Summary of the invention

The utility model proposes a kind of fixed vertical device of grinding one's teeth in sleep of impaction of leaning forward of grinding one's teeth in sleep of correcting down, its purpose is intended to overcome the above-mentioned defective of existing in prior technology.

Technical solution of the present utility model: it is characterized in that comprising linguoplate, hyoid arch, band, hyoid arch welding section, be surrounded by the far away middle hook connector of self curing plastic, middle hook far away outward, wherein the leading portion of hyoid arch is embedded in the linguoplate of being made by self curing plastic; The postmedian of hyoid arch is bent into a hyoid arch welding section and with silver soldering it is welded on the tongue side of band; The back segment of hyoid arch continues extension in far away, hook connector during formation is far away, and middle hook connector far away outside is coated with self curing plastic; The hook connector continues rearward to extend and hook in the back zone of grinding one's teeth in sleep forms far in far away.

Advantage of the present utility model: 1) size and Orientation of pull strength can be adjusted as required, and this both can make the trouble tooth break away from stopping of adjacent teeth smoothly, can avoid taking place in this tooth setting process disadvantageous elongation again; 2) anchorage is reliable: owing to whole traction apparatus is to improve on the hyoid arch basis, the counteracting force of corrective force is born jointly by whole dental arch and anterior alveolar process, and pull strength generally can not cause the forfeiture of anchorage; 3) need not label dress and wear band suffering from the sound of baby talk, as long as suffer from the sound of baby talk hat exposed face be arranged, the tongue side that can bond button can begin traction correcting, even for hiding the resistance survivor fully, also can reach this purpose by cutting the gum expose portion corona of boning; 4) the sealed case of one-sided and bilateral all is suitable for.

It should be noted that suffering from tooth should keep a period of time after vertically, reach fashionable dress then and wear band and carry out fixed orthodontic, in order to avoid the recurrence of leaning forward.The problem that whether will pull out about following third molar: generally speaking, all need to descend in advance third molar to pull out.But do not have obvious resistance if show third molar down on orthopantomography or the CT sheet for second molar vertical motion down, then can pull out.
