Description
Technical Field
The utility model relates to an just abnormal technical field, concretely relates to high-efficient plane just abnormal support groove of opening interlock.
Background
The common oral orthodontic appliance includes fixed appliance and invisible appliance. The fixed correction is more advantageous in maintaining the stability of the occlusal plane and the anchorage protection, but the teeth are required to be aligned by the soft arch wire and can be moved greatly by gradually replacing the soft arch wire with the hard arch wire. The invisible appliance has the advantage that the gap can be closed to move teeth in the early stage, but because the actual tooth movement is different from the step pitch of the appliance design, the invisible appliance needs to be restarted repeatedly in the later stage to adjust a treatment plan, so that the treatment course is obviously increased; in addition, for the invisible orthodontic tooth extraction case, after the tooth extraction gap is closed, the occlusion plane is often folded, the long axis of the tooth is easy to be abnormal, and the time consumption is long through restarting and correcting.
The three-dimensional printing technology can be used for manufacturing personalized bracket according to the tooth surface shape and the ideal dentition model, so that the curative effect is obviously improved, the treatment course is shortened, and the seamless connection of invisible correction and fixed correction can be realized. In existing fixed orthodontic systems, archwires (square wires) are typically slotted in a vertical longitudinal manner, which is more difficult to provide adequate support to the occlusal plane. Compared with the traditional square wire arch and straight wire arch correction devices, the contact area between the arch wire which is inserted into the groove by the wide labial lingual direction and the bracket is reduced, the friction force is reduced, and the correction efficiency is increased; meanwhile, the ribbon bow system with the rigidity enhanced vertically upwards can enhance the open occlusion and is helpful for maintaining the stability of the occlusion plane. The ligation wings of the ligation bracket which is matched with the correction system for use at present are relatively sharp and weak, the ligation wings are easy to break, and food residues and dental calculus are easy to accumulate; and the groove is mostly the cambered surface of laminating with the tooth face, demolish the degree of difficulty great, more take time.
