Embodiment Construction
[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0014] see Figure 1-2 , the present invention provides a technical solution: a new type of orthodontic appliance, including a base plate 4, a fixed block 2 is fixed on the middle position of the upper surface of the base plate 4 along the front-to-back direction, and a groove is opened on the upper surface of the fixed block 2 along the front-to-back direction Groove 8, the arch wire is placed in the groove 8, the friction between the groove 8 and the arch wi...

The invention discloses a novel orthodontic appliance which includes a bottom plate. A fixed piece is fixed to the center of an upper surface of the bottom plate in the forth and back direction. A trough is formed, in the forth and back direction, in the upper surface of the fixed piece. A through trough is formed, in the left and right direction, in the lower end of the fixed piece. A snapping apparatus is installed on the fixed piece and includes a slide plate, wherein an external bolt fastener drives a fastening bolt to rotate so as to fix the position of the snapping apparatus and prevent auto-movement thereof, so that the stability of the novel orthodontic appliance is improved. Two ends of an external tension spring are respectively connected to two vertical columns in the novel orthodontic appliance, wherein the external tension spring is used for drawing teeth and closing a gap, so that orthodontic effect of the novel orthodontic appliance is improved. The friction force between the trough and an arch wire is relatively low, so that when orthodontic force is too high, the arch wire is auto-released to avoid teeth damage and apical root resorption, thereby protecting teeth and periodontal health better.
Description
technical field [0001] The invention relates to the technical field of orthodontic treatment, in particular to a novel orthodontic appliance. Background technique [0002] Most of the orthodontic appliances in the prior art need to be ligated with the main arch wire through the ligature wire to achieve the orthodontic effect. The orthodontic self-locking appliance does not need to be ligated, but the snap-in device is easy to open by itself, which is inconvenient for patients to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a new type of orthodontic appliance, which drives the fastening bolts to rotate through the external bolt fixing parts, thereby fixing the position of the clamping device and preventing the clamping device from moving by itself , improve the stability of the new orthodontic appliance; the two ends of the external tension spring are respectively connect...
