Abstract

A container ( 100 ) for producing a self-curing or dual-curing dental synthetic material composition ( 200 ), which container includes a deformable wall ( 101 ), having a first synthetic material component ( 103 - 1 ); and a second synthetic material component ( 103 - 2 ) for curing the synthetic material composition ( 200 ) or starting a curing reaction.

First claim

The invention claimed is:

1. A container ( 100 ) for producing a self-curing or dual-curing dental synthetic material composition ( 200 ) comprising
a deformable wall ( 101 ),
a first synthetic material component ( 103 - 1 ); and
a second synthetic material component ( 103 - 2 ) for curing the synthetic material composition ( 200 ) or starting a curing reaction,
wherein the synthetic material composition ( 200 ) comprising the mixed first synthetic material component ( 103 - 1 ) and second synthetic material component ( 103 - 2 ) has a viscosity which is in the range of 50-3000 Pas for flowable synthetic material compositions and between 3000-50000 Pas for stoppable synthetic material compositions.

2. The container ( 100 ) as claimed in claim 1 ,
wherein the container ( 100 ) is in the shape of a tube or bag.

3. The container ( 100 ) as claimed in claim 1 ,
wherein the deformable wall ( 101 ) is formed from silicone.

4. The container ( 100 ) as claimed in claim 1 ,
wherein the deformable wall ( 101 ) is transparent in a wavelength range of 390 nm to 520 nm.

5. The container ( 100 ) as claimed in claim 1 ,
wherein the first synthetic material component ( 103 - 1 ) and/or the second synthetic material component ( 103 - 2 ) are arranged in the form of a string within the container ( 100 ).

6. The container ( 100 ) as claimed in claim 5 ,
wherein the first synthetic material component ( 103 - 1 ) in the form of a string and the second synthetic material component ( 103 - 2 ) in the form of a string are twisted.

7. The container ( 100 ) as claimed in claim 1 ,
wherein the first synthetic material component ( 103 - 1 ) comprises a polymerizable organic matrix having a mixture of monomers, initiator components, stabilisers and pigments.

8. The container ( 100 ) as claimed in claim 1 ,
wherein the first and/or second synthetic material components ( 103 - 1 , 103 - 2 ) are in the form of a powder, paste, liquid or gel.

9. The container ( 100 ) as claimed in claim 1 ,
wherein the container ( 100 ) comprises a spout ( 105 ) for squeezing out the synthetic material composition ( 200 ).

10. A method for producing a self-curing or dual-curing dental synthetic material composition ( 200 ), comprising:
kneading (S 101 ) a container ( 100 ) having a deformable wall ( 101 ) and comprising a first synthetic material component ( 103 - 1 ) and a second synthetic material component ( 103 - 2 ) for curing the synthetic material composition ( 200 ) or starting a curing reaction,
wherein the synthetic material composition ( 200 ) comprising the mixed first synthetic material component ( 103 - 1 ) and second synthetic material component ( 103 - 2 ) has a viscosity which is in the range of 50-3000 Pas for flowable synthetic material compositions and between 3000-50000 Pas for stoppable synthetic material compositions.

11. The method as claimed in claim 10 ,
wherein the container ( 100 ) is heated to a predetermined temperature before or during the step (S 101 ) of kneading.

12. The method as claimed in claim 10 ,
wherein the kneading or mixing of the first and second synthetic material components ( 103 - 1 , 103 - 2 ) is performed at low pressure or under vacuum.
