Description
Technical field
This utility model relates in a kind of dental orthodontic for the adnexa of bracket, be specifically related to a kind of between Orthodontic Treatment Tooth jaw, the plucked formula bracket hook of intramaxillary traction.
Background technology
When being mainly used in department of stomatology denture correction, hook hangs elastic thread or elastic tape draws use.At clinic orthodontic, rescue in process, between jaw and intramaxillary traction be one of the most frequently used method.Effectively implement between jaw and the prerequisite of intramaxillary traction is the making of hook and lays.
Present stage, in clinical middle hook kind, have and on arch wire, weld hook (operation exception trouble, cost is high), bracket fixed traction hook (cost of manufacture increase, may stimulate oral mucosa while not drawing) and the homemade bracket hook of ligature (undercapacity, controlled poor).With hook on arch wire, draw, be conducive to whole dental arch integrated moving, but lack the motility that indivedual teeth are regulated.While drawing with bracket hook, can to indivedual or minority tooth carry out sagittal to, vertically to movement, be conducive to rescue the control to tooth three-dimensional in process.
In prior art, bracket hook has the homemade bracket hook of ligature, and is directly attached to the bracket hook on the bracket wing.But these two kinds of bracket hooks have deficiency, bracket hook undercapacity as homemade in ligature can deform due to the impact of pull strength in clinical practice; Although the bracket hook being directly attached on the bracket wing has enough intensity to implement traction, motility is not enough, and its fixed traction hook comfort level is not good enough, can not extract as required and convert the position of hook; Classification is simultaneously offered relevant bracket mould and is also expended huge.
Utility model content
This utility model is intended to provide a kind of formula bracket hook of plucking, and to solve, existingly fixedly rescues in technology bracket hook position adjustment difficulty and extracts inconvenient problem.
Plucked formula bracket hook in this programme, is characterized in that: comprise for the retention arm around consolidating on bracket, retention arm comprises and can, for the hook arm of traction, be connected with the dislocation ring of dislocation use at described hook arm end.

The feature of technique scheme comprises:
1. can pluck formula bracket hook make simple, can to indivedual or minority tooth carry out sagittal to vertical to movement, be conducive to rescue the control to tooth three-dimensional in process, rescuing the change of power system is its main feature.
2. can pluck formula bracket hook and can extract easily after the traction stage finishes, be conducive to improve patient's comfort level, can be used as a kind of new adnexa of bracket and use.
3. can pluck formula bracket hook and also possess the advantage that preparation cost is cheap, only need a mold can meet the demand of production, without bracket, divide attached hook and two types of making of not attached hook, cost-saving, being also beneficial to the oral mucosa reducing under traction state not stimulates.
4. can pluck formula bracket hook has enough intensity, not deformed by influence of tractive force, in the mode of simplifying most, assists a physician and carries out clinical treatment, increases work efficiency.
5. can pluck formula bracket pintle hook construction simply without dead angle, be easy to reach the harsh health demand of medical apparatus and instruments.
6. can pluck formula bracket pintle hook construction flexible, can be around solid on heteroid bracket, adaptability is stronger.
As optimal way, described retention arm comprises that the tooth connecting successively closes arm, upright arm and gum arm, and described tooth closes arm and is positioned at the bracket tooth side of closing, its free-end is crooked to bracket side, described upright arm is positioned at bracket side, and described gum arm is positioned at bracket gum side, and gum arm is connected with hook arm.
" tooth closes " that described tooth closes in arm should be a word, and the left avertence side of this Chinese character is " tooth ", and right avertence is other is " closing ".It is a word conventional in stomatology, represents the meaning of interlock, because of computer input method, cannot input therefore presented by two word combinations.
Originally can pluck formula bracket hook can use as required on the bracket at the upper jaw or any position of lower jaw, position that can flexible transformation hook.Can need to select the position of upright arm according to traction, can be on bracket left side or right side.For clinical manipulation person provides a kind of, carry out in multiple jaw flexibly, easily and the method for intermaxillary traction.
As optimal way, described tooth closes arm free-end to bracket lateral bend, crooked form can also be adjusted according to actual situation, prevent that it from protrudingly causing damage to mucosa, the pessimal stimulation of minimizing to human oral cavity mucosa, the dislocation ring of described dislocation use is positioned at hook arm free-end simultaneously, is convenient to dislocate in clinical manipulation, can prevent that this bracket hook end is to the stimulation of oral mucosa or damage simultaneously.
As optimal way, originally can pluck formula bracket hook and select 0.5mm stainless steel silk, 0.018 inch of Australia's silk or other corrections to make of arch wire.
Whether accurately the application also provides a kind of plucked formula bracket hook of capable of dynamic data feedback simultaneously, and it is intended to except above-mentioned technical problem, can also solve doctor in prior art and be difficult to immediately estimate correction traction dynamics problem.
This programme is that the scheme based on above-mentioned improves, further, on hook arm, be provided with strain gauge, it is spiral type that tooth closes arm free-end, the latter end recurvation of free-end is placed in described spiral type, and clamping in spiral type have a wireless launcher being electrically connected to strain gauge.
The feature of technique scheme is: the components of stress scattergram that it can be created in correction traction process, allows dentist collect more accurate traction stresses data, for treatment or other work afterwards provides abundanter information." the latter end recurvation of free-end is placed in described spiral type " can better guarantee the process of installing or using, and the sharp parts that can avoid tooth to close the free latter end of arm from all angles causes damage to human body.By described spiral type, also provide the space that can settle wireless launcher simultaneously, the signal of strain gauge output can have been sent to extraneous receiving system.
This utility model also provides a kind of hitch structure of plucking formula bracket hook, to solve the above-mentioned placement issue of formula bracket hook in oral cavity of plucking, provides the correction that can specifically implement traction protocols.
The hitch structure that can pluck formula bracket hook has been used the plucked formula bracket hook in technique scheme, comprises the bracket being attached on tooth, can pluck formula bracket hook around admittedly on bracket, and draught line is connected to hook arm or tooth closes on arm.By described structure, can form a complete correction system, realization can be plucked the concrete application of formula bracket hook.
