Description
Technical field
The present invention relates to a kind of mouth cavity orthodontic device, and in particular to a kind of bilateral forces down backteeth device, belongs to oral cavity doctor
Treat instrument field.
Background technology
In orthodontic treatments, just needed early stage treatment pair for Class II malocclusion angle of elevation patient and folding patient
Backteeth is carried out vertically to forcing down.There are rear Occlusal pad, Headger, MEAW and micro- implant anchorage etc. in traditional method.For
Closing pad, Headger etc. needs the cooperation of patient, and strength is interruption power, and the bad course for the treatment of of therapeutic effect is longer.MEAW is mainly
The elongation of labial teeth, backteeth it is upright, it is impossible to really realize that grinds one's teeth in sleep forces down.Micro- implant anchorage can be reinforced and imitated in early days
Fruit is notable, but needs to be implanted at least four plantation nail in traditional method, and possible needs re-replace kind during forcing down
Plant the position of nail.It is this that tooth as much as possible is included in the way rescued in system in order to strengthen anchorage, patient can be felt
To inconvenience, the elongation and inclination for causing Anchorage molar are also easy to.The elongation of adjacent teeth can cause the clockwise rotation of lower jaw, before making
Tooth occlusion is opened, chin portion retraction.
The content of the invention
The purpose of the present invention is：
For above-mentioned the deficiencies in the prior art, there is provided a kind of bilateral forces down backteeth device, utilizes the planting body of Palatal suture
As anchorage, the true property of tooth can be forced down, avoid Anchorage molar in the correction method of press-fitting of prior art elongation and inclination and its
The a series of problems brought, while reduce the quantity of planting body, mitigate operation pain and inconvenience for patient.
The purpose of the present invention can be realized by following technical scheme：
Bilateral forces down backteeth device, includes a pair of side brackets bar and the connecting rod between it, is implanted in Palatal suture side by side
Two micro-implants positioned at the root side of first molar, the connecting rod is installed between the rear end of collateral hack lever of bilateral,
Three connectors are respectively provided with the collateral hack lever of bilateral, the front end of the collateral hack lever of bilateral is respectively provided with front haulage hook, the side of bilateral
Be respectively provided with rear towing hook on cradling piece at the second molar, rubber band is hooked between front haulage hook and micro-implant respectively, after lead
Draw between hook and micro-implant.
The connector is shaft-like, upper end is trident.
The front haulage hook is the circular arc of opening upwards.
The rear towing hook is the circular arc of opening upwards.
The beneficial effects of the present invention are：
1st, therapeutic effect is stable：The anchorage imperfect dislocation of teeth problem in the correction method of press-fitting of prior art is avoided, can be by tooth
True property is forced down, and clinically the direction of Orthodontic force and size are also easily controlled.
2nd, have no side effect：The bilateral of the present invention, which forces down backteeth device, to realize upper jaw both sides with reference to the micro-implant of Palatal suture
Backteeth forces down simultaneously, and (conventional method may be during forcing down that will not produce interference to backteeth during forcing down
The Buccoclination of molar intrusion is wanted, and then occurs closing interference), and sagittal can also be carried out to reinforcing improvement mill during forcing down
The II class relations of tooth.Avoid the elongation of Anchorage molar in the correction method of press-fitting of prior art and inclination and its bring a series of
Problem.
3rd, the comfortableness of patient over the course for the treatment of is improved：Reduce the quantity of planting body, while design succinctly, be patient
Mitigate operation pain and inconvenience.
4th, operation risk is low, wound is small：Because Palatal suture two side areas bone density is larger, blood vessel and nerve are less, so
Palate set part is being fixed on Palatal suture both sides using micro- plantation nail, success rate is big, safe, reduces operation simultaneously
Send out disease.Reduce the quantity of planting body compared to conventional method simultaneously so as to reduce operation wound.
5th, manufacture difficulty is low, cost is low, is readily produced and promotes.

Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
The present invention discloses a kind of bilateral and forces down backteeth device, is by the use of the micro-implant of Palatal suture as anchorage, in realization
Jaw both sides backteeth forces down simultaneously, and (conventional method may during forcing down that will not produce interference to backteeth during forcing down
The Buccoclination of molar intrusion can be wanted, and then occurs closing interference), and sagittal can also be carried out to reinforcing during forcing down
Improve the II class relations ground one's teeth in sleep.Avoid the elongation of Anchorage molar in the correction method of press-fitting of prior art and inclination and its bring
A series of problems.The bilateral of the present invention, which forces down the backteeth that backteeth device is connected and can realized, to be forced down, and is opened depending on patient is initial
Depending on conjunction situation, the backteeth that its needs forces down is connected.
The bilateral of the present invention forces down backteeth device, generally use casting cobalt-chromium alloy material.As shown in figure 1, the present invention
Bilateral forces down backteeth device and includes a pair of side brackets bar (1) and the connecting rod (2) between it, the collateral hack lever of the bilateral
(1) at least three connectors (3) are respectively provided with, the front end of collateral hack lever (1) is provided with front haulage hook (4), and front haulage hook (4) is to open
The upward circular arc of mouth.
As shown in figure 1, connecting rod (2) is installed between the rear end of collateral hack lever (1) of bilateral.The connector (3) is
Shaft-like, upper end is trident.
Close be depressed at the adjacent teeth of tooth is respectively provided with rear towing hook (5), rear towing hook on the collateral hack lever (1) of the bilateral
(5) it is the circular arc of opening upwards.
As shown in Fig. 2 during Clinical practice, two micro-implants (6), micro-implant (6) are implanted into side by side in patient's Palatal suture
Positioned at the root side of first molar.Coated with adhesive is bonded to it to be depressed tooth on connector (3) --- i.e. the second premolar teeth
(8), first molar (9), second molar (10).The front end of collateral hack lever (1) corresponds to the position of the second premolar teeth.By oral cavity just
It is abnormal to use rubber band (7), it is hooked in respectively between front haulage hook (4) and micro-implant (6), between rear towing hook (5) and micro-implant (6)
With reinforcing.Rubber band (7) is preferably using chain traction circle.Because micro-implant (6) is located at the root side of first molar, when rubber band (7) place
When extended state acts on rear towing hook (5), tooth that support is connected and then is realized and ground one's teeth in sleep by the strength of a root side
Force down.Rubber band (7) for acting on front haulage hook (4), not only produce a root side tractive force, an also sagittal to
To the strength in remote.Therefore Orthodontic force caused by totality can realize simultaneously backteeth force down and Xiang Yuanzhong movement.
Although the present invention is described and illustrated here by some or some particular arrangements, but its purpose and limit is not lain in
The details is made, because may have various modifications and structure change in the range of patent requirements, without departing from spirit.
The present invention relates to partly same as the prior art or can be realized using prior art.
