Description
Technical Field
The invention relates to the technical field of tooth correction, in particular to a tooth orthodontic device and a using method thereof.
Background
For most orthodontic fixing appliances, orthodontic tooth movement mainly depends on elastic deformation of an arch wire to store force for moving the teeth, and the arch wire is connected with a bracket adhered to the teeth to transfer the appliance force to the teeth. For many years, the connection is mainly fixed through ligation, but the prior art mostly replaces the original bracket with the self-locking bracket, and the self-locking bracket replaces the ligature wire or the ligature ring to fix the arch wire with the locking cap, thereby greatly reducing the operation time beside the chair, simultaneously greatly reducing the friction force in the correction process, bringing more advantages for clinical orthodontics than the traditional bracket, thus being favored by vast orthodontics doctors and becoming wider in the clinical application of orthodontics.
However, when the self-locking bracket and the arch wire are used for orthodontic teeth, due to the self-locking characteristic of the self-locking bracket, huge resistance exists in a gap between the arch wire and the self-locking bracket, and the Kusy and the Whitley divide sliding resistance possibly generated in orthodontic arch wire treatment into 3 parts: 1. friction due to contact of the orthodontic archwire with the bracket surface; 2. binding, when the teeth move obliquely or the orthodontic archwire is bent, the corners of the orthodontic archwire and the bracket are in binding contact, so that the orthodontic archwire is prevented from applying correction force to the teeth; 3. when the contact part of the orthodontic archwire and the corners of the bracket is permanently deformed, a notch is formed; when such a gap occurs, the tooth will stop moving until such a gap is restored; so that the orthodontic effect cannot reach the expected ideal.
For the self-ligating bracket orthodontic devices commonly used in the current market, although the friction force of the orthodontic archwire is reduced, the binding between the orthodontic archwire and the bracket and the occurrence of gaps still can obstruct the orthodontic movement of teeth, so that the orthodontic effect is not ideal.
