Abstract

This model utility relates to a bell mouth-type bracket with movable wings and includes a fixed wing integrated with a bracket base and a movable wing with a glide hinge set on the bracket base, a horizontal groove with adjustable spacing between the fixed wing and the movable wing, which is characterized that at least one side of the interface between the fixed wing and the movable wing must be inclined and the horizontal groove mouth between the fixed wing and the movable wing is a bell mouth structure. This model utility has a simple structure, has both movable single wing and a horizontal groove with a bell mouth structure, the spacing between grooves are not only adjustable, but also easy for introducing arch wires, the clinical operations are convenient, the distortion of the arch wires can be adjusted by adjusting the movable wing, the resulted correction forces can adjust the malposition teeth so as to reduce replacement of arch wires, reduce the clinical working loads and also shorten the treatment period.

Description

The horn mouth Support slot with movable wings

Technical field:

This utility model belongs to the medical apparatus field, particularly a kind of improvement of Support slot with movable wings of straightening of teeth.

Background technology:

Existing orthodontics bracket structure is the bracket seat that a bottom surface and the flank of tooth match, and the surface of bracket seat offers flat recess, and the bracket seating face that flat recess separates forms the protruding wing naturally, and the outside of the protruding wing offers the ligation groove, is convenient to ligation.During use, the bracket bottom surface is bonded on the tooth, one of each facing bonding is pacified an arch wire in the flat recess then, uses the structure of each malposed tooth of elastic force traction correcting of arch wire.The arrangement of malposed tooth is different, and is also random, often is difficult to arch wire is pacified in the bracket flat recess on each facing.Two Support slot with movable wings that this claimant formerly designs, the folding foot of the first two protruding wings is folded on the bracket seat locatees, forming the two protruding wings can relatively move, and realizes the broad-adjustable purpose of flat recess, be convenient to arch wire pacify into; Two to be protruding wings become the fixed protruding wing with bracket seat disjunctor for it, and another becomes the moving protruding wing of dynamic fit.Utilization clinically facts have proved that the latter is science more, decides the wing as localized benchmark, and utilizes the moving wing to regulate the spacing of flat recess, and the ligation operation is also simple.But owing to decide the interface of the wing and the moving wing is straight mouth structure, and arch wire often is difficult to into groove, and big in small dental surface operation easier, the time is long, increases by rectifier's misery.

Summary of the invention:

The purpose of this utility model is the movable slippage of a kind of single-blade of design, and the flat recess that the two protruding wings are constituted has bell-mouthed Support slot with movable wings.

Technical solutions of the utility model are achieved in that a kind of horn mouth Support slot with movable wings, comprise that a disjunctor has the decide wing and slide pivot of bracket seat to be located at the moving wing on the bracket seat, decide the wing and the moving adjustable flat recess of interplane formation one spacing, it is characterized in that at least becoming skewed with one of moving wing interface side deciding the wing, the flat recess notch of Gou Chenging becomes the horn mouth structure between the two.Because flat recess horn mouth inlet broad, arch wire can enter the horn mouth place smoothly clinically, slightly executes downward pressure, and arch wire can drive moving wing slip by the component on inclined-plane and move, and it is big that the flat recess dynamic space becomes, and arch wire enters bottom land; Perhaps to the transposition of teeth severe patient, arch wire can be introduced into and ligation at the horn mouth place, the progressively improvement along with transposition of teeth slips in the groove along the horn mouth inclined-plane gradually.

The utlity model has simple in structure, both had movable single-blade, have bell-mouthed flat recess again, separation not only scalable and easier guiding arch wire is gone into groove, and clinical manipulation is convenient, can adjust the distortion of arch wire by regulating movable wing, produce the suitable power of rescuing and rescue malposed tooth, make to reduce clinically and replace arch wire, alleviated the clinical position amount, also shortened treatment time.

The specific embodiment:

With reference to Fig. 1, a kind of horn mouth Support slot with movable wings, comprise that a disjunctor has the decide wing 11 and slide pivot of bracket seat 1 to be located at the moving wing 2 on the bracket seat 1, bracket seat 1 is formed by the steel material compacting, the moving wing 2 is folded by the steel wire bending, offers on the bracket seat 1 to form because the moving wing 2 adopts steel wire to bend for moving the conduit 12 that 2 pairs of pins of the wing 21 slide and are pivoted, its pair pin 21 has certain elasticity, be folded in conduit 12, can guarantee to slide freely, again difficult drop-off.The moving wing 2 and decide that the wing 11 is opposing to have a ligation groove hook 3 makes things convenient for the location of ligature.All have inclined plane 4 and decide the wing 11 with the moving wing 2 interfaces, both constitute symmetrical horn mouth flat recess structure.Bracket seat 1 bottom is provided with anti-skidding stricture of vagina 13, can increase the cohesive force attached to tooth surface.

With reference to Fig. 2 and Fig. 3, this structure is basic identical with Fig. 1, and the just moving wing 2 is also formed by the steel material compacting.

With reference to Fig. 4 and Fig. 5, this is the reference view that arch wire is gone into the groove front and back, clinically because the fluctuating of malposed tooth between cog is indefinite, substantially there is not the parallel state of arch wire 6 and bracket seat flat recess 5, when arch wire 6 is gone into groove and flat recess 5 have certain included angle, can utilize horn mouth to have bigger fault-tolerant ability this moment, 6 of arch wires are by being located at the horn mouth place ligation of notch broad, after waiting to correct a period of time, progressively go into the groove rectification again and put in place until rectification.

In addition then, tradition clinically, arch wire 6 also is to be difficult to go into groove, in this structure, arch wire 6 is lower pressed against the horn mouth place of flat recess 5, arch wire 6 can be oppressed the moving wing 2 and be slided, flat recess 5 width broaden, and make that arch wire 6 is easier goes into interior ligation.In order to guarantee that flat recess 5 has certain restraining forces, reaching the need of final rectification, the distance of the skewed starting point of 5 liang of interfaces of flat recess at the bottom of the flat recess is greater than 0.2mm, as Fig. 4 A section.

The dynamic fit structure of the moving wing 2 and bracket seat 1 can also adopt the single pin configuration in middle part except that last two legends, the corresponding single cavity road that cooperates with it that offers at the middle part on its bracket seat.

Claims

1, a kind of horn mouth Support slot with movable wings, comprise that a disjunctor has the decide wing and slide pivot of bracket seat to be located at the moving wing on the bracket seat, decide the wing and the moving adjustable flat recess of interplane formation one spacing, it is characterized in that at least becoming skewed with one of moving wing interface side deciding the wing, the flat recess notch of Gou Chenging becomes the horn mouth structure between the two.

2, horn mouth Support slot with movable wings according to claim 1 is characterized in that deciding the wing and all becomes skewed with moving wing interface, and both constitute symmetrical horn mouth flat recess.

3, horn mouth Support slot with movable wings according to claim 1 and 2 is characterized in that the distance of the skewed starting point of interface at the bottom of the flat recess is greater than 0.2mm.
