Embodiment 1

[0037] Embodiment 1: as Figure 8 As shown in a to 8d, the groove width of the self-ligating bracket is 0.018 inches, and the main angle of the bracket is Roth type. In the early stage of treatment, the 0.012-inch, 0.014-inch, and 0.016-inch nickel-titanium circular arch wires were placed in the bracket groove in turn, the sliding locking plate was closed, and the screw rotation switch was used to adjust the distance between the sliding locking plate and the nickel-titanium circular arch wire. The gap allows the nickel-titanium round archwire to slide freely in the groove. In the later stage of treatment, place 0.016×0.022 inches, 0.017×0.022 inches, and 0.018×0.025 inches of nickel-titanium square archwires into the bracket groove in turn, close the sliding locking plate, and turn the screw switch to close the connection between the sliding locking plate and the nickel-titanium square archwire. The gap between them makes the square archwire accurately express the torque in t...

Embodiment 2

[0038] Embodiment 2: as Figure 9 As shown in a to 9d, the groove width of self-ligating brackets is 0.020 inches for incisors, and 0.022 inches for other teeth. The main angle of the brackets is selected as shown in the table below. In the early stage of treatment, place the 0.012-inch, 0.014-inch, 0.016-inch, and 0.018-inch nickel-titanium round archwires into the bracket groove in turn, close the sliding locking plate, and use the screw rotation switch to adjust the sliding locking plate and the nickel-titanium circular archwire. The gap between the nickel-titanium circular archwires slides freely in the groove. In the later stage of treatment, place 0.016×0.016 inches, 0.017×0.022 inches, and 0.018×0.022 inches of nickel-titanium square archwires into the bracket groove in turn, close the sliding locking plate, and turn the screw switch to close the connection between the sliding locking plate and the nickel-titanium square archwire. The gap between them makes the square ...

Embodiment 3

[0041] Embodiment 3: The groove width of the self-locking bracket is selected as 0.022 inches, and the angle of the main body of the bracket is selected as MBT type. In the early stage of treatment, place the 0.012-inch, 0.014-inch, 0.016-inch, and 0.018-inch nickel-titanium round archwires into the bracket groove in turn, close the sliding locking plate, and use the screw rotation switch to adjust the sliding locking plate and the nickel-titanium circular archwire. The gap between the nickel-titanium circular archwires slides freely in the groove. In the later stage of treatment, place 0.016×0.022 inches, 0.017×0.025 inches, and 0.018×0.025 inches of nickel-titanium square archwires into the bracket groove in turn, close the sliding locking piece, and turn the screw switch to close the connection between the sliding locking piece and the nickel-titanium square archwire. The gap between the nickel-titanium square archwires can accurately express the torque in the groove. In t...

Abstract

The invention belongs to the field of an orthodontic medical appliance, and particularly relates to a movable self-locking support groove capable of regulating a gap with an arch wire and a tooth correction method thereof. The support groove comprises a support groove main body with different groove widths, a base and a sliding lock sheet, wherein the base is mechanically matched with the support groove main body in a movably dismountable way; the sliding lock sheet is arranged in the support groove main body; one end of the sliding lock sheet is provided with a screw rotating switch, and is used for regulating the gap between the bottom of the sliding lock sheet and the arch wire. The method comprises the following steps of according to different correction treatment stages, different support groove widths, torque angles, axial inclination angles and the arch wire in the required dimension are selected; the gap in the vertical direction and the horizontal direction is regulated; the low-friction environment in which the arch wire freely slides in the groove and the torque expression environment are created; by using the circular arch wire, the fast and regular arrangement of the teeth can be realized; by using the square arch wire, the torque expression and precise regulation and control of the tooth occlusion relationship can be realized; a personalized correcting appliance is provided for clinics; the movable self-locking support groove has the characteristics that the operation is convenient; the operation time beside a chair is reduced; the three-dimensional movement of the teeth is precisely controlled.

Description

technical field [0001] The invention belongs to the field of orthodontic medical devices, in particular to a movable self-locking bracket with an adjustable gap with an arch wire and a tooth correction method thereof. Background technique [0002] The self-locking bracket effectively reduces the frictional resistance of the arch wire sliding in the bracket, thereby improving the alignment speed of the teeth in the early stage of orthodontic treatment, and closing the locking piece is easy and simple, saving the orthodontist's chairside time for ligating the arch wire. Although some early clinical trials showed that self-ligating brackets are more effective in aligning teeth, subsequent higher prospective randomized clinical trials did not find that self-ligating brackets significantly shortened the treatment time during the entire treatment process. The reason is that Because most of the structural design flaws of self-ligating bracket appliances do not provide orthodontists...
