Method and system for dental planning

1. A method for computer-based planning of a dental restorative procedure for a patient having a craniooral space and for computer-based planning of a bridge framework for said dental restorative procedure, said method comprising:

determining a first spatial position of a first boundary surface, in said craniooral space, of a veneering of a dental restoration by identifying at least one anatomically fixed reference point that is anatomically stable in a craniooral data set acquired from said patient and then determining from said at least one anatomically fixed referenced point a position in space of at least one of a virtual tooth or an occlusion line, said first boundary surface to be arranged coronally at said occlusion line of said patient;

determining a second spatial position of a second boundary surface, in said craniooral space remote said first boundary surface, of a dental implant of said dental restoration, wherein a top surface of said dental implant is said second boundary surface; and

determining via a computer a third spatial position of at least a portion of said bridge framework relative to at least one of said first and second spatial positions.

2. The method according to claim 1 , comprising determining at least one of said first and second spatial positions as a final spatial position thereof.

3. The method according to claim 1 , comprising adjusting said third spatial position in dependence of an adjustment of at least one of said first and second spatial positions.

4. The method according to claim 1 , wherein said bridge framework has a first outer surface to be arranged apically at a first connection interface, and a second outer surface to be arranged coronally at a second connection interface.

5. The method according to claim 4 , comprising:

determining said second spatial position as a final spatial position thereof;

establishing said first connection interface as a final first connection interface;

determining said third spatial position relative said final first connection interface; and

establishing said second connection interface as a final second connection interface.

6. The method according to claim 4 , wherein said veneering has a second outer surface to be arranged at said second connection interface, and wherein said dental implant has a first outer surface oriented coronally at said first connection interface.

7. The method according to claim 6 , comprising:

determining a position and an angulation of said dental implant; and

establishing said first connection interface as a final first connection interface.

8. The method according to claim 6 , comprising determining said third spatial position of said second outer surface of said bridge framework relative said first spatial position of said first boundary surface and thereby establishing said second connection interface as a final second connection interface.

9. The method according to claim 1 , comprising:

manually fine tuning a position of said dental implant or said veneering; and

automatically adapting the corresponding connection interfaces of the remaining dental units of the dental restoration.

10. The method according to claim 1 , further comprising:

identifying at least three anatomically fixed reference points that are anatomically stable in a craniooral data set acquired from said patient; and

determining a position in space of at least one tooth having one of said first spatial position and second spatial position from said anatomically fixed reference points.

11. The method according to claim 1 , comprising determining said third spatial position by a morphing technique.

12. The method according to claim 1 , further comprising producing a bridge framework based on data obtained from said determined spatial positions.

13. The method according to claim 1 , further comprising producing a dental veneering based on data obtained from said determined spatial positions.

14. The method according to claim 1 , further comprising:

producing a bridge structure comprising a bridge framework and a veneering based on data obtained from said determined spatial positions; and

attaching said veneering to said bridge framework.

15. The method according to claim 1 , further comprising producing a surgical template comprising at least one drill guide based on data obtained from said determined spatial positions.

16. The method according to claim 1 , comprising automatically adapting a shape of a bridge framework, the shape of a dental veneering, and the position of a dental implant.

17. A system for computer-based planning of a dental restorative procedure of a patient having a craniooral space and for computer-based planning a bridge framework for said dental restorative procedure, said system comprising:

a first unit configured to determine a first spatial position of a first boundary surface, in said craniooral space, of a veneering of a dental restoration, by identifying at least one anatomically fixed reference point that is anatomically stable in a craniooral data set acquired from said patient and then determining from said at least one anatomically fixed referenced point a position in space of at least one of a virtual tooth or an occlusion line, said first boundary surface to be arranged coronally at an occlusion line of said patient;

a second unit configured to determine a second spatial position of a second boundary surface, in said craniooral space remote said first boundary surface, of a dental implant of said dental restoration, wherein a top surface of said dental implant is said second boundary surface; and

a third unit configured to determine a third spatial position of at least a portion of said bridge framework relative to at least one of said first and second spatial positions.

18. A computer readable medium having embodied thereon in a non-transitory manner a computer program for computer-based planning of a dental restorative procedure of a patient having a craniooral space and for computer-based planning a bridge framework for said dental restorative procedure, said computer program comprising:

a first code segment configured to determine a first spatial position of a first boundary surface, in said craniooral space, of a veneering of a dental restoration, by identifying at least one anatomically fixed reference point that is anatomically stable in a craniooral data set acquired from said patient and then determining from said at least one anatomically fixed referenced point a position in space of at least one of a virtual tooth or an occlusion line, said first boundary surface to be arranged coronally at an occlusion line of said patient;
