DEVICE FOR FABRICATING A DENTAL BRACE

Abstract

A device for producing a dental brace, the device including a tooth model; a brace foil; and a separation foil, wherein the separation foil and the brace foil are jointly deep drawn over the tooth model, wherein the separation foil is arranged between the tooth model and the brace foil and separates the tooth model them from the brace foil, wherein the separation foil includes a free standing gripping portion distal from and not in contact with the tooth model, and wherein the free standing gripping portion is grippable by hand.

Claims

1. A device for producing a dental brace, the device comprising: a tooth model; a brace foil; and a separation foil, wherein the separation foil and the brace foil are jointly deep drawn over the tooth model, wherein the separation foil is arranged between the tooth model and the brace foil and separates the tooth model them from the brace foil, wherein the separation foil includes a free standing gripping portion distal from and not in contact with the tooth model, and wherein the free standing gripping portion is grippable by hand.

2. The device according to claim 1, wherein the free standing gripping portion of the separation foil is arranged at distal ends of a jaw of the tooth model (2).

3. The device according to claim 1, wherein the separation foil has a tensile strength between 40 MPa and 75 MPa or between 42 MP and 70 MPa.

4. The device according to claim 1, wherein a side of the separation foil that is oriented towards the brace foil has a greater roughness than a side of the separation foil that is oriented away from the brace foil.

5. The device according to claim 1, wherein the separation foil and the brace foil are simultaneously deep drawn over the tooth model.

6. The device according to claim 1, wherein the separation foil is connected with the brace foil in a disengageable manner before the deep drawing.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The invention is subsequently described in more detail based on an embodiment with reference to drawing figures, wherein:

[0019] FIG. 1 illustrates an exploded view of a device according to the invention;

[0020] FIG. 2 illustrates a bottom view of the device according to the invention according to FIG. 1; and

[0021] FIG. 3 illustrates a side view of the device according to the invention according to FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The embodiment illustrated in FIG. 1 in an exploded view includes a device 1 according to the invention with a tooth model 2, a separation foil 3 and a brace foil 4. The separation foil 3 is arranged between the brace foil 4 and the tooth model 2 and thus prevents that the brace foil 4 penetrates into interdental spaces 5 of the tooth model 2 when the brace foil is deep drawn over the tooth model 2. Simultaneously the separation foil 3 facilitates a separation of the brace foil 4 due to a side 6 of the separation foil that is oriented towards the brace foil 4.

[0023] In order to produce a dental brace that is not illustrated the brace foil 4 and the separation foil 3 are deep drawn over the tooth model 2. The deep drawing of the brace foil 4 and of the separation foil 3 can be performed sequentially as well as simultaneously. A side 6 of the separation foil 3 that is oriented towards the brace foil 4 has a higher roughness than a side 7 of the separation foil 3 that is oriented away from the brace foil 4, so that the brace foil 4 and the separation foil 3 do not enter into a non disengageable connection during deep drawing.

[0024] FIG. 2 illustrates the tooth model 2 with a separation foil 3 that is deep drawn over the tooth model 2 and with a brace foil 4 in a bottom view. A curing of the brace foil 4 has already occurred in the illustrated condition. The brace foil 4 and the separation foil 3 overlap the tooth model 2 so that a protruding portion 8 of the brace foil 4 as well as a protruding portion 9 of the separation foil 3 are provided. The portion 9 of the separation foil 3 that protrudes from the distal ends 10, 11 of the tooth model 2 forms a free standing gripping portion 12 according to the invention.

[0025] FIG. 3 illustrates the retrieval of the tooth model 2 from the brace foil 4. Thus, it is provided that the brace foil 4 is held by a hand 13 at any point of the protruding portion 8 of the brace foil 4. Another hand 14 grips the gripping portion 12 of the separation foil 3 and pulls it out of the brace foil 4 together with the tooth model 2. In order for the separation foil 3 not to tear while pulling the tooth model 2 out of the brace foil 4 the separation foil 3 has a tensile strength of 50 MPa.

[0026] Subsequently a non-illustrated dental brace is fabricated from the brace foil 4, in particular cut out.
