The present invention relates to an orthodontic fixing apparatus. The orthodontic fixing apparatus comprises a linear fixing body, bisymmetrically defined, having a plurality of connection grooves in each left and right sides thereof, and a plurality of cylindrical fixing rings arranged on the upper and lower sides of the central portion of the fixing body with a connection member being placed between the upper and lower sides, wherein a screw is inserted, to thereby fix the fixing body to the palate. Each fixing ring may protrude by a width of 0.1 mm to 4 mm in a direction of contact with the palate to minimize the contact of the fixing ring or the fixing body with the palate. Also, the fixing ring may comprise a taper having a diameter that gradually decreases from an inlet to an outlet along an insertion direction of the screw, wherein an internal thread is arranged in the fixing ring. Thus, since the screw is firmly supported and inserted into the palate, the fixing apparatus may serve as a solid anchorage. Also, since the fixing apparatus is easily placed, the fixing apparatus is convenient to use. In addition, since the fixing apparatus is fixed while minimizing the contact area with the palate, it may prevent the palate from being damaged or becoming inflamed.
