Abstract
The present invention relates to an oral cavity orthodontia function appliance, it is formed from upper denture base and lower denture base, the middle of the upper denture base is palatal bar, two ends of palatal bar have maxillary complete crown, upper occlusal pad and fixing wing, and the middle of the lower denture base is lingual bar, two ends of lingual bar have mandibular complete crown and lower occlusal pad. Said invention adopts one-step integrated casting technique.
Description
Technical field the present invention relates to a kind of mouth cavity orthodontic activator.
Background technology is in the mouth cavity orthodontic field, and activator is an important kind of appliance, and it can be divided into fixed and movable two kinds again.The fixed function appliance comprises the Herbst appliance, interlock leaping organ etc.; Active activator comprises bionator, activator, movable two pad appliances etc.
In the movable function appliance, be representative with movable two pad appliances.Movable two pad appliance, constitute by hook, pad, lip bow, division spring and adnexa upper lip bow, division spring, face-bow etc. between improvement arrow card, triangle card, bulb portion and (to see " the modern orthodontics diagnosis and treatment handbook that Ceng Xianglong edits, publishing house of Beijing Medical University, in July, 2000 version, P180-181), it is with low cost, rectifying effect is better, do not influence interlock, but volume is bigger, and pronunciation is under some influence, and must rely on the patient to cooperate.
In general, if can use the fixed function appliance, just as far as possible need not be active, because can being got voluntarily by the patient, the latter wears, need the cooperation of dependent patient, so effect is relatively poor relatively.In the fixed function appliance, be representative with the Herbst appliance.The Herbst appliance partly is made up of mechanical part and anchorage.Mechanical part is made up of sleeve pipe, inserted link, screw and axle bed, and anchorage partly is the band of first molar and first bicuspid up and down.During use, inserted link is inserted in the sleeve pipe, oily fixed screw is twisted inserted link and telescopic screw axis hole admittedly on axle bed, and axle bed is welded in the band side.It is higher that it rescues efficient, but because backteeth does not have the interlock contact, patient's masticatory function is limited.Also there is following problem in this appliance in addition: 1, complex manufacturing technology, and parts are more, cost is high; 2, in the therapeutic process, device damages easily, easily comes off even ruptures as weld sealing-off, band; 3, anchorage control is not satisfactory, causes drifting tooth; 4, be difficult for wearing usefulness for tooth phase patient.After have the people that it has been done improvement, design the Herbst appliance of plastic splint anchorage, but the volume of plastic splint is bigger, not as band formula anchorage comfortable, need the patient to cooperate, be not easy to use simultaneously fixed appliance.Also have the scholar to propose casting clamping plate type Herbst appliance, it has overcome the deficiency (seeing the P178-179 that submits a written statement to a higher authority) of above-mentioned design.But because the construction features of Herbst appliance itself, device still damages easily, and in clinical practice, the casting clamping plate are difficult to take off from tooth.
Summary of the invention the objective of the invention is according to above-mentioned present situation, aim to provide the advantage of a kind of two pad appliances of energy absorption activity and casting Herbst appliance, determined curative effect, do not rely on the patient to cooperate, can be used fixed appliance simultaneously, processing technology is simple, the fixing two pad appliances of casting with low cost.
The implementation of purpose of the present invention is that the fixing two pad appliances of casting are made of upper and lower dens supporter.In the middle of the last dens supporter is palate bar 2, and there is upper jaw complete crown 4 at palate bar two ends, goes up the pad 5 and the maintenance wing 7.In the middle of the following dens supporter is tongue bar 1, and there are lower jaw complete crown 6, following pad 3 in tongue bar two ends.
The present invention is made of upper and lower dens supporter, upper and lower dens supporter with in molten or acolite make.The palate bar 2 that upper jaw complete crown 4 about last dens supporter, last pad 5 usefulness are close to palatine mucosa connects, upper jaw complete crown 4 is positioned on the maxillary first molar, to the mandibular first molar place, be advisable to cover mandibular first molar face by the size of last pad 5 in both sides upper jaw backteeth Founder for last pad 5.Other also can increase complete crown on backteeth of eruption or the still firm deciduous molar fully, to strengthen maintenance.Also have the maintenance wing 7 in the place ahead of upper jaw complete crown 4, the maintenance wing 7 is positioned at the tongue side of upper jaw second bicuspid or second deciduous molar, works to strengthen maintenance.Can empty going up pad 5 for weight reduction, thick about 1.5 millimeters of face is born main interlock function.Upper jaw complete crown 4 thick about 1.5mm.
The lower jaw complete crown 6 of the following dens supporter left and right sides is positioned on the mandibular first molar, and following pad 3 usefulness tongue bars 1 connect, and tongue bar 1 is close to the lingual surface of each tooth, and the vertical and lip cheek that does not hinder tooth simultaneously is to moving.Be close in pad 5 near and cast pad 3, contact surface makes lower jaw be in protrusive position to 75 ° of mesial inclinations.The cause effect of pad down is to stop the lower jaw retraction, do not bear masticatory function, so volume can dwindle as far as possible.
If need gradation reach lower jaw, can be with descending each the face casting of pad crude, so that add self curing plastic.
This appliance is except the indication that is suitable for two conventional class patient function corrections, to there being the uneven mandibular retrusion patient of crowded dentition suitable equally.
The present invention is simple in structure, in light weight, cost is low, easy to operate, the suitability is strong.
The present invention has following advantage:
1, keeps the advantage of movable pair of jaw pad appliance, do not influenced interlock;
2, adopt the Integratively foundry engieering, work simplification does not need to buy part, and there is not the problem of sealing-off, fracture in the intensity height;
3, volume-diminished has reduced patient's sense of discomfort;
4, absorbed the advantage of casting Herbst appliance, promptly determined curative effect can adopt fixed appliance, the efficient height simultaneously;
5, adopt fixture, the patient can not get voluntarily and wear;
6, cost is low.

Specific embodiment the present invention is made of upper and lower dens supporter, upper and lower dens supporter with in molten or acolite make.The palate bar 2 that upper jaw complete crown 4 about last dens supporter, last pad 5 usefulness are close to palatine mucosa connects, the lower jaw complete crown 6 of the following dens supporter left and right sides, pad 3 usefulness tongue bars 1 connection down.Thick about 1.5 millimeters of pad 5 faces, upper jaw complete crown 4 thick about 1.5mm.The contact surface of following pad 3 and last pad 5 is to 75 ° of mesial inclinations.
