Description
Technical field
The invention belongs to mouth cavity orthodontic instrument field, in particular to led outside a kind of correction mouth that can be used for transparent appliance
Leading-in device.
Background technique
Transparent appliance is the transparent resilient plastic removable orthodontic appliance device by computer-aided design and manufacture, it is by a system
The orthotic device of column reaches correction mistake by the moving teeth that constantly reduces the scopeThe purpose of deformity.Compared to traditional fixation
Appliance, transparent correction apparatus have the advantage that (1) beauty, and appliance is colourless transparent material, is particularly suitable for adult patients
With certain patients for having psychological burden and special occupation patient；(2) hygienic, patient can voluntarily replace appliance, and oral hygiene is easy
Cleaning；(3) comfortably, appliance is close to tooth and tooth is consistent form, does not stimulate oral cavity hard and soft tissue, and patient's mouthfeel is relaxed
Suitable, the operating time is short by (4) chair, further consultation interval time length etc..For certain correction cases, need to cooperate when using fixed appliance
External traction device is drawn to obtain optimum efficiency；However, not having still at present if this kind of patient selects transparent appliance
For the external traction device of transparent appliance, curative effect is affected.The mode that transparent appliance provides external anchorage at present only has
Mouth is implanted into anchorage nail, however anchorage nail implantation is invasive surgical, and price is relatively high, and not all patient can receive；
In addition, some patientss, especially teenager, because sclerotin is softer, anchorage nail is easy to loosen, and can not apply.It would therefore be highly desirable to develop one
Kind is used for the correction external traction device of transparent appliance.
Summary of the invention
It is led outside a kind of correction mouth for transparent appliance in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide
Leading-in device, the device force down movement using transparent appliance progress orthodontic process Tooth especially suitable for patient.
Present inventive concept: designing protrusion on transparent appliance and cooperates external traction device, helps tooth using mouth external force
Tooth is mobile, is particularly suitable for helping tooth to force down movement when patient is rescued using transparent appliance.
Correction external traction device provided by the invention is formed by drawing prominent, draft arm, elastic component and head cap.It is described to lead
Draw dash forward for the transparent integrally formed protrusion of appliance ontology, setting force application part, the other end and head are needed on transparent appliance
What is be arranged on cap has the connection of certain tensile deformation ability elastic component, and the head cap is by enclosing the matched loop fabric of size with the number of people
Band and in decussation, both ends be separately fixed at two strip fabrics bands on round cloth band constitute (sagittal to, it is coronal to and water
The strap composition to three is put down, head can be wrapped, stable support is provided), two webbings of intersection are in and number of people top radian phase
The arch matched, it is whole in the hat shape that can wrap head.
Further, elastic component setting corresponds to above human ear on head cap, by spring, offers the safety of aperture
Valve, the hole bit slice composition for being provided with multiple through-holes being arranged in a linear.The safety valve is the cylindrical housings for offering aperture,
The spring one end is fixed on safety valve inner wall, and preferably the corresponding bottom hole of aperture, the other end are fixedly connected with hole bit slice, even
One end that the place of connecing hole bit slice is connect with spring is provided with the positive stop strip that width is greater than safety valve opening diameter, the setting limit of hole bit slice
One end of item and spring are respectively positioned on safety valve enclosure interior, and hole bit slice stretches out safety valve different length under different pulling force, until
Positive stop strip is stuck in aperture, so that limited spring excessive tensile generates excessive and fails that (spring reaches maximum tension length at this time, example
As that maximum pull can will be allowed to be set as 300g as needed).The draw hook end is securable to different hole locations, to utilize bullet
Property part different stretch degree, pass through traction wall and apply different size of tractive force.
Further, the integrally formed traction protruding head portion opposing root of the transparent appliance expands (in drops), institute
It states draft arm and the prominent one end connected of traction is arranged to and draws the prominent matched annular shape of size, traction, which dashes forward to be inserted in annulus and realize, to be connected
It connects.Draft arm can be bent by the stainless steel wire of diameter 1.0mm or so, and end circular loop internal diameter is maximum slightly larger than traction protruding head portion
Outer diameter, draw hook are inserted in annulus realization and are detachably connected, facilitate patient voluntarily to pluck and wear.
Further, because tractive force direction is generally upward, Xiang Yuanzhong, therefore the draw hook generally answers downward, Xiang Jinzhong,
It prevents from slipping.Further, the traction is prominent can be set between maxillary central incisors and lateral incisor, each setting one of bilateral symmetry
It is a.
Further, the draft arm is arc-shaped at bicker, avoids bicker.
Further, the webbing is medical strap or medical nylon tape.
In above scheme, protruding head portion maximum diameter generally about 6mm, root narrow place diameter generally about 3-4mm are drawn, it is long
Spend general about 3-4mm.
The application method of correction external traction device provided by the invention: when patient needs by receiving, force down in mouth external force
When Upper Anterior Teeth, the traction device is used；Traction integrally formed to the position in requisition for force is prominent on transparent appliance, will draw
The traction of arm annulus end cap transparent appliance in mouth is prominent upper (such as Fig. 3), and it is suitable that the other end passes through head cap elastic component hole location on piece
Through-hole connect with head cap, carry out low force traction.Head is as the overall active force by opposite direction of anchorage.Positive stop strip limitation
On the one hand spring maximum tension length to limit spring maximum pull protects tooth will not be by great
Injury, on the other hand also prevents the damage of transparent appliance.
Compared with prior art, the invention has the following advantages:
1, the traction device can for transparent appliance it is more flexible and convenient the tractive force in required direction is provided, be not required to invade
The operation of entering property, material cost is relatively low, and patient is acceptant, and the patient that cannot be in particular implanted into anchorage nail provides another kind
Solution.
2, different from conventional metals fixed appliance, transparent appliance is plastics, cannot bear excessive power；For this purpose, this
It invents specially designed positive stop strip and limits spring maximum tension length, to limit spring maximum pull, it is therefore prevented that because applying
The transparent appliance of the excessive damage of power or injury human body.
3, traction device structure of the present invention is simple, easy to use, and traction effect is good.
