Description
Technical field
The present invention relates to orthodontic engineering device technique fields more particularly to a kind of bone anchorage to expand bow device and its application method.
Background technique
Orthodontic occupies critical positions in modern medicine.Wherein, for upper mandibular dental arch bilateral or unilateral constriction
Etc. such situation, principle is rescued, is that expansion screw is placed on suitable position, opens big expansion bow by rotating threaded hole
Device, and reason will be rescued and passed to by sustenance to tooth and alveolar bone, to expand the width and length of upper mandibular dental arch.
Expansion screw in the prior art, after fixed installation, need to pass through by small tool daily intermediate through-hole into
Row expands bow, and tolerance is poor, and use intensity is weaker, and therefore, there are rooms for improvement for the prior art.
Summary of the invention
Place in view of above-mentioned deficiencies of the prior art expands bow device the purpose of the present invention is to provide a kind of bone anchorage and its makes
With method, it is intended to which use intensity is poor in the prior art for solution, the short problem of service life.
In order to achieve the above object, this invention takes following technical schemes:
A kind of bone anchorage expansion bow device, comprising:
First tractive unit, first tractive unit include the first sliding block and extended outward to form by the first sliding block one group
First support；
Second tractive unit, second tractive unit include the second sliding block and extended outward to form by the second sliding block one group
Second support；
First guide post and the second guide post, first guide post is connect with first sliding block and the second sliding block respectively, described
Second guide post is also connect with first sliding block and the second sliding block respectively, and first guide post and the second guide post are symmetrically disposed on institute
State the two sides of first support and second support；
It is connect at axis, described axis one end and the center of first sliding block, in the other end and second sliding block
It is connected at the heart, one end of the axis is provided with and substantially adjusts bolt end, and the other end, which is provided with, slightly adjusts bolt end；
Master slider, integrally formed with master slider at the center of the axis, the master slider between first sliding block and
Between second sliding block；
Spanner, the bone anchorage expand bow device and are configured with spanner, and the spanner is for adjusting the first tractive unit and the second traction
Gap between portion.
Optionally, it is threadedly engaged respectively between the axis and first sliding block and the second sliding block.
Optionally, the cross section of the master slider is regular polygon, and the diameter of the master slider is greater than the axis
The diameter at both ends.
Optionally, the spanner includes large size spanner and small size spanner, 34 centimeters of the large size key length, small size spanner
28 centimeters.
Optionally, the bone anchorage expands application of the bow device on the tractor in maxilla mouth.
Optionally, first sliding block and the second sliding block are respectively arranged with 2 mounting holes.
Optionally, be provided with the first spacing shim between first sliding block and the master slider, second sliding block with
The second spacing shim is provided between the master slider.
In order to achieve the above object, this invention takes following technical schemes:
A kind of bone anchorage expands the application method of bow device, comprising the following steps:
The first step assists precise positioning correction position by Maxillary region pyramidal tract CT, selects bone thickness enough
Region；
Second step, it is spare using upper jaw modelling personalization band or casting crown；
Third step, bend first support and second support make bone anchorage expand bow device and band or casting crown connect into one it is whole
Body, it is spare；
4th step makes bone anchorage expand bow device and connects into an entirety with band or casting crown using silver soldering connection technology, spare；
Then bone anchorage is expanded bow device using plantation nail and is fixed on sufferer by the 5th step, polishing, polishing, autoclave sterilization
Palate on such as the place that is positioned in the first step；
6th step corrects process according to sufferer, collocation improvement time, number and using spanner to substantially adjusting bolt end
Or slightly adjust the adjusting of bolt end；
7th step, after reaching desired effects, excision.
Optionally, the spanner that the bone anchorage expands bow device may be respectively used in adjustment and substantially adjust bolt end, slightly adjust spiral shell
The rotation of bolt end or master slider, to adjust the gap between the first sliding block and the second sliding block.
Optionally, it is to the adjusting for substantially adjusting bolt end or small size adjusting bolt end using spanner in the 6th step
It is unidirectional to adjust.
Present invention can apply to the orthodontic of orthodontic field, especially palate, upper mandibular dental arch bilateral or unilateral side
Such situation such as constriction；
The utility model has the advantages that bone anchorage provided by the invention expands bow device and its application method, bone anchorage is expanded by plantation nail and is bent
Device is fixed together, and forms an entirety, and during correction, stress area is all concentrated on around plantation nail, is formed absolute
Bone effect expand bow.In addition, having overturned traditional way that rotation hole is arranged at middle axis center, the side of spanner drive is used instead
On the one hand method reduces the stress condition of lever stress point, increase wear comfort, be on the other hand provided with two kinds of amplitudes of size
Strength of adjustment increases a kind of new correction course for the treatment of option, that is to say, that traditional correction is treated on the basis of device is bent in traditional expansion
Journey option is usually that in the morning, afternoon and evening, rotation a quarter is each, or sooner or later, the such selection of rotation half circle, and this hair
The a quarter circle or half circle of the bright a quarter circle for increasing rotation ringlet or half circle and great circle, even
It can be used in combination with size circle, mainly be decided by the practical correction demand of patient, select more diversified, better effect.Furthermore
The present invention bends device enhanced strength than traditional expansion, mainly opens functional hole at middle axis center in the prior art, reduces axis
Intensity, and not only not aperture at middle axis center of the invention, also add reinforcing rib block, so that the intensity of axis significantly mentions
It rises, and then improves the intensity that entire bone anchorage expands bow device.
