Description

[0014] The invention is explained in more detail below with reference to the illustrative embodiments depicted in the attached figures.

[0015] FIG. 1 shows a schematic cross section of a first molar with a splint according to the invention.

[0016] FIG. 2 shows a schematic cross section of an occlusal contact form of two masticatory teeth, with a splint according to the invention on the maxilla and mandible.

[0017] FIG. 3 shows a schematic side view of an occlusal contact form.

[0018] FIG. 4 shows the tooth chart of the permanent dentition numbered according to the old German system.

[0019] As FIG. 1 to FIG. 3 show, the invention relates to a medical device for combating overweight or obesity in humans by achieving a more rapid feeling of satiety. For this purpose, the device is designed as a splint 12 which can be connected to the human maxilla 10 and/or mandible 11 and which equips at least some of the masticatory teeth 13 with an occlusal elevation 14 for reducing the size of the masticatory surface. The splint 12 is an occlusal overlay (anchor) splint adapted to tooth crowns of the masticatory teeth 13, the tooth crown being the upper part of a tooth protruding from the gums.

[0020] The masticatory teeth 13 named after their function are the premolars and molars, in each case to the right and to the left in the maxilla and mandible, which are also covered by the expression buccal teeth. According to FIG. 4, showing the old German system, the number 4 designates in each case the first premolar, the number 5 designates in each case the second premolar, and the numbers 6, 7 and 8 designate the first, second and third molars of the maxilla and mandible.

[0021] The masticatory teeth 13 have a masticatory relief for which the term masticatory surface 15 has become established, although it is not a surface but instead a system of cusps, crests, ridges and furrows. The function of the masticatory teeth is to insalivate and make smaller the morsels of food taken in with the front teeth. Through the contact of the upper and lower masticatory teeth 13 (buccal teeth) with each other, they fit harmoniously in each other in the natural occlusion and form the mastication centre.

[0022] This mastication centre is reduced in size by the splint 12, since the masticatory surface 15 receives an occlusal elevation 14 along at least some of the masticatory teeth 13. This elevation 14 can be designed such that the furrows 16 are filled at least partially or completely, as a result of which an almost plane masticatory surface is made available as a horizontal plane 18 by the occlusal elevation 14, as is shown in FIG. 1 and FIG. 3. The masticatory surface 15 is in this way already reduced. Moreover, the cusp tips 17 of a masticatory tooth 13 can be built over by the occlusal elevation 14, as is likewise shown in FIG. 1. A bite elevation 20 is hereby associated with a spanning of the masticatory relief.

[0023] The occlusal elevation 14 designes the bite elevation 20 preferably by a bar section 23 that is designed as a protruding section of splint 12. The width of the bar section 23 is preferably less than the width of the masticatory surface 15 over the cusp tips 17. Especially preferably the bar section 23 has a width which sbstantially covers each furrow 16 of a masticatory tooth 13 preferably centered. Via the setting of the width of the bar section 23 between the cusp tips 17 of a masticatory tooth 13 the height of the reduction of the masticatory surface can be chosen for each patient. The above description is valid for both a maxilla and a mandible as shown in FIG. 2.

[0024] The occlusal elevation 14 sets, for example, a bite elevation in the range of 0.5 to 2 mm per jaw 10, 11. By being able to choose the height and width of the occlusal elevation 14, it is possible to reduce the masticatory surface 15 by 10 to 50%, for example.

[0025] The splint 12 particularly preferably sets an occlusal elevation 14 in the area of the first and second premolars (4 and 5 according to FIG. 4) and of the first molar (6 according to FIG. 4) of the maxilla and/or mandible 10, 11. According to FIG. 4, an occlusal elevation 14 also extends over the second molar (7 according to FIG. 4).

[0026] The splint 12 can be made of plastic, metal or a ceramic material, wherein these materials can be the colour of teeth.

[0027] These materials can be thermoformed, cast or milled for use. Also mixed, i.e. metal masticatory surfaces can be formed on a plastic splint. The thickness and nature of the splint 12 are adjustable. The thickness of the splint 12 is in the range of 0.3 to 0.5 mm preferably outside the elevation 14.

[0028] The occlusal elevation 14 can also be lined with a soft elastic material 19 (cf. FIG. 1). The soft elastic material is in particular silicone.

[0029] The splint 12 can preferably be fitted so as to be removable by the patient, such that the splint 12 may be worn only temporarily, in particular limited to the period of food intake. It is thus possible to dispel concerns of any kind regarding jaw changes or joint pain. The splint 12 can be supported by friction, by clasps or as model casting.

[0030] The occlusal elevation 14 can be provided with a kind of drainage system or channel 22 for saliva to flow off. As FIG. 1 shows, the elevation 14 is for this purpose bent off laterally for example, with an angle 21.

[0031] Finally, pressure-sensitive components can be built into the elevation 14 for diagnostic or therapeutic purposes in the area of the occlusion field. Moreover, the splint can be equipped with a transponder, in particular a passive transponder, which permits the identification of the splint.
