The invention discloses an independent low frictional force, including bracket base, located in the bottom, with two side walls of the bracket base, main arch wire groove is formed between the two side wall and the upper end of the bracket body, two side walls are respectively provided with ligation wings, set the outer surface the two side walls of the slopes, the side wall of ligation to the bracket along the direction of the matrix wing wall thickness decreases gradually in the ligation wings and the side wall is provided with a recessed junction. The present invention improves the existing ordinary brackets, in order to reduce the friction effect in the premise of the traditional mode of operation does not change the clinicians, and changes in the late treatment does not exist on the existing self-locking brackets to achieve precise control, and the sealing cover is often due to food residue or mosaic defects cannot be opened or closed open after deformation.
