Embodiment Construction

[0014] See Figure 1 ~ Figure 3 The orthodontic bracket of the embodiment of the present invention includes a base plate 1, a bracket body 2 and a torsion wing 7. A slot 3 is provided in the middle of the bracket body 2, and the outer side of the slot wall 4 of the slot 3 Along the outwardly extending ligation wings 5, the center of the groove 3 is a straight groove wall 41, both ends of the groove 3 are arc-shaped groove walls 42, the arc-shaped groove wall 42 Both ends of the groove 3 are trumpet-shaped, which can reduce the resistance of the notch between the bracket and the arch wire 9; one or both ends of the groove 3 are provided with a torsion wing 7 which is connected to the bracket body 2 Connection, so that the twisted teeth are more easily arranged, and the effect of dentition deformity correction is better.

[0015] The present invention can be provided with a spring clip 8 instead of wire ligation. The spring clip 8 cooperates with the ligation wing 5, and the arch ...

Abstract

The invention discloses a teeth orthodontic bracket, comprising a base plate and a bracket body, wherein the base plate is connected with the bracket body; a groove is arranged in the middle of the bracket body; ligation wings are arranged at the outer side of the groove wall of the groove; the groove comprises a straight groove wall and a circular arc groove wall; the circular arc groove wall is trumpet-shaped; one end or two ends of the groove are provided with twisted wings; and the twisted wings are connected with the bracket body. The teeth orthodontic bracket is also provided with a spring clamp which is matched with the ligation wings. The teeth orthodontic bracket has simple structure and reasonable design, the designed spring clamp is clamped on the groove wall and has no ligation resistance with an orthodontic wire, the two ends of the straight groove are designed to circular arc groove walls so as to reduce the frictional resistance between the bracket and the orthodontic wire, the teeth can move under smaller force, the bracket is beneficial to the quick alignment of the teeth, and the orthodontic treatment process is shortened; the twisted wings are matched with the single-wing bracket, and the elasticity of the orthodontic wire can be relatively increased, thereby leading the rotated teeth correction to be easier and leading the orthodontic effect to be better; and the orthodontic wire is fixed by the spring clamp, thereby being convenient in operation and shortening the operation time of the doctor.

Description

Technical field: [0001] The invention relates to a dental orthodontic bracket for correcting oral dentition deformities. Background technique: [0002] Orthodontic fixed appliance for deformity correction of oral dentition, it includes arch wire, orthodontic bracket and ligature wire. The orthodontic bracket includes a base plate and a bracket body. The middle of the bracket body is provided with a groove. The outer sides of the two walls of the groove are turned outwards to form ligation wings on both sides. The lower inner side of the ligation wings forms a ligation groove, and the arch The wire passes through the groove of each orthodontic bracket, and the knot wire goes around the knot groove under the ligation wings and connects the arch wire and the orthodontic bracket together. Because the grooves are mostly straight grooves The frictional resistance between the ditch wall, the arch wire and the orthodontic bracket is relatively large, which is not conducive to the moveme...
