Description

Ribbon straight wire bracket

Technical field:

The utility model relates to an orthodontic fixed correction device for correcting dental and jaw deformities, in particular to a belt-shaped straight wire arch bracket capable of realizing automatic torque and fully synchronous tooth movement.

Background technique:

The basic structural form of the current orthodontic fixed aligner is the traditional square wire arch aligner structure, and a straight wire arch groove structure that eliminates three-sequence bending is added to the bracket groove. The common feature is that the groove is designed as an opening The transverse groove toward the lip and buccal direction, the cross section of the groove is a rectangle whose upper and lower heights are narrower than the depth of the groove, and is used to incorporate the corrective archwire that bends the narrow side with the wide side as the plane, which is commonly called square silk bow. In order to eliminate the third-order bending of the traditional square wire arch, the torque structure designed on the groove is located on the upper and lower sides of the groove, and the labial-lingual torque movement of the teeth is realized through the torque of the archwire and the upper and lower sides. This structural feature makes the square wire arch with rectangular cross-section unable to give full play to the mechanical properties of the arch wire during the orthodontic movement, and cannot exert ideal elasticity in the tooth alignment movement that requires elasticity, and needs to use other elastic arch wire materials Perform separate alignment; in the anteroposterior control of the dentition that requires rigidity of the archwire, the required rigidity cannot be met. The torque movement generated by it cannot be reasonably utilized due to the performance of the archwire, and it is difficult to achieve the predetermined torque tooth movement, and an auxiliary archwire is often required. Therefore, the orthodontics of the currently used fixed orthodontics need to be carried out step by step, that is, alignment, adduction, torque, etc., which makes the clinical orthodontic efficiency low.

Invention content:

In order to solve the unreasonable structural performance of the traditional bracket groove and the rectangular cross-section square wire arch, the bracket of the utility model changes the groove structure so that it can play the structural performance of the groove and the square wire arch more reasonably to achieve The orthodontic effect of automatic torque and fully synchronized tooth movement can improve clinical work efficiency.

The technical scheme that the utility model solves its technical problem adopts is:

The utility model belt-shaped straight wire arch bracket is characterized in that: the bracket includes a bottom plate and a bracket main body arranged on the bottom plate, the bracket main body is horizontally provided with a bracket groove with a rectangular cross-section, the The bottom surface of the bracket groove and the surface of the bottom plate form a preset torque, and the strip-shaped archwire is arranged in the bracket groove, and the wide surface of the strip-shaped archwire is attached to the bottom surface of the groove to generate automatic torque.

The groove height is greater than 0.025 inches, and the groove depth is less than or equal to 0.025 inches.

The utility model designs the cross-section of the groove so that the upper and lower height dimensions are greater than the inner and outer depths, so that it becomes a rectangular cross-sectional structure with a facade larger than the plane, specifically, the height of the groove opening is greater than 0.025 inches, and the groove depth is less than or equal to 0.025 inches. Inch, and preset torque degree on the bottom of the groove, to incorporate the strip-shaped square wire arch that bends the wide surface with the narrow surface as the plane, that is, the strip-shaped archwire, so that the formation of the strip-shaped archwire and the groove is optimized fixed orthotic structure. Through the ligation of this structure, when the bottom surface of the groove fits the wide surface of the tape-shaped archwire, the automatic torque movement of the tooth can be realized, and the expression of the preset torque can be more accurate than that of the existing bracket. On the other hand, the good elasticity of the strip-shaped arch wire in the labial-lingual direction of the dentition is conducive to the movement of aligning the teeth, and the rigidity of the arch wire in the anteroposterior direction of the dentition is conducive to controlling the stability of the occlusal plane and the opening of the overlay, so it can be used at the initial stage. The teeth are retracted from the beginning of the installation of the aligner, and the alignment and leveling of the teeth are achieved while retracting. The change of the bracket groove structure and its combination with the band-shaped arch can simultaneously perform various tooth movements such as alignment, adduction, and torque, thereby changing the alignment and leveling of the teeth when the existing fixed aligners correct the teeth. , adduction, and torque are carried out step by step in order. The utility model only needs to use one main arch wire, does not need to use an auxiliary arch, and rarely needs to replace the arch wire. So that the clinical operation is more simple and easy to master.

The beneficial effects of the utility model are: through the automatic torque mechanism and the fully synchronous tooth movement mechanism, the structure and performance mechanism of the fixed orthodontic device solve the problem that the tooth movement of the existing fixed orthodontic technology is carried out according to the inherent procedure, the efficiency is low, and the accuracy is not easy to control The problem. It reduces the complexity of clinical operations, improves the efficiency and accuracy of tooth movement, and shortens the period of clinical treatment.
