Correction moving teeth deviceTechnical field
The utility model relates to a kind of a kind of correction moving teeth of orthodontic tooth device more particularly to dental orthotic dressesIt sets, tooth can be moved in parallel, be free from side effects, for closing or opening interdental gap.
Background technique
Present tooth needs to correct tooth since long is not very neatly arranged.But tooth is corrected nowMaterial rely on helical spring, elastic tape largely to carry out moving teeth, or beat implant anchorage hang screw spring circle tractionCome moving teeth closing gap, especially frist premolar pull out need by Caninemoving distally close extraction of tooth space retract anterior teethWhen, translation canine tooth keeps stable labial teeth position to seem increasingly important simultaneously.But increase patient suffering, rubber due to playing anchorage nailSkin is decayed fastly through strength, and the bad control of helical spring strength and direction is easy to influence adjacent teeth inclination and the laminating covering intensification of labial teeth,There is side effect, along with there are the consumption of frictional force strength to be difficult to control between arch wire and bracket, is unfavorable for the correction to tooth.
Summary of the invention
In order to solve the above-mentioned technical problem the utility model provides a kind of correction moving teeth device and application method, purposeIt is to close or open in parallel interdental gap using elastic yarn.
The utility model correction moving teeth device to achieve the goals above, including elastomer, the one of elastomer bottomFixed body before end connects, fixed body after the other end connection of elastomer bottom, the shape of elastomer is several fonts and Ω wordType.
The front end of the preceding fixed body is equipped with crotch, and rear fixed body is equipped with fixed block.
Preceding fixed body, elastomer and the rear fixed body forms the arc to tooth curving；The preceding fixationThe arc length of body is 7-9mm, and the arc length of rear fixed body is 15-25mm.
The elastomer includes preceding elastomer, curved arc and rear elastomer, and preceding fixed body and the formation of preceding elastomer bend towards toothFirst arc of tooth, rear elastomer and rear fixed body form the second arc for bending towards tooth.
Preceding fixed body, elastomer and the rear fixed body is titanium-nickel wire or nitinol alloy wire.
The bending direction of the crotch and elastomer is towards root of the tooth；Fixed block is cuboid, and fixed block is open at one end
The rear end of preceding fixed body is equipped with the bending segment for bending towards tooth.
The bending segment length is 0.5-3mm.
The application method of correction moving teeth device, it is characterised in that buccal tube and bracket are fixed on are not required to move firstMain arch wire is fixed on buccal tube and bracket by the outside of tooth, and main arch wire is equipped with the second fixed block, mobile not needingBracket on tooth carries out close 8 word ligation；It is needing to be equipped with crotch bracket on the outside of mobile tooth, crotch is hung over into crotch supportOn slot, fixed body after pulling, after opening elastomer, the fixed block on rear fixed body is stuck on the not bracket of moving teeth, thenRear fixed body and main arch wire are fixed with ligature, preceding fixed body and bracket are fixed with ligature.
Further include being inserted in fixed block on rear fixed body, then clamp opening, is fixed on fixed block on rear fixed body；SecondFixed block is stuck on the bracket for first tooth that rear fixed body passes through, and preceding fixed body, elastomer and rear fixed body are located at main bowThe outside of silk.
The utility model has the advantages of: it uses the utility model that can provide superpower anchorage for moving teeth, utilizes nickelThe super-elasticity and Memorability of titanium silk correct the control and soft persistently force that need mobile tooth progress direction, especiallyCaninemoving distally closes extraction of tooth space and provides gap for labial teeth when it is for retract anterior teeth, and when Caninemoving distally will not influenceAdjacent teeth inclination, the laminating intensification of labial teeth and roller-coaster effect.The use of implant anchorage is saved, reduces pain, and valence for patientLattice are cheap, easy to operate, easily and fast, efficiently, strength is soft, tooth direction is easy to control.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Embodiment 1
As shown in figs. 1-7, the utility model correction moving teeth device, including elastomer 3, one end of 3 bottom of elastomerFixed body 1 before connecting, fixed body 2 after the other end connection of 3 bottom of elastomer, the shape of elastomer 3 is several fonts and ΩFont.
The front end of the preceding fixed body 1 is equipped with crotch 4, and rear fixed body 2 is equipped with fixed block 5.
Preceding fixed body 1, elastomer 3 and the rear fixed body 2 forms the arc to 6 curving of tooth.
The elastomer 3 includes preceding elastomer 31, curved arc 32 and rear elastomer 33, preceding fixed body 1 and preceding elastomer 31The first arc for bending towards tooth is formed, rear elastomer 33 and rear fixed body 2 form the second arc for bending towards tooth.
Preceding fixed body 1, elastomer 3 and the rear fixed body 2 is titanium-nickel wire or nitinol alloy wire.
The bending direction of the crotch 4 and elastomer 3 is cuboid towards root of the tooth, fixed block 5, and 5 one end of fixed block is openedMouthful.
The arc length of the preceding fixed body 1 is 7-9mm, and the arc length of rear fixed body 2 is 15-25mm.
Buccal tube 12 and bracket 7 are fixed on are not required to moving teeth 6 first by the application method of correction moving teeth deviceMain arch wire 8 is fixed on buccal tube 12 and bracket 7 by outside, and main arch wire 3 is equipped with the second fixed block 13, not needing to moveTooth 6 on bracket 7 carry out the ligation of close 8 word；It is needing to be equipped with crotch bracket 9 on the outside of mobile tooth, crotch 4 is being hung overOn crotch bracket 9, fixed body 2 after pulling, after opening elastomer 3, the fixed block 5 on rear fixed body 2 is stuck in not moving teethBracket on, then it is with ligature 11 that rear fixed body 2 is fixed with main arch wire 8, preceding fixed body 1 and bracket ligature 11 are consolidatedIt is fixed.
Fixed block 5 is inserted on rear fixed body 2, then clamps opening, is fixed on fixed block 5 on rear fixed body 2；Second is solidDetermine block 13 to be stuck on the bracket 7 for first tooth that rear fixed body 2 passes through, preceding fixed body 1, elastomer 3 and rear fixed body 2 are located atThe outside of main arch wire 8.
Fig. 1 can be used in the orthodontic on the left of lower tooth and on the right side of upper tooth, and Fig. 3 can be used on the right side of lower tooth and on the left of upper toothOrthodontic.
Embodiment 2
The rear end of preceding fixed body in embodiment 1 is equipped with the bending segment for bending towards tooth.Bending segment length is 0.5-3mm.BulletProperty body 3 shape be Ω font.The other the same as in Example 1.
Working principle of the utility model is: main arch wire enter will not need mobile tooth bracket, buccal tube after again with knotTied silk does close Figure of eight bundle and is fixed together, and forms an entirety.Main arch wire, which enters, does not need mobile front teeth bracket simultaneouslyAlso it is pricked to form an entirety with the close Figure of eight of ligature, be fixed on main arch wire.The fixed block 5 on fixed body 2 is stuck in support afterwardsOn slot 7 purpose be prevent the sliding of main silk plus, adjacent teeth inclination is used to reinforce anchorage.Since elastomer is titanium-nickel wire or NitinolSilk has super-elasticity and Memorability.Since spring will restore to the default initial position not opened, after elastomer 3 opens,It bounces back under the action of elastic force, for such crotch 4 also with movement, crotch drives the movement of crotch bracket, and the drive of crotch bracket 9 will moveTooth it is mobile to the direction of retainer 5, since the initial position that spring does not open has been fixed, this is driven to need to move in this wayTooth carried out the locking in final position direction, thus realize constant force, low force, quickly correction.
The fixation of the main arch wire of the utility model is existing fixed form.
