Description
Technical field
This utility model relates to a kind of dental orthodontic instrument field, is specifically related to carry on a kind of working wing the locking bracket of elastic ring snap close.
Background technology
Orthodontic treatment is a subdiscipline that degree of specialization is higher of dental field, mainly is to rescue for tooth, jawbone, facial deformity, by inner Fixed Orthodontics appliance recovers patient's normal occlusion function gradually in the oral cavity.Bracket is the important component part of orthodontic appliance, mainly is adhered on labial teeth, canine tooth, the premolars, and orthodontic treatment is installed in by rescuing arch wire in the groove of bracket, and the Tooth Movement of guiding dislocation is to desirable position.
The mode that traditional bracket adopts ligature or India rubber looper to prick is fixed in arch wire in the groove, but the shortcoming such as there is the time-consuming inconvenience of clinical manipulation in this fixed form, frictional force is large, level of comfort is poor.In recent years, locking bracket (self-ligating bracket) orthodontic treatment that appears as patho-occlusion of rescuing system has been introduced new method.The characteristics of locking bracket maximum are that the self-locking structure by bracket substitutes conventional junction tied silk (circle) arch wire is carried out ligation, have reduced the frictional force of orthodontic appliance inside, make to rescue efficient and significantly increase, and be a kind of quick, comfortable, safe fixed orthodontic device.At present, locking bracket with respect to traditional bracket have low-frictional force, reduce anchorage loss, improve clinical manipulation efficient, the patient is to the particular advantages of the aspects such as pain reaction is light, and the locking bracket engagement is stable, small and exquisite attractive in appearance, the patient wears with comfortable, easy to clean, Chairtime shortens, the further consultation interval prolongs, and it is shorter to rescue efficient height, the course for the treatment of.So that locking bracket obtains more and more just abnormal doctors' understanding and affirms.
Common locking bracket is slide way type structure (a passive slide) or locker formula structure (a spring clip).The slide way type bracket arranges slip lid in the groove both sides, includes arch wire in rear promotion slip lid and forms a closed conduct solid, that arch wire can move freely, claims again passive-type locking bracket (passive self-ligating bracket).The built-in high resiliency locker of locker formula bracket, the elastic pressure of closing rear generation can act on arch wire when needed, provides to continue soft orthodontic force, claims again active locking bracket (active self-ligating bracket).Because the self-locking device multidigit of locking bracket is in the bracket metal surface, convenient with instrument or finger tip switch, the ligation process is more easy.
Present most locking bracket itself has certain design defect, its slip lid or locker are opened under some unexpected factor affecting easily, can lose groove to the control of arch wire if slip lid or locker accident are opened, affect therapeutic effect, instead prolonged treatment time.And because the complicated structure of locking bracket, some external force (comprising masticatory force) and doctor's maloperation all may cause the damage of locking bracket, thereby cause slip lid or locker to open and to close, when serious even cause locking bracket to scrap, increase patient's financial burden, improved treatment cost.Again, the self-locking device of locking bracket occupies on the facing usually than large space, so that the thickness of locking bracket is larger, may come off when chewing, and therefore there is limitation in the relatively poor child of compliance and deep overbite patient's use.Simultaneously because the short and small circle of working wing of locking bracket is blunt, inconvenience of maintenance, easily slippage when adding the ligation adnexa, and inserting arch wire and taking out in the process of arch wire, locking bracket is compared with traditional double-vane bracket has great uncomfortable property, usually causes patient's pain.In addition, when using crooked Rectangular SS archwires to adjust individual teeth, arch wire difficulty in place and can't close slip lid or locker, these have all limited the use of traditional intense adjustment mode.
Chinese patent: the shape memory self-ligating orthodontic brackets (patent No.: 200580028504.3, the applying date: a part that 2005.07.01) discloses a kind of working wing is the locking bracket that can surrender, wherein locking bracket is provided with bracket base and one or more working wing, working wing comprises the pedestal that is connected with bracket base, and the groove that is recessed to form downwards by the pedestal center of top, groove is used for holding arch wire.Stretch out to offside on the top, two side of groove, forms the flange that extends in opposite directions to the groove top.The groove two side has certain surrender, and when the groove two side was relaxed state, the end of two flanges joined or approximate joining, thereby with the groove locking; When the groove two side relatively moves distortion, the arch wire entrance appears between the end of two flanges, can arch wire be inserted or shift out groove by this arch wire entrance.Because the groove two side of working wing relatively moves and when being out of shape under external force in this patent, just can open the arch wire entrance, therefore in clinical practice, the doctor need to apply in the two side of groove enough power, just can finish the program that arch wire entered or shifted out the bracket groove, so that the Principle of Pain degree is higher.And the groove two side also easily under external force impact (for example under the effect at arch wire) expendable distortion occurs, weakened the control of groove for arch wire, rectifying effect is brought adverse effect.Can stressedly relatively move owing to the groove two side simultaneously, thereby have the higher arch wire risk that accident is deviate from from groove.
United States Patent (USP): (publication number is US2011/0059414A1 to orthodontic bracket, priority date: 2008.03.14) disclose a kind of locking bracket, extend to groove bottom from the top, two side of groove (buccal labial surface of locking bracket) have an elastic lamellar latching member, it is the slit of wedge shape that a section is arranged between the sidewall of lamellar latching member and groove.Because the existence of slit, the lamellar latching member is the sidewall generation elastic deformation of groove relatively, it is sheet component deformable under external force, arch wire is pressed into groove by the space between the free end of two sheet components, then sheet component recovers original shape, and its free end can play for the arch wire in the groove maintenance effect as limiting component.Owing to one or two the lamellar latching members of spatial placement between the top, two side that utilizes groove in this patent, and utilize the interior elastic deformation of this lamellar latching member slit scope thereunder to realize the auto-lock function of bracket, therefore the range of activity of this lamellar latching member is very limited, exists large scale arch wire (be such as string diameter 0.021 inch * 0.025 inch arch wire) and be difficult to into problems such as grooves in clinical practice.And since this lamellar latching member in inserting the process of arch wire with respect to the bending distortion of the sidewall of groove, the connecting portion stress concentration of lamellar latching member and groove top side wall, therefore connecting portion is easier to produce permanent deformation or fracture, be that connecting portion is easily bending after strain or fracture repeatedly, make bracket forfeiture auto-lock function and for the control of arch wire.In addition, the arch wire that just abnormal doctor often needs will insert in the groove in the clinical practice takes out, insert again in the bracket groove after readjusting, and this patent reckons without the problem of how easily arch wire to be taken out, cause the complex operation inconvenience of getting silk, and required strength is larger, causes easily the distortion fracture of patient's discomfort and latching member.
