Abstract

Claims (17)

1. A method of producing a dental object ( 100 ), comprising the step of:

producing a support structure ( 101 ) on the dental object ( 100 ) with a predetermined breaking point ( 103 ) which is arranged such that, after the predetermined breaking point ( 103 ) has been separated, a residual portion ( 105 ) of the support structure ( 101 ) remains on the dental object ( 100 ), and

wherein the dental object ( 100 ) is attached to a further dental object ( 200 ) and the residual portion ( 105 ) of the support structure ( 101 ) is fully or partially inserted into a recess ( 107 ) of the further dental object ( 200 ).

2. The method according to claim 1 ,

wherein the predetermined breaking point ( 103 ) is arranged at a predetermined distance from or on the dental object ( 100 ).

3. The method according to claim 1 ,

wherein the support structure ( 101 ) tapers towards the predetermined breaking point ( 103 ).

4. The method according to claim 1 ,

wherein a predetermined residual amount of the support structure ( 101 ) remains on the dental object ( 100 ) after separation of the predetermined breaking point ( 103 ).

5. The method according to claim 1 ,

wherein the support structure ( 101 ) with the predetermined breaking point ( 103 ) is automatically planned by an algorithm.

6. The method according to claim 1 ,

wherein the dental object ( 100 ) and/or the support structure ( 101 ) are produced by a 3D printing process.

7. The method according to claim 1 ,

wherein the residual portion ( 105 ) generates an adhesive gap ( 109 ) between the dental objects ( 100 , 200 ).

8. The method according to claim 1 ,

wherein the dental object ( 100 ) is a dental arch and the further dental object ( 200 ) is a denture base.
