A dental traction device comprises an extension main-body, a tractive-body, a blocking-stopping-body, and a seat-body. When using, the dental orthotics are firstly set and the dental correction archwire connection is set, and the bone nail is set at the gum； then, the seat-body is fixed on the dental correction archwire； one end of the elastic element is bypass the blocking-stopping-body to stick and engage on the tractive-body and the other end is stuck and engaged on the bone nail； then the blocking-stopping-body is cooperated with the tractive-body to fix the elastic element to avoid falling-off； and the contraction elastic force of the elastic element generates the pulling force to the dental correction archwire and the teeth by using the extension main-body as the force moment to produce the traction correction effect； and so as to achieve the practicality and progressiveness which is convenient in use and avoids falling-off.
