A kind of self-locking bracket for tooth orthodontic with slide lock tabs

Technical field

This utility model belongs to the orthodontic apparatus field, specifically is meant the bracket that a kind of orthodontic is used.

Technical background

Main at present use ligature of steel wire of Buccodental orthodontic treatment or rubber ring ligation, these two kinds of ligation generally all directly force in arch wire, and arch wire is produced bigger pressure, have hindered the normal of arch wire to move, and influence the effect of orthodontic treatment easily.At this problem, Chinese patent ZL200620105725.8 discloses a kind of bracket structure, the length of the work that the is shorter in length than groove of its tie wings, so steel ligature or rubber ring no longer directly force in arch wire, arch wire can normally move.But the orthodontic bracket of this structure is still kept away unavoidable loaded down with trivial details steel wire or rubber ring ligation process.

Summary of the invention

At the above defective that exists in the prior art, this utility model provides a kind of simple to operation and slide lock tabs can firmly be locked in the self-locking bracket for tooth orthodontic of archwire slot top.

The technical solution adopted in the utility model is as follows: a kind of self-locking bracket for tooth orthodontic with slide lock tabs, comprise substrate plate and supporter groove with archwire slot, the archwire slot both sides are provided with the work wing, and one of them work wing is provided with a T type groove, is provided with a slide lock tabs in the T type groove; The lower surface of slide lock tabs is provided with the locking foot, and corresponding T type groove groove bottom is provided with the locking hole that cooperates with the locking foot, and locking hole is that two squeeze feet are around the non-blind hole that forms; The both sides of locking foot are respectively arranged with locating piece, and corresponding T type groove groove bottom is provided with the locating hole that cooperates with locating piece, and locating piece is limited in the locating hole and slides.

Self-locking bracket for tooth orthodontic with slide lock tabs of the present utility model, the work wing of the described T of setting type groove is provided with boss along the extension of archwire slot side.

Self-locking bracket for tooth orthodontic with slide lock tabs of the present utility model, described slide lock tabs upper surface is provided with a shrinkage pool.

Self-locking bracket for tooth orthodontic with slide lock tabs of the present utility model, wherein a work wing piece is provided with hook.

Self-locking bracket for tooth orthodontic with slide lock tabs of the present utility model, substrate plate are the net bottom substrate plate.

The following advantage that the utlity model has:

1, owing to adopt the slide lock tabs structure,, arch wire can be positioned in the work nest as long as the locking foot of slide lock tabs is advanced locking hole, simple to operation, the troublesome operation of having removed the ligation silk from.Simultaneously can as steel ligature or rubber ring, directly not force in arch wire again,, make orthodontic treatment reach better effect so can not influence normal the moving of arch wire in the orthodontic treatment process.

2, owing to also be provided with locating piece on the slide lock tabs, and locating piece is limited in the locating hole and slides up and down, so can make slide lock tabs not produce left and right displacement, firm is locked on the archwire slot.
