Description
1, technical field
This utility model relates to a kind of apparatus for correcting of malocclusion, specifically a kind of lower jaw the place ahead traction apparatus.
2, technical background
In life, malocclusion is given on patient's the physiology and has all been brought great misery psychologically, they wish can modern medicine can help them to reduce this misery as far as possible, all need use some apparatus for correcting at the correcting process of malocclusion, move to normal position to promote tooth and jawbone.Existing upper jaw the place ahead traction apparatus is only applicable to the rectification of the malocclusion of maxillary retrusion deficiency of development, can't correct the malocclusion of maxillary protrusion, mandibular retrusion, and appliance rectification strength is little in various mouthfuls, promote mandibular bone easily to cause the planar unfavorable rotation of jaw when growing, treatment also might have side effects to make the patient can not get effectively.
3, summary of the invention
The purpose of this utility model is at above weak point, provide a kind of simple in structure, production cost is low, be easy to process, easy to use, can correct mandibular retrusion deformity and the good lower jaw the place ahead traction apparatus of rectification effect.
The technical scheme that its technical problem that solves this utility model adopts is: the upper and lower of L shaped towing bracket be respectively arranged with can relative slip with support volume holder and upper jaw holder, volume holder two ends are respectively arranged with headband, the headband end is provided with junction button; The rear side of upper jaw holder is provided with the upper lip bow; The horizontal component of L shaped towing bracket bottom be provided with can relative slip with it the traction base, the traction base is provided with the traction hook; Inboard at E Tuo is provided with protective lining; On volume holder, upper jaw holder and traction base, be respectively arranged with set screw.
Lower jaw of the present utility model the place ahead traction apparatus is compared with prior art, have reasonable in design, simple in structure, be easy to processing, easy to usely correct characteristics such as mandibular retrusion deformity and rectification effect are good, thereby, have good value for applications.

Accompanying drawing 1 is the front view of lower jaw the place ahead traction apparatus;
Accompanying drawing 2 is the side view of lower jaw the place ahead traction apparatus;
Accompanying drawing 3 is the vertical view of lower jaw the place ahead traction apparatus.
5, the specific embodiment
Explain below with reference to Figure of description lower jaw of the present utility model the place ahead traction apparatus being done.
Lower jaw of the present utility model the place ahead traction apparatus, its structure is by elastic force apron and 2 one-tenth of L shaped towing bracket structures, the upper and lower of L shaped towing bracket 2 be respectively arranged with can with the volume holder 1 and the upper jaw holder 6 of support 2 relative slips, relative distance between volume holder 1 and the upper jaw holder 6 can be regulated, to adapt to different patients; Volume holder 1 two ends are respectively arranged with headband 4, and the headband end is provided with junction button 4; The rear side of upper jaw holder 6 is provided with upper lip bow 9; The horizontal component of L shaped towing bracket 2 bottoms be provided with can relative slip with it traction base 8, traction base 8 is provided with traction hook 7, the front and back position of traction base 8 can be regulated, so that different pull strengths to be provided as required; Be provided with protective lining 10 in the inboard of volume holder 1, make the patient more comfortable in use; On volume holder 1, upper jaw holder 6 and traction base 8, be respectively arranged with set screw 3,, can regulate the relative position between volume holder 1, upper jaw holder 6 and the traction base 8 by regulating set screw 3.
During use, at last mandibular teeth adhere according to a conventional method bracket and band, come into line leveling after, change the stainless steel square silk, terminal inflection, hook is welded at the place in stomach teeth is near; The volume holder 1 of lower jaw the place ahead traction apparatus is fixed on patient's forehead portion by headband 4, adjusting volume holder 1 and upper jaw holder 6 are to the appropriate location, make upper lip bend 9 ends and be able to insert in the molar band buccal tube, and make traction base 8 concordant with the lower jaw hook, parallel to guarantee lead with occlusal surface; Elastic force apron one end is connected on the lower jaw hook, and the traction that the other end is connected on the traction base 8 is linked up with on 7.Upper lip bow 9 is an anchorage, and it forms opposite power with the elastic force apron; Measure traction strength, making lower jaw pull strength when protracting the position is every side 500 grams, and be no less than 10 hours every day pull-in time, also can wear flat bite plate at the upper jaw, helps mandibular protraction and open interlock.Generally through treatment in 4～6 months, maxillary protrusion mandibular retrusion deformity was promptly rectifiable.
Lower jaw of the present utility model the place ahead its processing and fabricating of traction apparatus is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
