Abstract
The utility model relates to the structural improvement on a bracket for correcting teeth. Both sides of a support plate are provided with wing hooks with slots, one end of the wing hooks is hinged and provided with a cover plate, and one end of the cover plate is provided with a cover hook mutually matched with the other end of the wing hooks. Therefore, the utility model has the advantages that structure is reasonable, operation is convenient, the friction of a correction and treatment system is reduced, appearance is smooth and beautiful, oral mucosa is not damaged, etc.
Description
This utility model relates to the medical apparatus and instruments that rescue in a kind of oral cavity, especially relates to a kind of structural improvement of rescuing the bracket of tooth.
The beginning of the eighties, taken the lead in from Beijing medical university School of Stomatology since fixed appliances such as the side of application silk bow, filament bow rescue the misfit deformity, rely on it stronger to rescuing the control force that tooth moves, competent Zhi Kangli, enlarge the ability of dental arch greatly, and the control tooth has played immeasurable effect in the sufficient ability that three-dimensional moves in mouth cavity orthodontic is clinical.Therefore, side's silk bow, filament bow fixed appliance use on a large scale in China, and have obtained satisfactory therapeutic effects.
As the bracket of the Primary Component of side silk bow, light round-wire appliance, the side of mainly containing silk bends bracket and straight silk bow supporting groove at present.The both needs with ligation silk or ligation rubber chain arch wire to be fixed in the groove, so exist: 1. clinical manipulation is loaded down with trivial details, and the other working time of chair is long, and each further consultation all needs the ligation silk is removed and ligation again, has influenced work efficiency; 2. the frictional force of the slip of arch wire in groove is bigger, and the energy consumption of rescuing is increased; 3. because the ligation silk leaves stump in the oral cavity, in patient's feed process, might cause the damage of oral mucosa.
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of rational in infrastructure, simple operation, and the frictional force of system is rescued in minimizing, and smooth in appearance is attractive in appearance, not the self-locking bracket of lesion ports transmucosal.
Major scheme of the present utility model is: at the hinged cover plate that is provided with of an end of described pterygoid hamulus, and be provided with lid hook with the other end phase configuration of pterygoid hamulus at an end of cover plate.Wherein, the brace that described cover plate can be by being located at the one end or directly be articulated on the pterygoid hamulus by rotating shaft; Described cover plate also can and place brace and the whole formation of rotating shaft between two pterygoid hamulus.For example, respectively establish the convex body, constitute rotating shaft in the both sides of brace one end.And respectively be provided with the axle bed of opening at an end of described pterygoid hamulus, and also can respectively be provided with poroid axle bed, the rotating shaft of cover plate is placed in one.
In addition, it is protruding to be provided with the wing in the both sides of described pterygoid hamulus, so that the placement of rubber chain and other just abnormal adnexa.
In order to strengthen the adhesive force of the bracket and the flank of tooth etc., can add one deck stainless steel cloth in its bracket bottom, perhaps the channel form lines is set in the bracket bottom.
Therefore, the utlity model has rational in infrastructurely, easy to make, simple operation reduces the frictional force of the system that rescues, and is beneficial to bracket and moves freely along side's silk bow or raw silk rings bow, rescue usefulness thereby improve, and the appearance fairing is attractive in appearance, not characteristics such as lesion ports transmucosal.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Below by embodiment, this utility model is further described.
Supporting plate 2 is 3 * 3.5mm
2Corrosion resistant plate, vertically be provided with several ditch shape grooves 20 below it, to improve the adhesion with the flank of tooth; Both sides on supporting plate 2, be respectively equipped with the pterygoid hamulus 41 of central zone groove 5, the downward crotch in the two ends of pterygoid hamulus and be down shape, wherein an end curves and is similar to the axis hole shape and constitutes axle bed 44, and the wing that is provided with evagination in the both sides of the nearly groove 5 of pterygoid hamulus 41 is protruding 42, so that the installation or the configuration of rubber chain or other just abnormal adnexa.Above-mentioned all structures can adopt technologies such as known line cutting to be processed by stainless steel material integral body.
The same arcuation that is of upper surface of described cover plate 3 and pterygoid hamulus 41, the central authorities of one end are provided with brace 31 and rotating shaft 33.The other end of cover plate 3 is provided with and the match lid hook 32 of (radius of curvature is smaller) of pterygoid hamulus shape.Above-mentioned all structures are to adopt the stainless sheet steel punching press to make.During assembling, only need the lamellar rotating shaft 33 of an end inserted from the slit of the axle bed 44 (or hook-shaped axle bed) that is provided with opening respectively and get final product.
During clinical manipulation, the prefabricated arch wire of method that can be routinely, then according to the needs of just abnormal profile of tooth, place the groove of this self-locking bracket on the arch wire one by one, cover plate 3 again closes, rely on the elasticity of cover plate and the fastening of lid hook and pterygoid hamulus, prevented the problem of cover plate lip cheek, thereby make this utility model make things convenient for, be securely fixed on the arch wire to dislocation.
Equally, in rescuing process,, also only need open the cover plate 3 of this bracket one by one, with said method it is installed on the new arch wire then if need to change arch wire.Thereby the other operating time of clinical chair is shortened greatly, and the patient's number that can rescue in the unit interval can increase, and has alleviated the time that just abnormal patient preengages wait, and more patient can be rescued timely.
