[Application of the segmented arch technique in adult patient].

Abstract

The segmented arch technique has been developed with the three primary objectives; (1) force control over active and reactive teeth, (2) reduction in the number of chair hours required to treat a case, and (3) minimization of patient cooperation. The author experienced the efficiency and superiority of the segmented arch technique through the treatment of the Korean adult patient. With the possibility of accurately measuring the forces and moments delivered to tooth during orthodontic therapy, not only is it possible to improve the quality of orthodontic tooth movement, but it is also possible to learn about the nature of optimal forces that are needed clinically. A number of mechanisms have been described for initial levelling, deep overbite correction, anterior retraction, root movement and occlusal seating.
