Abstract
Description
[0001] The state of the art includes various methods for digital dental model production, but these often involve producing – or printing – significantly more than is actually necessary, in a very complex, cumbersome, and environmentally damaging way.
[0002] The purpose of the present invention is to print only what is required for the individual patient situation, but then to have the "components" required for further processing steps already available - in a reusable form.
[0003] According to the invention, this problem is solved by providing a base for the actual model, in which numerous raised parallel guides are provided. These guides incorporate minute undercuts into which the individual segments of the printed model can be detachably "snapped." Various mounting options for fixing the upper and lower jaw models, such as screws, magnets, or adhesive mounting combinations, are also provided.
[0004] The digital gear ring can be printed in such a way that it fits exactly to the various guide and locking elements, whereby it is helpful to leave some "air" in the print above the guide elements so that any contamination does not pose a problem.
[0005] Alternatively, it can simply be printed hollow. Then, after isolating the model base, the hollow gear ring can be filled with polyurethane, and the model base can be placed into the liquid polyurethane. Once it has hardened, during which time the polyurethane bonds with the printing material, the model can be cut into its individual segments and precisely attached to the model base.
[0006] Once the patient work has been implemented, the model basis can usually be reused. Reference number list, sheet 1: Fig. 1 1. Model base - top 2.

Claims
[1] Model base and accessories for digital dental model production characterized by , that 1. The model base has firmly connected, raised guide elements that are at least inclined at 0° and can also be slightly conical towards the model.
2. which can be designed in one or more rows 3. which have at least one fine, recessed transverse groove in which the model can be detachably hooked.
4. the digitally printed gear ring is precisely adapted to the surface of the model base and its guide elements 5. The printed gear ring is printed so hollow that it extends over the raised guide elements, is filled with a liquid model material, e.g. polyurethane, and then the model base is fixed exactly over it so that after hardening the guide elements are precisely transferred.
6. that the hollow printed gear ring is fixed to the model base and can be poured through the model base via existing, closable holes - or individually drilled holes.
7. which have two spherical recesses in the rear side area, into which a suitable retaining element can be glued.
8. which has a central recess for a metal plate 9. It has 3 holes for possible screwing.
10. Suitable retaining elements are available for the holes in the base, which, with attached toothed rings, are each inserted into the receptacles of the lower model base in the two-pronged variant with their ball.
11. The counterparts with the two balls are inserted into the upper model base.
12. Connect both together and then lock them with the crossbar.
13. The balls inserted into the model bases are glued in occlusion (maximum interlocking in the final bite) of the models.
