Abstract

A jaw model for demonstration purposes has interchangeable spare parts (4). The base (1) of the jaw model is provided with compartments (11) for storing the spare parts (4).

Claims

1. A jaw model parts insert parts for demonstration of different dental works and clinical presentations of teeth and partial dentures;

said jaw model comprising a plurality of exchangeable insert parts a jaw arch arranged on a base, said jaw arch having at least one recess for receiving at least one of said exchangeable insert parts (4) representing one of said dental works or presentations, characterized in that an underside of said base (1), defines a plurality of storage compartments (11), said storage compartments (11) providing storage for further of said exchangeable insert parts (4) when said further exchangeable insert parts are not received in said recess of said jaw arch.

2. The jaw model as claimed in claim 1, characterized in that bottom surfaces (12) of said further exchangeable insert parts (4) received in said storage compartments (11) are flush with a bottom surface (13) of the base (1).

3. The jaw model as claimed in claim 2, characterized in that locking elements (5) are provided for releasably mounting each of said exchangeable insert parts (4) in said recess and in said storage compartments (11).

4. The jaw model as claimed in claim 3, characterized in that each of said exchangeable inserts parts (4) are provided with said locking elements (5) at opposite ends of each of said exchangeable insert parts (4).

5. The jaw model as claimed in claim 3, characterized in that each of said locking elements (5) is formed by a ball and a spring (6) exerting a resilient force on said ball for forcing said ball into a locking depression (7) defined in said recess (3) or in one of said plurality of storage compartments (11).

6. The jaw model as claimed in claim 3, characterized in that said locking elements (5) are formed by rubber buffers (9).

7. The jaw model as claimed in claim 2, characterized in that the bottom surface (13) of the base (1) is provided with grip depressions (14, 15) for facilitating gripping of said further exchangeable insert parts (4) in said storage compartments (11).

8. The jaw model as claimed in claim 1, characterized in that a bottom surface (13) of the base (1) is provided with grip depressions (14, 15) for facilitating gripping of said further exchangeable insert parts (4) in said storage compartments (11).

9. The jaw model as claimed in claim 1, characterized in that locking elements (5) are provided for releasably mounting each of said exchangeable insert parts (4) in said recess and in said storage compartments (11).

10. The jaw model as claimed in claim 8, characterized in that each of said exchangeable inserts parts (4) are provided with said locking elements (5) at opposite ends of each of said exchangeable insert parts (4).

11. The jaw model as claimed in claim 9, characterized in that each of said locking elements (5) is formed by a ball and a spring (6) exerting a resilient force on said ball for forcing said ball into a locking depression (7) defined in said recess (3) or in one of said plurality of storage compartments (11).

12. The jaw model as claimed in claim 9, characterized in that said locking elements (5) are formed by rubber buffers (9).

13. The jaw model as claimed in claim 9, characterized in a bottom surface (13) of the base (1) is provided with grip depressions (14, 15) for facilitating gripping of said further exchangeable insert parts (4) in said storage compartments (11).

14. The jaw model as claimed in claim 13, characterized in that each of said exchangeable inserts parts (4) are provided with said locking elements (5) at opposite ends of each of said exchangeable insert parts (4).

15. The jaw model as claimed in claim 13, characterized in that each of said locking elements (5) is formed by a ball and a spring (6) exerting a resilient force on said ball for forcing said ball into a locking depression (7) defined in said recess (3) or in one of said plurality of storage compartments (11).

16. The jaw model as claimed in claim 13, characterized in that said locking elements (5) are formed by rubber buffers (9).

17. The jaw model as claimed in claim 9, characterized in that each of said exchangeable insert parts (4) defines a groove (17), and said recess (3) in said jaw arch defines a guide bead (18), said groove (17) and said guide bead (18) cooperating with each other for adjusting the position of said exchangeable insert part in said recess.

18. The jaw model as claimed in claim 2, characterized in that each of said exchangeable insert parts (4) defines a groove (17), and said recess (3) in said jaw arch defines a guide bead (18), said groove (17) and said guide bead (18) cooperating with each other for adjusting the position of said exchangeable insert part in said recess.

19. The jaw model as claimed in claim 18, characterized in that each of said exchangeable insert parts (4) defines a groove (17), and said recess (3) in said jaw arch defines a guide bead (18), said groove (17) and said guide bead (18) cooperating with each other for adjusting the position of said exchangeable insert part in said recess.

20. The jaw model as claimed in claim 1, characterized in that each of said exchangeable insert parts (4) defines a groove (17), and said recess (3) in said jaw arch defines a guide bead (18), said groove (17) and said guide bead (18) cooperating with each other for adjusting the position of said exchangeable insert part in said recess.
