An odontological device to guide occlusion of an individual. The device contains a U-shaped arch with concaves on the side of both the lower jaw and the upper jaw. The bottom surfaces of the concaves form an isthmus separating the concaves from one another. The isthmus includes blanks for individual teeth and uniform, continuous hollows for at least two teeth. The lower jaw side of the device has a lower wing constricting a tongue at least sideways.

1. An orthodontic device for guiding occlusion of an individual, said device comprising: a generally U-shaped arch made of flexible material and configured for extending to molar areas of a dental arch,an isthmus separating the device into generally U-shaped concaves on both the lower and upper jaw
1. An orthodontic device for guiding occlusion of an individual, said device comprising: a generally U-shaped arch made of flexible material and configured for extending to molar areas of a dental arch,an isthmus separating the device into generally U-shaped concaves on both the lower and upper jaw side of the device, said concaves including outer and inner walls,the concaves being structured and arranged for receiving individual's teeth, whereinwithin the molar areas or a part of the molar areas, the inner wall of the concave on the lower jaw side is configured to extend downwards and curve towards the concave so as to essentially follow the shape of the lower jaw and to form a lower wing, which extends from the isthmus of the concave on the lower jaw side towards the base of the mouth cavity, to a distance from 8 mm up to 16 mm. 2. An orthodontic device according to claim 1, wherein said concaves contain uniform compartments that begin from a second premolar and continue towards molars at least partly to an area where the second permanent molar erupts. 3. An orthodontic device according to claim 2, wherein said compartments are shaped like continuous troughs being open at their molar side ends. 4. An orthodontic device according to claim 1, wherein containing within an area of front teeth recesses whose surface walls are essentially smooth. 5. An orthodontic device according to claim 1, wherein said concaves comprise blanks for canines and first premolars. 6. An orthodontic device according to claim 1, wherein said isthmus separating the concaves is thicker at least in an area of molars than in an area of front teeth. 7. An orthodontic device according to claim 6, wherein said isthmus thickness changes stepwise at points between the premolars. 8. An orthodontic device according to claim 6, wherein said isthmus is essentially even and its thickness in the molar area is essentially constant within the range of 3-13 mm and, respectively, its thickness within the thinner area essentially constant within the range of 1-10 mm. 9. An orthodontic device according to claim 1, wherein the walls of the concaves are formed by the outer walls on the labial side or on the buccal side, respectively, and by the inner walls on the opposite sides of the concaves on the lingual side such that the inner wall on the lower jaw side extends downwards lower than the corresponding outer wall. 10. An orthodontic device according to claim 1, wherein said lower wing has been arranged to reach the immediate proximity of the base of the mouth cavity. 11. An orthodontic device according to claim 1, wherein at the point of the ligament of a tongue, the extent to which said lower wing extends towards the bottom of the mouth cavity has been reduced. 12. An orthodontic device according to claim 1, wherein said lower wing extends at the point of the first molar to a maximum distance of 14 mm from the lower jaw side surface of said isthmus and to a distance of 3 to 6 mm in the area of the ligament of the tongue. 13. An orthodontic device according to claim 1 wherein the outer wall on the upper jaw side has been at least partially continued upwards to extend above a gum line. 14. An orthodontic device according to claim 13, wherein said upper side outer wall extends essentially above the gum line in areas of first and second teeth, in areas of first, second, third and fourth teeth. 15. An orthodontic device according to claim 13 wherein said outer wall on the upper jaw side extends at its highest point to 10 mm distance from of the upper jaw side surface of said isthmus. 16. An orthodontic device according to claim 1, the device comprising compartments starting from second premolars and terminating open at their ends, wherein length of the arch of the isthmus on the upper jaw side between the second and third teeth as measured along the center line of the arch is 32 mm and lengths of said compartments are 22 mm on the upper side and 24 mm on the lower side. 17. An orthodontic device according to claim 1, the device comprising compartments starting from second premolars and terminating open at their ends, wherein length of the arch of the isthmus on the upper jaw side between the second and third teeth as measured along the center of the arch line is approx. 37 mm and length of said compartment is 24 mm on the upper side and 27 mm on the lower side. 18. An orthodontic device according to claim 1, wherein said lower wing extends to its maximum distance from the lower jaw side surface of said isthmus at points of first molars.
