Embodiment 1

[0028] Embodiment 1: The groove width of the metal self-locking bracket is 0.022 inches, and the spring clip is NiTi alloy. If the aesthetic effect of the maxillary premolars can be seen in the orthodontic effect, the root positioning of the maxillary premolars is corrected so that it is in a 90° vertical state on the alveolar bone surface, and the angle of the self-ligating bracket is shown in Table 1. Show. In Table 1, UR stands for Upper / Right, UL stands for Upper / Lower, LR stands for Lower / Right, LL stands for Lower / Left, and the Arabic numerals behind UR / UL / LR / LL represent tooth position codes . For example, UL3 means the third tooth on the upper left.

[0029] Such as Figure 4 As shown in a to 4b, the self-ligating bracket bottom plate with the bottom net is bonded to the teeth, the spring clamp lock plate is opened, and the round cross-section arch wire with a suitable specification and size is selected in the early stage of orthodontic treatment, and its diameter i...

Embodiment 2

[0033] Embodiment 2: The groove width of the metal self-locking bracket is 0.022 inches, and the spring clip is medical stainless steel. If the malocclusion teeth are Angle II, it is generally necessary to use high-torque brackets in the upper jaw, and use standard torque or low-torque brackets in the lower jaw to resist the force of elastic traction or intraoral devices. The angles of the self-locking brackets are shown in Table 2, and the selection of matching archwires and the connection of the self-locking bracket spring clip locking pieces to different step interface positions are the same as those in Embodiment 1.

Embodiment 3

[0036] Embodiment 3: The groove width of the metal self-locking bracket is 0.018 inch, and the spring clip is medical stainless steel. If the malocclusion teeth are Angle’s class III, it is generally necessary to use low-torque brackets for the upper jaw and high-torque brackets for the lower jaw to resist elastic traction. The angles of the self-locking brackets are shown in Table 3, and the selection of matching archwires and the connection of the self-locking bracket spring clip locking pieces to different step interface positions are the same as those in Example 1.

Abstract

The invention belongs to the field of orthodontic medical instruments, and particularly relates to a self-ligating bracket for tooth correction and a use method of the self-ligating bracket. The self-ligating bracket is characterized in that the self-ligating bracket comprises a bottom net, a bottom plate, a bracket body and a spring clamp locking sheet; the bottom net is arranged on the bottom plate, the bracket body and the bottom plate are fixedly mounted, a groove is formed in the middle of the bracket body, an upper step connector and a lower step connector are formed in one side of the wall of the groove, and the structure is suitable for different tooth jaw relations; the spring clamp locking sheet is of a C type structure, the lower end of the spring clamp locking sheet penetrates through the bracket body, and the upper end of the spring clamp locking sheet covers the bracket body to be connected into the upper step connector or the lower step connector; the shaft inclination angle and torque angle of the self-ligating bracket are designed according to the different malocclusion degrees of patients. According to the individual self-ligating bracket, four steps of traditional correction are adjusted and simplified into two stages, the process that an arch wire knot pricks into the bracket is simplified, and the complex operation of frequently replacing arch wires in the traditional correction process is greatly omitted.

Description

technical field [0001] The patent of the invention belongs to the field of orthodontic medical devices, and specifically relates to a self-locking bracket for orthodontic treatment. Background technique [0002] Self-locking brackets provide the possibility for light-force orthodontics by simplifying the way of ligating the archwire into the bracket, reducing the frictional resistance of the archwire sliding in the bracket, and improving the efficiency of orthodontic treatment. At present, the structural forms of self-ligating brackets are divided into: active type, passive type, and interactive type. Active self-locking brackets use spring clips to exert active pressure on the arch wire, which is beneficial to control the torque of the teeth to adjust the ideal dental arch shape. Since the self-locking cover of the passive self-locking bracket does not squeeze the arch wire, the friction between the two is reduced and the arch wire slides in the bracket. Interactive self-...
