| 摘要 | PURPOSE: To easily perform correction of molars in the turning direction, in such a manner as the end part of an inside dental arch is set to extend at right angles to the main plane of the inside dental arch and as each end part is inserted into the corresponding tube so as to freely turn. CONSTITUTION: A dental arch gear 12 comprises an inside dental arch 1 and an outside dental arch 5, and further, two connecting members 2 connecting each end part 3 of the inside dental arch 1 and molars 4. Also, each end part 6 of the outside dental arch 5 is formed like a hook, and at each hook-like part a neck band or the like is attached to enable to apply desired force to each molar 4. Each connecting member 2 includes a tube part 7 to be attached to a loop-shaped band part 8 and formed so as to be mounted on the molar 4 through the band part 8. The end part 3 of the inside dental arch 1 is slid and inserted into the tube part 7 to be disposed so as to extend at right angles to the main plane of the inside dental arch 1. At this time, the end part 3 is placed to freely rotate within the tube part 7. Consequently, favorable correction force is applied to the molars 4 by the inside dental arch 1.
