Specific embodiment
With reference to Fig. 1-4, present invention is described.
As shown in figure 4, first molar 1, second molar 2 are respectively positioned on the homonymy of lower jaw, and impacted wisdom tooth 3 with impacted wisdom tooth 3
It is adjacent with inferior alveolar nerve pipe tight.Herein homonymy refers to left side or right side.
Impacted Mandibular Wisdom traction apparatuss, including for be seated in first molar 1, the support 5 of the tongue side of second molar 2, use
In be seated in the first retention feature 6 of the side of being preced with of impacted wisdom tooth 3, the second retention feature for being seated in the cheek side of first molar 1, two
The traction element that end is connected respectively with the retention feature 6 of support 5 and first.Support 5 includes shape body 54, union joint 51, connection
Bar and cross bar 52, shape body to be corresponded to and be respectively equipped with union joint 51, the correspondence of shape body 54 at first molar 1, second molar 2
It is provided with groove 53 and cross bar 52 at impacted wisdom tooth 3, cross bar 52 is parallel with shape body 54 and positioned at the tooth conjunction side of shape body 54,
Cross bar 52 is connected by connecting rod with shape body 54.Using traction element connecting bracket and the first retention feature, can be flexible
The direction of traction impacted wisdom tooth is adjusted, therefore can effectively draw separation impacted wisdom tooth and alveolar nerve pipe within a short period of time,
Avoid direct extraction of wisdom tooth from damaging inferior alveolar nerve and cause numbness of lower lip, to facilitate follow-up exodontia treatment.Groove can aid in becoming
Change the position for adding force.Because the present invention can flexibly change force direction, therefore the indication treated is wider.Second maintenance
Part is seated in the cheek side of mandibular first molar 1, can effectively prevent during traction impacted wisdom tooth, and first, second grinds one's teeth in sleep
It is mobile in remote.
If impacted wisdom tooth is located closer to bite plane, the first retention feature selects lingual button.Lingual button bonding
In the distal surface of impacted wisdom tooth corona.
If impacted wisdom tooth is near root side, the first retention feature is made up of stainless steel 62 and stainless steel ring 61, rustless steel
The two ends of bar 62 are connected to a stainless steel ring 61.First retention feature can be curved with the stainless steel silk of a diameter of 0.6mm
System.Impacted wisdom tooth near root side when, first will parcel impacted wisdom tooth gingiva tissue strip off, by a rustless steel of the first retention feature

And be bonded in 52 on the cross bar of support by fluid resin.Using the traction element of the structure, can pass through to adjust buccal tube
Direction adds force direction to adjust, and so can simultaneously produce strength vertically upward, and allows wisdom teeth to be located in titanium-nickel wire
Plane on rotated.The plane that wherein titanium-nickel wire is located is according to designed by the tip of a root of wisdom teeth and the position relationship of neurocele
Out.
Second retention feature includes grind one's teeth in sleep retainer 8 and the micro- implant anchorage nail 7 for being seated in 1 side of first molar,
Retainer 8 of grinding one's teeth in sleep includes a connecting rod 83, and one end of connecting rod 83 is provided with and is adapted with the cheek side outer contour shape of first molar 1
Union joint 81, the other end is bent to form ring-type, and the annular termination 82 of retainer of grinding one's teeth in sleep is placed on the head of micro- implant anchorage nail 7,
And be stably connected with the two with fluid resin.Annular termination can be with jagged.
The union joint of support is adapted with the first molar, second molar tongue side face outer contour shape.
Union joint is preferably claw-like.
With reference to Fig. 4-7, the application of impacted wisdom tooth traction apparatuss of the present invention is illustrated.
The clinical symptoms of patient：Impacted wisdom tooth is mesioangular impaction, and close bite plane, as shown in Figure 5.
Traction method of the present invention：Support is positioned over into impacted wisdom tooth tongue side, union joint is adhered to into first, second and is ground one's teeth in sleep
Tongue side face.Lingual button is adhered to into impacted wisdom tooth exposed hat side.By micro- implant anchorage nail implantation first molar buccal root side,
The annular termination of retention feature of grinding one's teeth in sleep is fixed on into the head of anchorage nail, union joint is adhered to first molar buccal aspect.By buccal surface
Pipe is adhered on cross bar, and buccal tube, perpendicular to bite plane, one end of titanium-nickel wire passes through the other end of buccal tube, titanium-nickel wire to consolidate
It is scheduled on lingual button.Using said method, can simultaneously to vertical and remote middle tongue to traction impacted wisdom tooth, the pull-in time is 3---6
Individual month, impacted wisdom tooth can be separated with inferior alveolar nerve pipe, as shown in Figure 6.Hereafter, impacted wisdom tooth can be pulled out.
Therapeutic process of the prior art：
