Abstract

The utility model discloses a fixture for correction extroversion before tooth abrasion, which is used for preventing the loss of anchorage in the process of correction. A one-arm clasp is connected with the tongue side with a ring, wherein, the one-arm clasp is on the second molar and the second pair of canines, and the tongue side is on the first molar. A bow spring is melted with one end of the multifunctional hook of mouth bow. The hook which looks like a question mark is connected with the multifunctional hook of mouth bow via a ligature. The utility model has the advantages that the ability of supporting tooth extroversion of other ordinary correction appliances is altered, and the movement of molar extroversion is controlled within the lowest limit.

Description

Fixture for correcting extroversion before tooth abrasion

This utility model belongs to the straightening technology of tooth, particularly prevents to grind one's teeth in sleep the mobile technology of rescuing that leans forward.

The method that leans forward of preventing at present to grind one's teeth in sleep includes the effect that utilizes lip flesh, extra-oral anchorage or design ring holder formula activity orthotic device etc., but up to now, do not have a kind of method can control anchorage ideally, leaning forward that prevention is ground one's teeth in sleep is mobile.The control of anchorage is an important topic in just abnormal field.Just abnormal scholars are constantly seeking various methods and are strengthening and protect anchorage.Though removable appliance is extensive use at home still, because its limitation of design, accuracy and the maintenance power of rescuing power are relatively poor, and the appliance that is fixed more and more replaces.Traditional fixedly rescuing usually is made up of band, arch wire, locked groove etc.Band is bonded on the one tooth body, is welded with a common drag hook therewith, if make the horizontally tracting of simple property, then the anchorage tooth is easy to rotate around rersistant center, and even produces to tilt to move, and makes anchorage loss.Arch wire needs often replacing, and the operating technology complexity is difficult for grasping, the main dependence in arch wire source import in addition, and the cost height is applied slower.

The purpose of this utility model will prevent to rescue anchorage loss in the process exactly, and leaning forward that prevention is ground one's teeth in sleep is mobile, and then reaches prevention and lean forward because of grinding one's teeth in sleep due to mobile The purpose that relation is disorderly.

Details are as follows to this utility model below in conjunction with accompanying drawing.Band among Fig. 1 " " type hook (1) is made on the first molar.On second molar and second bicuspid, make one-arm clasp (2) with the stainless steel silk of 0.8mm or 0.9mm, with on one-arm clasp (2) and the first molar "

" type hook (1) tongue side connect in aggregates, then in band (7) cheek side The side makes buccal tube (3), make at an end of buccal tube (3) "

" type hook (1)."

" length of type hook (1) grinding one's teeth in sleep between furcation area and the mucosa turning point.Make a bow spring (9) and a Ti-Ni alloy labial arch multifunctional hook (4) between canine tooth and first molar, an end of labial arch multifunctional hook (4) connects with bow spring (9) weldering."

" type hook (1) is connected by ligation silk (5) with labial arch multifunctional hook (4).Also available in case of necessity elastic tape (6) is drawn.Arch wire (10) is via locked groove (8), bow spring (9), pass buccal surface spring (3) again; Class this, labial teeth links to each other with labial arch multifunctional hook (4) by locked groove (8) and promptly forms one and fixedly rescue single unit system.

Description of drawings:

Fig. 1 rescues the fixture sketch map that leans forward mobile of grinding one's teeth in sleep.

Fig. 2 be " " the whole band sketch map of type hook.

Fig. 3 bends terminal sketch map for multi-functional lip.

Below for a kind of general see rescue example

Between the putting in order of tooth can be regarded as therefrom two front teeth push away to the left and right sides respectively number as

In case, there is an example to be

Prolapse need be pulled out

, interior receipts , at this state of an illness should with labial arch multifunctional hook (4) with "

" rustless steel ligation silk (5) connection of type hook (1) end, take 5/16 cun elastic tape (6) traction

Xiang Yuanzhong moves, and apron (6) one ends connect labial arch multifunctional hook (4), and the other end connects

In far away.Canine tooth with

After drawing close, will On the band (7) "

" type hook (1) ligation silk (5) connection. With elastic tape (6) traction,

Xiang Yuanzhong moves.After labial teeth evenly scatters, reuse elastic tape (6) connection "

" the terminal and labial arch multifunctional hook (4) of type hook (1).Because the elastic force effect of apron (6), traction labial arch multifunctional hook (4) Xiang Yuanzhong slides, space closure, The interior receipts, the prolapse deformity is promptly corrected.

This utility model is by using, and its superiority is embodied in except that trailed tooth, and all teeth all play the anchorage effect in the dental arch.In addition, by to the utilization of anchorage mutually in the jaw, just abnormal tooth is moved simultaneously in far away.The strength major part that anchorage is moved is repealed by implication, and part is dispersed on each anchorage tooth.When a side grinding tooth application of force, its reaction force acts can be offseted the strength that counteracting force moves forward on offside is ground one's teeth in sleep.Because " " application point of power of type hook is positioned at the impedance center or slightly in its root side, thereby changed the conventional appliance anchorage tooth mobile movement tendency that leans forward.Because of making 5,6,7 teeth be linked to be an integral body that is become many districts, one-arm clasp grinds one's teeth in sleep again.So strengthened the ability that opposing tilts to move.Action time of this device is short, is anchorage to grind one's teeth in sleep just in the final stage of rescuing only, and can make grinds one's teeth in sleep leans forward to move and be controlled at bottom line.Its multi-functional lip bow does not need frequent change, and cost is low, is convenient to promote.
