One kind is ground one's teeth in sleep and is oriented far middle mobile orthotic deviceTechnical field
This utility model is related to Buccodental orthotic device technical field, rescues dress particularly to one kind displacement of grinding one's teeth in sleepPut.
Background technology
In clinical children and youth case, often occur and lead to maxillary first molars early stage to lack because of severe dental caries,And second permanent molar does not reach eruption time.Now, clinically need far middle for two premolarss movement to occupy the first millThe gap of anodontia, had so both prevented the mesioversion eruption of second molar to occupy first molar gap, and can release labial teeth againCrowded, be to have tooth pulled out less during second stage orthodontic treatment or non-extraction treatments makees early-stage preparations.
During the in the past clinical problems in solution, generally there is following several way: the first is by grinding before pulling out firstTooth is releasing, but excessive Patients are displeased；Second is to grind before far middle implantation plantation nail to draw two as Enhanced anchoraseThe far middle movement of tooth opens up gap for incisor, and this method depends on the position of plantation nail and the accurate displacement of lead, toothIt is difficult to realize, also there is the possibility that implant anchorage gets loose；The third method, also with the implant anchorage being fixed on palatine, will be prolongedStretch the Boards wall in far middle alveolar bone and be welded with hook on the anchorage train wheel bridge of palatine, be moved back by for drawing premolarssDynamic, equally there is also implant anchorage or clamping plate rides for a fall the problems such as loosening.
Utility model content
Technical problem to be solved in the utility model be provide a kind of move accurately, rectifying effect is good, be easy to operateThe far middle mobile orthotic device of orientation of grinding one's teeth in sleep.
By solving the technical scheme that above-mentioned technical problem is adopted: one kind is ground one's teeth in sleep and oriented far middle mobile orthotic device, includingMaintenance unit, it includes the first conjuncted band being located therein in the denture of side and in other side denture second conjunctedBand, the lip side of described second conjuncted band and tongue side are correspondingly provided with lip side band cheek pipe and tongue side band cheek pipe respectively；AnchorageUnit, it includes the base fitted with Hubei Province film；And displacement unit, it includes connect fixing with the first conjuncted band and baseThe support connecing, is respectively equipped with and the lip side band cheek pipe on the second conjuncted band and tongue side band positioned at far middle place on the bracketThe corresponding lip side cheek pipe of ring cheek pipe and tongue side cheek pipe, tongue side band on the tongue side cheek pipe on described support and the second conjuncted bandExtend through between lip side cheek pipe between cheek pipe and on support and the second conjuncted band upper lip side band cheek pipe and be formed with twoArch wire is to form two line slideways, so that described second conjuncted band moves along line slideway direction under external force.
Further, described first conjuncted band is correspondingly arranged on two premolarss and a sixth-year molar by threeBand forms, and described second conjuncted band is made up of two bands being correspondingly arranged on two premolarss.
Further, it is provided with inserted link on the bracket, be provided with inserting for support in the tongue side of the described first conjuncted bandThe jack that bar insertion connects.
Further, it is provided with a suspension hook between the lip side cheek pipe of described support and tongue side cheek pipe.
Further, it is provided with recess positioned at closely middle place on the bracket.
Further, described arch wire is square silk.
Beneficial effect: this grinds one's teeth in sleep in the far middle mobile orthotic device of orientation, and the second conjuncted band is fixed on two premolarss,By making line slideway direction accurate movement that the second conjuncted band constitutes along two arch wires in the presence of external force so that twoPremolarss accurate movement occupies the gap of first Molar.Before this utility model abandoning tradition is using plantation nail tethered slidingThe mode ground one's teeth in sleep, is used as stress point come the conjuncted band of tethered sliding second by the first conjuncted band, base, simple to operate justVictory, it is minimum that what early stage produced during rescuing rescue error, can greatly improve rectifying effect.

Specific embodiment
Referring to figs. 1 to Fig. 4, this utility model one kind is ground one's teeth in sleep and is oriented far middle mobile orthotic device, including maintenance unit, its bagInclude the conjuncted band of first being located therein in the denture of side 11 and the in other side denture second conjuncted band 12, secondThe lip side of conjuncted band 12 and tongue side are correspondingly provided with lip side band cheek pipe 13 and tongue side band cheek pipe 14 respectively；Anchorage unit, itsIncluding the base 21 fitted with Hubei Province film；And displacement unit, it includes connect fixing with the first conjuncted band 11 and base 21The support 31 connecing, is respectively equipped with and the lip side band cheek pipe 13 on the second conjuncted band 12 and tongue positioned at far middle place on support 31The corresponding lip side cheek pipe 32 of side band cheek pipe 14 and tongue side cheek pipe 33, the tongue side cheek pipe 33 on support 31 and the second conjuncted bandLip side cheek pipe 32 between tongue side band cheek pipe 14 and on support 31 and the second conjuncted band 12 upper lip side band cheek pipe 13 on 12Between extend through and be formed with two arch wires 34 to form two line slideways, so that described second conjuncted band 12 is in external forceEffect lower edge line slideway direction is moved.
In the present embodiment, the first conjuncted band 11 is arranged in the denture not needing to rescue, and is correspondingly arranged two by threeBand composition on premolarss and a sixth-year molar, each band is sequentially connected formation conjuncted structure and effectively improves retainerDivide intensity；Second conjuncted band 12 is then arranged in the denture needing to rescue, by two bands being correspondingly arranged on two premolarssRing group becomes, and it is also conjuncted structure.
Support 31 is hanging supporting structure, and support 31 1 side is extended to and is connected with the first conjuncted band 11, specificallyGround, a side of this support 31 is formed with least one inserted link 35, is provided with least one confession in the tongue side of the first conjuncted band 11The jack 15 of inserted link 35 insertion, inserted link 35 and jack 15 junction carry out soldering, thus by support 31 and the first conjuncted bandRing 11 is fixing to form one, and the first conjuncted band 11 and support 31 can mitigate the difficulty of 3d printing, have using split-type designEffect ground improve production efficiency.
Support 31 other side end extends the ring-type constituting around the second conjuncted band 12, and two arch wires 34 are each passed through tongueSide band cheek pipe 14 and tongue side cheek pipe 33 and lip side band cheek pipe 13 and lip side cheek pipe 32, two arch wires 34 spacing guiding andSo that the far middle shifting of line slideway direction accurate pointing that constitutes along two arch wires 34 of the second conjuncted band 12 in the presence of external forceDynamic, so that two premolarss accurate movements occupy the gap of first Molar.Wherein, arch wire 34 is preferably stainless steel squareSilk.
Preferably, being provided with a suspension hook 36, the position of this suspension hook 36 between the lip side cheek pipe 32 of support 31 and tongue side cheek pipe 33Put above just at unerupted second permanent molar, suspend unerupted second permanent molar in midair such that it is able to convenient.Additionally, propping upIt is provided with recess 37 positioned at closely middle place, this recess 37 can play the effect of traction adjustment canine tooth crowding it is also possible to rise on frame 31To the effect for fixed support 31.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited toState embodiment, in the ken that described technical field those of ordinary skill possesses, can also be without departing from this practicalityOn the premise of new objective, various changes can be made.
