This invention provides an orthodontic device, which includes a brace, two elastic wires, and two joining bases, wherein the two end parts of the brace are extended toward rear side of the brace, and each end part of the brace is equipped with a collar disposed with a fixing part those two elastic wires are connected with the fixing parts of those collars in a separable manner and the other end of each elastic wires, oppose to the end connected with fixing part, is abutted against the joining base. The abovementioned orthodontic device is installed at the tongue side in the mouth and only needs respectively to fix the collar of the brace on the dental crown and to fix the joining base on the crown of another wisdom tooth that is relatively close to the base of the tongue and grows horizontally, so that the wisdom tooth that grows horizontally can be corrected to the right position progressively by adjusting the elastic wire, and spacing and alignment of teeth can also be corrected, while the installation process is simple and convenient, and the correction time can be shortened.本發明提供一種牙齒矯正裝置,其包括有一托架、兩彈線以及兩結合座,其中該托架的兩端部朝向托架後側延伸,且於托架的各端部設有一環套,並於該等環套設有一固接部;該兩彈線係分別與該等環套的固接部可分離地相連接;以及該等彈線相對於與固接部連接之一端分別係與該等結合座相抵頂。前述牙齒矯正裝置係裝設於口腔內舌側,僅需將托架之環套固定於齒冠上,並將結合座固定於另一相對靠近舌根的水平生長的智齒之齒冠上,即可藉由調整彈線而漸進地扶正該水平生長之智齒,並可矯正牙齒間距及排列,且裝設過程簡單方便,並可縮短矯正時間。1‧‧‧牙齒矯正裝置10‧‧‧托架11‧‧‧端部12‧‧‧環套13‧‧‧固接部131‧‧‧插槽20‧‧‧彈線30‧‧‧結合座31‧‧‧頭部32‧‧‧柱體33‧‧‧底座
