Definitions

  • the utility model belongs to the field of medical instruments, and particularly relates to an improvement of a movable wing bracket for correcting teeth.
  • the existing orthodontic bracket structure is a bracket seat with a bottom surface and a tooth surface.
  • the surface of the bracket seat is provided with a slot.
  • the surface of the bracket seat separated by a slot is formed into a convex wing, and the convex wing
  • the outer side is provided with a ligation groove for easy ligation.
  • the bottom surface of the bracket is bonded to the teeth, and one surface of each tooth is bonded, and then an arch wire is placed in the slot, and the elastic force of the arch wire is used to correct the structure of each tooth.
  • the misaligned teeth are arranged in different ways and are also irregular. It is often difficult to fit the archwire into the slot of the bracket on each tooth surface.
  • the two movable wing brackets designed by the requester are firstly positioned on the bracket seat by the folding legs of the two convex wings, and the two convex wings are relatively movable to realize the purpose of adjusting the width of the slot. It is convenient for the archwire to be inserted; the second is that one of the convex wings and the bracket seat are connected to form a fixed convex wing, and the other is a dynamic convex wing.
  • the clinical application proves that the latter is more scientific, and the fixed wing is used as the reference for positioning.
  • the use of the moving wing to adjust the spacing of the slot is simple and easy to perform. However, since the interface between the fixed wing and the moving wing is a straight mouth structure, the arch wire is often difficult to enter the groove, and it is difficult to operate on a small tooth surface, and the time is long, which increases the pain of the corrected person.
  • the purpose of the utility model is to provide a bellows movable wing bracket, which is not only advantageous for installation and adjustment, but also has good effect.
  • a bellows movable wing bracket comprising a fixed wing with a bracket seat and a moving wing pivoted on the bracket seat, a fixed wing and a moving wing
  • a slot of adjustable pitch is formed, and the feature slot is: the slot of the slot and the wing or the wing are inclined.
  • the interfaces on both sides of the slot and the fixed wing and the wing are inclined to form a large bell mouth shape. Due to the wide entrance of the slot of the slot, the clinical archwire can smoothly enter the bell mouth and apply downward pressure.
  • the arch wire can drive the wing to slip through the force component of the inclined surface, the dynamic spacing of the slot is enlarged, and the arch wire enters the bottom of the groove; or if the tooth is dislocated, the arch wire can enter and be ligated at the bell mouth.
  • the gradual improvement of the tooth dislocation gradually slides into the groove along the slope of the bell mouth.
  • the utility model has the advantages of simple structure, a movable single wing and a slotted groove with a bell mouth, the groove spacing is not only adjustable but also easy to guide the archwire into the slot, and the clinical operation is convenient, and the archwire can be adjusted by adjusting the movable wing. Deformation, the appropriate orthodontic force to correct the malocclusion, clinically reduce the replacement of the archwire, reduce the clinical workload, and shorten the treatment time.
  • Fig. 1 An exploded view of the movable wing bracket
  • bracket bracket 11 wing 12 channel 1 13 - anti-slip pattern 2 - wing 2 - double pin 3 - ligation groove hook 4 inclined surface
  • a bellows movable wing bracket includes a fixed wing 11 with a bracket seat 1 and a movable wing 2 pivotally mounted on the bracket base 1.
  • the bracket seat 1 is made of steel. The material is pressed, and the moving wing 2 is bent and bent by a steel wire.
  • the bracket seat 1 is provided with a channel 12 for slidingly locking the double-pin 21 of the moving wing 2, and the moving wing 2 is formed by bending a steel wire.
  • the double pin 21 has a certain elasticity and is clamped in the channel 12 to ensure sliding and free fall.
  • the moving wing 2 and the fixed wing 11 have a ligating groove hook 3 opposite to facilitate positioning of the ligature.
  • the interface between the fixed wing 11 and the moving wing 2 has an inclined surface 4, which constitute a symmetrical bell mouth slot structure.
  • the bottom of the bracket seat 1 is provided with an anti-slip pattern 13 to increase adhesion to the tooth table. The adhesion of the face.
  • the structure is substantially the same as Figure 1, except that the moving wing 2 is also pressed from a steel material.
  • this is a reference schematic diagram before and after the archwire is inserted into the groove.
  • Clinically due to the undulation of the misaligned teeth, there is basically no state in which the archwire 6 is parallel with the slot 5 of the bracket seat, and the archwire 6 is slotted. There is a certain angle between the slot and the slotted slot 5, and the bell mouth can be used for greater fault tolerance.
  • the archwire 6 is only ligated at the flared slot of the slot, and after a period of correction, Slot correction until the correction is in place.
  • the archwire 6 is also difficult to enter the groove.
  • the archwire 6 is pressed against the bell mouth of the slot 5, and is pressed down slightly, and the archwire 6 can press the wing. 2 sliding, the width of the slot 7 is widened, making the archwire 6 easier to ligature.
  • the distance from the starting point of the inclined interface of the slot of the slot to the bottom of the slot is greater than 0.2 mm, as shown in Fig. 4A.
  • the dynamic matching structure of the movable wing 2 and the bracket seat 1 can also adopt a central single-pin structure, and a corresponding channel in the middle of the bracket seat is matched with the single channel.

Abstract

Patte à aile active en corolle évasée comprenant une aile immobile (11) combinée avec un élément de maintien de patte (1) et une aile mobile (2) montée pivotante sur cet élément (1) par coulisse. Une rainure en forme de“-”est formée entre les deux ailes (11, 2). L'espace de la rainure est réglable. Le plan d'interface de la rainure et de l'aile mobile (11) ou le plan d'interface de ladite rainure et de l'aile mobile (2) sont déclinants. Les deux plans d'interface qui sont formés par l'intersection de la rainure avec l'aile immobile (11) et l'aile mobile (2) sont déclinants, de manière à former une corolle évasée, dont l'extrémité supérieure est grande et dont l'extrémité inférieure est petite.
