【 摘 要 】

The shortening of a tooth arch is clinically shown by crowding. In the final period of a mixed bite, the place disadvantage for canines is often detected. The problem of elongation of a tooth arch due to distal movement of premolars, the first and second permanent molars on removable appliances is discussed. In practical orthodontia, this way of treatment of the shortened tooth arch traditionally solved only with use of the fixed equipment. The fixed equipment allows to control the made effort to each of the moved teeth. Power source in removable appliances are screws. When designing removable orthodontic appliances the area of the moved teeth and a possibility of force action of the used orthodontic screws on the moved group of teeth is considered. Maintenance of balance between the applied force and the area of roots of the moved teeth allows to reach optimization of process of reorganization of parodentium. The clinical case showing efficiency of removable appliances in a constant occlusion for elongation of a tooth arch is presented, their design is described.
