The force arc has ends engagingly mounted on the dental rings to enable engagement with supporting bushings to take place. The working bushings have slits for the force arc to be mounted. The force arc has 0.45-0.5 mm large diameter and length matching dental arc length. The kappa has three movable parts connected to each other through the force arc. The working bushings are fixed on oral surfaces of the movable parts. the working and supporting bushings are produced from metal or plastic material. EFFECT: improve engagement properties; enable individual fitting; simplified installation. 5 cl, 1 dwg
