Description
Technical field
The utility model belongs to dental orthodontic equipment technical field, and in particular to a kind of active self-locking with spring groove bottom
Bracket.
Background technology
One higher subdiscipline of degree of specialization of dental field when orthodontic treatment, self-ligating orthodontic bracket is in correction
In treatment, it is fixed on device made of the materials such as a kind of metal or the ceramics of dental surface with a kind of dedicated bonding agent, is used for
Receiving and Fixed Orthodontics arch wire, pass to tooth, to achieve the purpose that orthodontic by Orthodontic force.Traditional orthodontic bracket needs
Arch wire is fixed together with finer wire or rubber ring, clinical manipulation is time-consuming longer, inconvenient for operation, and orthodontic wire and support
Frictional force between slot is larger, and comfort level is poor, can extend the time rescued.Locking bracket is in the end of the seventies in last century in foreign countries
Gradually it is applied to clinic, compared with traditional fixed appliance, locking bracket saves the operating procedure of ligation arch wire, creates
Low friction low force rescues environment so that tooth movement under low force is possibly realized, and is rescued to play low force, patient comfort
High, tooth efficiently moves under physiological environment, is conducive to the features such as doctor controls anchorage.
Locking bracket generally can be divided into passive and active two major classes：1. the locking plate of passive type locking bracket is not deposited with correction silk
It is contacting, is being conducive to the movement that correction silk slides in groove and then controls tooth, most of locking brackets are using passive at present
Formula structure has effectively played passive type locking bracket and has been conducive to come into line leveling denture in the low-frictional force environment for rescuing creation early period
The advantages of；2. active locking bracket makes arch wire be embedded in bracket groove using elastic movable part, this elastomeric element is by arch wire
Be limited in bracket, while can store and gradually release energy, transmit and continue low force and arrive tooth and support construction, generate it is accurate with
Controllable movement, to effectively torque expression of the control tooth in groove.The restitution of elastomeric element is exactly by itself
And the tooth followed carries out the ability of three-dimensional redirection, until arch wire is completely into bracket groove-one's own department or unit.Tooth moving process
In it is any torsion, tilt and torque all will cause lip side elastomeric element deformation generate restitution.
The utility model patent of China patent No. CN203619700 discloses a kind of locking bracket, and the bracket is using sliding
Connection and it is semicircle close hole slot, have the characteristics that sliding plate switch is convenient, locking by force and rescues that the operating time is short, effect is good.
But currently, the elastomeric element used in such active locking bracket is mainly spring clip or spring clip.More
After secondary use, elastic recovery capability gradually weakens, and can not generate accurate and controllable torque expression again, and in extreme feelings
It also occur that phenomenon of rupture, causes malpractice under condition.

Right angle inwardly is opposite, is highly 0.3mm-0.4mm.
The spring is compression spring, and height is 0.5mm-0.6mm, and the center line of spring is located at spring groove bottom archwire slot
On horizontal center line, spring outer rim and the outer rim of spring groove bottom archwire slot are tangent；The length of the bracket plate is bent with spring groove bottom
The equal length of silk slot, the width of bracket plate is less than the width of spring groove bottom archwire slot, and thickness is 0.1mm.
Tie wings include sliding groove, limiting lock catching groove, protrusion and slide lock tabs；Wherein slide lock tabs one end, which is equipped with, opens
Hole slot, the other end, which is equipped with, closes hole slot.And semi-circular projection is provided in slide lock tabs, it is corresponding with the protrusion in limiting lock catching groove,
Bracket is set to achieve the purpose that self-locking.
Described slide lock tabs one end, which is equipped with, opens hole slot, and the other end, which is equipped with, closes hole slot.Instrumental purpose is facilitated to be closed in diamond shape
Closed pore slot realizes the closing of slide lock tabs.Or instrumental purpose opens hole slot in straight trough shape, realizes the opening of slide lock tabs
Preferably, bracket base is intermediate high, the low camber line structure in both ends.
The utility model has the beneficial effects that providing a kind of elastic stability, highly practical orthodontic active self-locking bracket
Slot, the locking bracket have torque that is simple in structure, easy to operate, can generating controllable precise, save the operating time by chair
The high feature with patient comfort.
