Head first to its neighbouring tie wings direction bend, then to the tie wings closed on away from it direction bend.
Preferably, described bracket is single-blade hook bracket or double-vane hook bracket, when bracket is double-vane hook bracket, with bow
Silk groove is intersecting to be provided with bracket mouth.
In order that reed will not infinitely insert to same direction, preferably, described reed is integrally T-shaped, its head
Wider, afterbody is narrower, and the outline on reed head is smooth curve shape.The outline on reed head is smooth curve shape, mainly
It is more smooth in order to coordinate with secondary arch wire, it is reduced as far as possible when slipping into and hinder.
A kind of preparation method of bracket for orthodontic treatment, pacify on supporter groove below the tie wings of the main any one side of arch wire groove
A flexible reed is put, secondary arch wire groove is formed between the adjacent tie wings of reed, the head of reed is adjacent
Tie wings between space be secondary arch wire groove notch.
Preferably, the lower section of main arch wire groove is processed always by wire cutting or powder metallurgic method on supporter groove
The slot of logical supporter groove, described slot are that direction setting is intersected on edge with main arch wire groove, and reed is inserted into slot, bracket afterbody
Bending is carried out after exposing supporter groove.
Preferably, the head of reed is in smooth curved surface shape.
The design philosophy of the invention and beneficial effect for employing above-mentioned technical proposal be:
Supporter groove cost of the present invention is low, easy to make, wire cutting can be used to shape, it is also possible to which powder metallurgy or casting add
Work.Only need based on common bracket, slightly improve;At orthodontic initial stage, only secondary arch wire need to be caught in secondary arch wire
In groove, the troublesome operation of steel ligature is eliminated.It will not directly force in bow as steel ligature or ligation rubber ring again
Silk, therefore do not interfere with normal movement of the arch wire during orthodontic treatment so that orthodontic treatment effect is faster and better.Meanwhile should
Secondary arch wire groove make use of the underlying space of tie wings on supporter groove, does not increase supporter groove height, makes patient more comfortable, and
Make bracket be less susceptible to Off to fall.It is more convenient than the locking bracket using main arch wire as self-locking, more reliable.Simultaneously in the correction later stage, by
In cetlin double arch wire effect, make correction faster, it is more efficient.
The secondary arch wire groove design of the present invention is to be cooperatively formed by an elastic reed with tie wings, reed stress
Deformation can be produced and resetted when external force disappears, the secondary archwire slot ditch notch is small, and inner space is big, and reed only needs low force so that
Secondary arch wire groove has auto-lock function.Simultaneously because the notch direction of the secondary arch wire groove is parallel with facing, with secondary arch wire by
Power is vertical, so secondary arch wire is fairly small in power of the timing along disengaging notch direction, the reed on so secondary arch wire groove only needs
Doctor is born to be put into secondary arch wire or skid off the power of secondary arch wire, and timing along pass in and out secondary archwire slot ditch notch direction hardly by
Power, so the reed only needs the power of very little to realize auto-lock function.
At orthodontic initial stage, secondary arch wire is slipped into along parallel to main arch wire groove direction by the notch of secondary arch wire groove
Secondary arch wire groove, acted on by secondary arch wire to reach the purpose of orthodontic correction at initial stage;At correction initial stage, using main arch wire with
Secondary arch wire effect is the same, and the secondary arch wire of the present invention, because it is self-locking, so being self-locking in this stage and main arch wire
Effect is the same;In the orthodontic later stage, main arch wire is put into main arch wire groove, and if do not have to secondary arch wire now, then pair bow
Silk groove is equivalent to the lower space of tie wings, and the bracket is equivalent to a common bracket.And if now with secondary arch wire, then
The slot-open-section of secondary arch wire groove can also ligature, and so can ligature major and minor arch wire simultaneously, have cetlin double arch wire effect, accelerate just
Abnormal effect, save the correction time.
Further say, secondary arch wire groove was processed by wire cutting or powder metallurgy directly in tie wings in the past, i.e.,
Secondary arch wire groove is enclosed, it is therefore necessary to it is to be penetrated with secondary arch wire to realize, and it is in fact so empty in so small oral cavity
Interior penetrate is not part nothing the matter, so it is very inconvenient that secondary arch wire, which uses,;It is compared with the past, because of the pair of the present invention
Arch wire is self-locking form, is to enter secondary arch wire groove using slipping into mode, thus it is more convenient to operate.
