a patient, wherein the method comprises:
selecting a composed set of teeth comprising a number of teeth, where the number of teeth are arranged spatially relative to each other forming an arranged composition;
applying the composed set of teeth to a virtual three dimensional representation of the patient's present oral situation to obtain an initial set of teeth;
collectively modifying a plurality of the teeth in the initial set of teeth to obtain a finalized set of teeth, wherein the collective modification involves modifying the plurality of teeth simultaneously using the computer;
wherein the method further comprises modifying the entire initial set of teeth collectively and the collective modification involves rotation of the teeth.

4. The computer-implemented method according to claim 3 , wherein the method further comprises:
modifying one or more parameters of the plurality of teeth in the composed set of teeth before applying the representation of the patient's present oral situation to obtain a modified composed set of teeth.

5. The computer-implemented method according to claim 3 , wherein the collective modification involves rotation of teeth relative to a median line of the patient's face.

6. The computer-implemented method according to claim 3 , wherein the collective modification involves changing a geometric shape of the teeth in a center of the teeth.

7. The computer-implemented method according to claim 6 , wherein the geometric shape of the central teeth is or is a combination selected from:
an oval shape;
a triangular shape; or
a rectangular/square shape.

8. The computer-implemented method according to claim 3 , wherein the method further comprises mirroring of teeth.

9. The computer-implemented method according to claim 3 , wherein the method further comprises cloning of teeth.

10. The computer-implemented method according to claim 3 , wherein the method further comprises providing collision mapping relative to an antagonist.

11. The computer-implemented method according to claim 3 , wherein the method further comprises virtually fitting the finalized set of teeth to a virtual retainer.

12. The computer-implemented method according to claim 11 , wherein the method further comprises cutting the finalized set of teeth to the retainer.

13. The computer-implemented method according to claim 11 , wherein the initial set of teeth may be fitted/cut to the retainer and/or to the gingival before the set of teeth becomes the finalized set of teeth.

14. The computer-implemented method according to claim 11 , wherein the method further comprises virtually designing the retainer.

15. The computer-implemented method according to claim 3 , wherein the method further comprises virtually cutting the finalized set of teeth to the gingival.

16. The computer-implemented method according to claim 3 , wherein the method further comprises fitting the finalized set of teeth to its anatomical correct position in the gingival.

17. The computer-implemented method according to claim 3 , wherein the method further comprises adding virtual guiding lines to be overlaid on the initial set of teeth.

18. The computer-implemented method according to claim 3 , wherein the selecting a composed set of teeth comprising a number of teeth involves selecting the composed set of teeth from an electronic library comprising a number of different composed sets of teeth.

19. The computer-implemented method according to claim 3 , wherein the collective modification involves modifying the entire set of teeth uniformly using the computer.

20. The computer-implemented method according to claim 3 , wherein the collective modification involves modifying the entire set of teeth identically using the computer.

21. A nontransitory computer readable medium storing thereon a computer program, where said computer program is configured for causing computer-assisted designing of a number of dental restorations by performing the method of claim 3 .
