A hybrid orthodontic appliance for non-extraction orthodontic treatment

TLDR: In this paper, a hybrid orthodontic device is presented, which consists of an extending unit disposed in an oral cavity between teeth disposed to be opposed to each other, and including a plurality of extension pieces coupled with each other through a screw type to apply extension power to the side of the teeth.

Abstract: According to the present invention, disclosed is a hybrid orthodontic device. The hybrid orthodontic device can ensure a rapid orthodontic procedure by simultaneously ensuring teeth set enlargement and teeth set centrifugal movement for non-extraction orthodontic treatment. The hybrid orthodontic device is installed between teeth to be extended, and applies extension power to the side of the teeth. The hybrid orthodontic device comprises: an extending unit disposed in an oral cavity between teeth disposed to be opposed to each other, and including a plurality of extension pieces coupled with each other through a screw type to apply extension power to the side of the teeth; a teeth coupling unit inserted in the outer surface of the teeth to which the extension power is to applied, including a plurality of bands coupled with the teeth, and including a plurality of wires, each of which has one end fixed to the extending unit and the other end fixed to one side of each of the bands and disposed in a radial direction; and a towing unit for towing the extending unit to the core of the teeth. The hybrid orthodontic device is installed between teeth disposed to be opposed to each other, and can ensure a space by extending a distance between teeth even without extracting a tooth by applying extension power to the side of the teeth. Also, towing power is generated in a core direction of a teeth set, so the teeth are towed to the core side of the teeth set. Thus, a space is ensured between an anterior tooth and a molar. Accordingly, orthodontic treatment can be effectively performed.
