Dental simulation machine

1. A dental simulation machine including a support having an outer facing support surface for engagement by a finger of a user to support a hand of the user, the support surface being moveable between a plurality of positions, wherein a detent is operable to hold the support surface in each of the plurality of positions, wherein the support is pivotally mounted by a pivot to enable the support surface to move between the plurality of positions and wherein the pivot includes a pivot axis and movement of the support surface in a first direction parallel to the pivot axis disengages the detent.

2. A dental simulation machine as defined in claim 1 wherein the plurality of positions includes a first position for engagement by a finger of the user to support the hand of a user in a first position and includes a second position for engagement by a finger of the user to support the hand of the user in a second position.

3. A dental simulation machine as defined in claim 2 wherein the plurality of positions includes a third position for engagement by a finger of the user to support the hand of the user in a third position.

4. A dental simulation machine as defined in claim 1 wherein the plurality of positions includes a stored position.

5. A dental simulation machine as defined in claim 1 wherein the support is pivotally mounted by a pivot to enable the support surface to move between the plurality of positions.

6. A dental simulation machine as defined in claim 1 wherein the support includes a generally elongate body with the support surface being provided at an end of the body.

7. A dental simulation machine as defined in claim 6 wherein the support is pivotally mounted by a pivot to enable the support surface to move between the plurality of positions and wherein the support surface is provided at a first end of the body and the pivot is provided proximate a second end of the body.

8. A dental simulation machine as defined in claim 1 wherein the support includes a generally elongate body with the support surface being provided at an end of the body and wherein the support body is biased in a second direction, opposite to the first direction, parallel to the pivot axis to engage the detent.

9. A dental simulation machine as defined in claim 1 wherein the support is mounted to a rest.

10. A dental simulation machine as defined in claim 9 wherein the support is pivotally mounted by a pivot to enable the support surface to move between the plurality of positions and wherein the support is pivotally mounted by the pivot to the rest.

11. A dental simulation machine as defined in claim 10 wherein the support is located on a first side of a region of the rest and a pivot pin of the pivot is accessible on a second side of the region of the rest to disengage the detent.

12. A dental simulation machine as defined in claim 9 wherein the plurality of positions includes a stored position and wherein the support is received in a recess of the rest when the support surface is in the stored position.

13. A dental simulation machine as defined in claim 9 wherein the rest is generally U-shaped having a first arm and a second arm.

14. A dental simulation machine as defined in claim 13 wherein the support is mounted to the first arm.

15. A dental simulation machine as defined in claim 14 further including a second support having a second support surface for engagement by a finger of a user to support a hand of the user, the second support surface being moveable between a second plurality of positions, wherein the second support is mounted to the second arm.

16. A dental simulation machine as defined in claim 15 wherein the support and/or the second support are mounted on an inside of the U-shape.

17. A dental simulation machine as defined in claim 1 including a viewing screen for viewing a virtual simulated model.

18. A dental simulation machine as defined in claim 17 wherein the virtual simulated model includes a representation of the support surface.
