Description
Technical field
The invention belongs to mouth cavity orthodontic the field of medical instrument technology, more particularly to a kind of self-locking bracket for tooth orthodontic and knowledge
Other method.
Background technology
The open-close ways that locking bracket in the prior art mainly uses is slide switchings, and slide switching is generally using crowded
Nip drum axis is matched with locking blind hole, and squeezing roller bearing has elasticity, when locking plate promotes, is squeezed roller bearing and is pushed over and be extruded to
It is realized in locking blind hole sealed.Most of the installation of self-locking bracket for tooth orthodontic in the prior art is to take locking plate towards tooth
The direction of root is opened, and traditional bracket completes the fixation of bracket only with a main arch wire.Thus it will produce as follows
Both sides problem：
First, fix bracket using a main arch wire, in face of the serious patient of deformity teeth, it is possible that due to
The especially severe of a few deformity teeths of patient and cause bracket fix failure the case where.Meanwhile even for general tooth
The patient of deformity, is fixed tooth using a main arch wire, can also apply larger stress to tooth, be easy that patient is made to generate
Sense of discomfort.
Second is that when locking plate is opened towards teeth roots, locking plate can generate interference with the gum of teeth roots, stimulate tooth
Gum makes us generating sense of discomfort.For swelling and aching of gum patient, the dismounting of locking plate is even more that will produce difficulty.In donning process usually
In, since the folding direction of locking plate is consistent with the direction that is engaged of tooth, having certain probability causes locking plate in hard food
It is opened under the friction of object, and then bracket generates the phenomenon that loosening.
Due to the orthodontic bracket of the prior art, equipped with without draw hook, nearly middle band draw hook, remote middle band draw hook multiple types
Type.Doctor can need to be used without draw hook in use according to specific case scenario, nearly middle band draw hook, remote middle band
The several types such as draw hook, thus need individually to be chosen without draw hook bracket according to different cases, nearly middle band draw hook support
Slot or it is remote in the bracket with draw hook, bring many unnecessary troubles, and the draw hook carried on bracket to doctor
Without using when can influence in oral cavity the comfort level of patient.
The bracket for orthodontic treatment of the prior art, bracket surface can go out upper left, lower-left, the right side that bracket uses with colored marking
Upper, bottom right four uses section, but does not make being specifically identified for some specific tooth position, Ya Yi in each section majority
It during use, needs oneself to go to recognize, waste time, while being also easy to obscure different brackets, and colored marking is adopted more
With pigment, to health, there is also certain influences.Upper specific tooth bit identification does on bracket base in Ye You producers, but holds in the palm
Slot is after being bonded on tooth, since bracket base can be covered with tooth surface contact, the mark on bracket, it has not been convenient to
Differentiation and inspection after the completion, it is also not intuitive.
Therefore, a kind of self-locking bracket for tooth orthodontic of prior art urgent need and recognition methods, to overcome in the prior art kind
Kind defect.
Invention content

Handle；The slide lock tabs are integrally rectangular, slidably connect with the sliding groove at the top of the supporter groove；The groove is set
It sets in the middle-distant direction centre position of the supporter groove, the groove runs through the supporter groove for placing arch wire, the groove
And the horizontal edge of the supporter groove is divided into the first flank and the second flank, the slide lock tabs are covered in the top of the groove；
The through-hole setting is in first flank, and the through-hole is for being arranged auxiliary bow pipe；After self-locking bracket for tooth orthodontic installation, institute
The first flank is stated close to teeth roots, is located at gum to side, the second flank is located at jaw to side far from teeth roots；First side
The wing or the second flank are equipped with first identifier structure, and the slide lock tabs are equipped with second identifier structure.
Preferably, the through-hole is square through hole, and the groove is rectangular groove, and the axis of the through-hole is parallel to described
The axis of groove.
Preferably, the slide lock tabs locking plate opening direction is from the first flank the second flank of direction.
Preferably, there are two draft gear putting hole, the draft gears for setting between the bottom plate and the supporter groove
Putting hole is located at the nearly middle side of supporter groove and remote middle side.
Preferably, the axial symmetry of two draft gear putting holes, the size one of two draft gear putting holes
It causes, the hook end of the draw hook built in two draft gear putting holes, the draw hook is fixed with the supporter groove to be connected
It connects.
A kind of identification method with above-mentioned self-locking bracket for tooth orthodontic comprising：Slide lock tabs will be engaged on supporter groove
One end be set as first identifier face, be set as second identifier face towards the one end in outside after slide lock tabs are engaged with supporter groove, lead to
The second identifier structure crossed the first identifier structure being arranged on first identifier face and be arranged on second identifier face, realizes different teeth
The mark of position bracket.
Preferably, the first identifier structure setting is on any one angle of first flank or the second flank, institute
First identifier structure is stated to judge the supporter groove in the upper left position of tooth, lower-left position, upper right position, bottom right position
Which position, by the second identifier structure come judge the supporter groove be mounted on the position which position.
Preferably, the first identifier structure is that shape identifies structure, and the second identifier structure is Digital ID structure.
Preferably, the shape mark structure can be selected from one kind in circular groove, rectangular, triangle, cross；Institute
Stating Digital ID structure can be selected from one kind in Arabic numerals, Roman number, English alphabet.
The beneficial effects of the invention are as follows：
1) it reduces using the probability for generating Occlusal interference when bouble-bow technology, improves comfort level.
2) Orthodontic force allows tooth to move and is preferably controlled closer to the impedance center of tooth when using bouble-bow technology
