The group of devices consists of rotator keys, active tips, support base, a cord and its anchor grip. Fastening forceps comprise the left lever and the right lever, active tips movable and retained in the fixed position, and springs. The springs apply pressure to the active tips while being inserted into holes of the two levers. Necks of the active tips are attached to cord ends. The spring is inserted into landing seats. A millimetre screw hole is formed at the distal end of the right lever of the forceps. When rotated, the millimetre screw extends through a millimetre nut. An adjustment knob is attached to a rotator.EFFECT: tooth can be removed unsupported on any of the proximal teeth.11 cl, 10 dwg |
