Width of two sliders is equal to the width of the groove trench, the positioning grooves are arranged at the end face of two sliders, the handles are arranged at one end of the sliders, the gaps having equal width with the groove trench are respectively arranged at position of two sides of the cover plate which are perpendicular to the groove trench, wherein the two sides are corresponded to the groove trench, the through holes which enable movable fit with the sliders are arranged between the bottom of the gap at one side of the cover plate and the bottom of the gap at other side of the cover plate, the ends without arrangement of the handles of two sliders are respectively inserted in the through holes from two ends of the through hole arranged on the cover plate and then are positioned by the positioning bolts, and thereby the groove trench length can be adjusted by adjusting the length of two sliders which stretch out of two ends of the through holes.
Description
Technical field
The invention belongs to orthodontic utensil technical field, particularly a kind of bracket of orthodontic.
Background technology
Bracket is the utensil that orthodontic treatments must use, and at present in Buccodental orthodontic treatment process, is normally fixed on facing by bracket, by the work groove of arch wire through bracket, uses ligature of steel wire or elastic tape ligation directly to force in and rescues arch wire.The mode of this type of bracket and employing ligature of steel wire or elastic tape ligation produces larger pressure to rescuing arch wire, hampers the normal movement of arch wire, thus not only easily affects orthodontic treatment effect, and easy patient harm oral mucosa.For the problems referred to above, the existing many parts of patent applications about locking bracket are open, and described locking bracket arranges bracket lid to be defined in work groove by arch wire.But disclosed locking bracket, no matter be active or passive-type, its groove length is all fixing, cannot carry out adjustment change.But, in the orthodontic treatment process of tooth, sometimes need shorter groove to be beneficial to the movement of tooth to reduce friction, sometimes then need longer groove with increasing friction force thus be beneficial to the protection etc. of anchorage in Tooth Movement process.Therefore, existing locking bracket is difficult to meet the different requirements to frictional force in correction process, affects the efficiency of orthodontics.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of groove length-adjustable self-locking bracket for tooth orthodontic, to solve the problem adjusting groove length in orthodontic treatments process under the condition not changing bracket as required.
The length-adjustable self-locking bracket for tooth orthodontic of groove of the present invention, comprise base, be fixed on the cell body on base, be arranged on the groove for installing arch wire on cell body, be arranged on cell body for cover groove cover plate and for regulating two draw runners of groove length, the width of two draw runners is all identical with the width of groove, the end face of two draw runners is provided with locating slot, one end of two draw runners is provided with pull handle, described cover plate corresponds to the position of groove perpendicular to the both sides of groove and is respectively arranged with the breach identical with slot width, the indentations bottom of cover plate side to cover plate opposite side indentations bottom between be provided with the through hole being with draw runner to coordinate, two draw runners do not arrange described through hole two ends that pull handle end arranges from cover plate respectively and to insert in this through hole and to locate with pilot pin, the length at through hole two ends is stretched out by regulating two draw runners, realize the adjustment of groove length.
The length-adjustable self-locking bracket for tooth orthodontic of groove of the present invention, the total length of two draw runners can be shorter than the length of the through hole arranged between cover plate side indentations bottom to cover plate opposite side indentations bottom, also can=cover plate side indentations bottom to cover plate opposite side indentations bottom between the length of through hole that arranges, preferably total length=cover plate side the indentations bottom of two draw runners is to the length of the through hole arranged between cover plate opposite side indentations bottom.
The length-adjustable self-locking bracket for tooth orthodontic of groove of the present invention, cover plate perpendicular to groove both sides correspond to groove position set by notch length can be identical, also can be different, the notch length that preferred cover plate corresponds to set by the position of groove perpendicular to the both sides of groove is identical; The length of two draw runners can be identical, also can be different, and preferably the length of two draw runners is identical.
From integrally-built coordination and consideration easy to use, the length-adjustable self-locking bracket for tooth orthodontic of groove of the present invention, cell body is perpendicular to being provided with the guide groove with cover plate combination inside the two ends of groove, and cover plate arranges both sides jaggy and is inserted in described guide groove, forms the combination of push-and-pull slidingtype.
The length-adjustable self-locking bracket for tooth orthodontic of groove of the present invention, cell body is also provided with ligature via hole, and described ligature via hole is two, lays respectively at the both sides of groove.
The length-adjustable self-locking bracket for tooth orthodontic of groove of the present invention, can use rustless steel, bioceramic or reserch of dental composite resin material to make.
The length-adjustable self-locking bracket for tooth orthodontic of groove of the present invention, by regulating two draw runners to stretch out the length at through hole two ends, realizes the adjustment of groove length.When two draw runners are arranged in through hole completely, the length of groove is the shortest (see Fig. 5); Along with two draw runners or one stretch out the change of the length of through hole, the different groove of different lengths (see Fig. 6, Fig. 7) can be formed.
The present invention has following beneficial effect:
1, under the condition not changing bracket, can need the length regulating bracket groove easily according to orthodontic, to change frictional force, that improves orthodontic rescues usefulness.
2, can optionally one-sided change bracket groove length, thus be conducive to the rectification reversing tooth.
3, pass for ligature owing to being provided with ligature via hole on the cell body of groove both sides, thus strengthen maintenance by ligature when needed.
