Abstract

The utility model relates to a torque support trough for tooth correction, which is an instrument for tooth deformity orthodontics. A square wire trough and a ligation trench are arranged on the support trough body; the bottom of the support trough body is provided with a binding trench; the vertical central line of the square wire trough and the vertical central line of the support trough body form an alpha slope angle; square arch wires are embedded in the square wire trench, and generate torque to rotate tooth shaft slantways, so that the deformity correction purpose is achieved. The utility model has the advantages of convenient treatment, light discomfort of a patient and low treating cost.

Description

Torque support trough for tooth correction

A kind of orthodontics torque slot bracket of this utility model relates to the dental utensil, the appliance that specifically a kind of orthodontic is used, and supporter groove is provided with square shred groove and ligature furrow, and the supporter groove bottom surface is provided with the bonding ditch.

The orthodontics torque slot bracket that existing a kind of child of being used for or teenager straightening of teeth are used, its structure is shown in Fig. 1-4, and supporter groove is provided with square shred groove and ligature furrow, and the supporter groove bottom surface is provided with the bonding ditch.When carrying out orthodontic, the supporter groove bottom surface is bonded in respectively on patient's the lateral surface of preceding incisor, lower incisor, two light tooth and lateral incisor earlier with adhesive glue, again just abnormal square arch wire is embedded in the square shred groove on each supporter groove, and by ligature furrow with bounding wire with square arch wire ligation jail, each supporter groove is connected as a single entity.Because the vertical centrage of square shred groove of prior art is parallel with the vertical centrage of supporter groove,, bring certain difficulty to reversing tooth axle inclination rectification so, just must just can reach the tilted teeth axle is reversed axial purpose by additional auxilliary bow for correcting abnormal tooth.

The purpose of this utility model is exactly the deficiency that overcomes above-mentioned prior art, discloses a kind of improvement structure of orthodontics torque slot bracket, can save just energy straightening of teeth of auxilliary bow, and convenient treatment reduces patient's sense of discomfort, reduces medical expense simultaneously.

A kind of orthodontics torque slot bracket of this utility model, supporter groove is provided with square shred groove and ligature furrow, the supporter groove bottom surface is provided with the bonding ditch, and realize that the technical scheme of this utility model purpose is: the vertical centrage of its square shred groove and the vertical centrage of supporter groove are inclined angle alpha.When using the torque slot bracket of this utility model orthodontics to correct the abnormal tooth of the vertical inclination of patient (as evagination or interior button), the interior generation of square shred groove that can directly utilize square arch wire to embed inclination reversed the tooth axle to the torque of supporter groove, reach just abnormal purpose, and needn't add auxilliary bow again, realized the purpose of this utility model.

Below in conjunction with accompanying drawing a kind of orthodontics torque slot bracket of this utility model and embodiment are described in further detail.

Figure 15 looks sketch map for the left side of Figure 13.

Existing a kind of orthodontics torque slot bracket, shown in Fig. 1-4, supporter groove 1 is provided with square shred groove 2 and ligature furrow 3, supporter groove 1 bottom surface is provided with bonding ditch 4, the vertical centrage of its square shred groove 2 is parallel with the vertical centrage of supporter groove 1, bonding ditch 4 is bar shaped, and supporter groove 1 bottom surface has radian R, and favourable the applying with the tooth lateral surface that has radian bonds.

An embodiment as the torque slot bracket of this utility model orthodontics, shown in Fig. 5-8, supporter groove 1 is provided with square shred groove 2 and ligature furrow 3, supporter groove 1 bottom surface is provided with bonding ditch 4, difference with the prior art is that its vertical centrage of square shred groove 2 and the vertical centrage of supporter groove 1 are inclined angle alpha, square arch wire embeds in such square shred groove 2, the reuse bounding wire utilizes ligature furrow 3 that square arch wire is fixed, each supporter groove 1 is connected as a single entity, promptly can produce torque to the supporter groove 1 that is bonded on the tooth lateral surface, as the power of orthodontic, general α gets 2-12 ° and can satisfy just abnormal requirement, can be according to the different lopsided angles of tooth, suitably choose this utility model orthodontics torque slot bracket of the α value of adaptation, treatment is convenient, and patient's sense of discomfort is light, and medical expense is low.

Consider that the abnormal tooth of some patients also is attended by the twisted tilted deformity of facing, a preferred embodiment as the torque slot bracket of this utility model orthodontics, shown in Fig. 9-12, the longitudinal centre line of its square shred groove 2 also is angle of inclination beta with the longitudinal centre line of supporter groove 1, square arch wire embeds in such square shred groove 2, not only produce the tooth of the vertical inclination of the favourable rectification of torque on vertical, also produce vertically twisted tilted tooth of the favourable rectification of vertical torque simultaneously, general β gets 1-15 ° and can satisfy just abnormal requirement, can suitably choose this utility model orthodontics torque slot bracket of the β value of adaptation according to the different vertical lopsided angles of tooth.

Consider that prior art supporter groove 1 bottom surface is provided with bar shaped bonding ditch 4, (as shown in Figure 3), for further enlarging supporter groove 1 bottom surface and the agglutinating contact area of tooth lateral surface, change the preferred embodiment of rectifying bracket as this utility model orthodontics, shown in Figure 13-15, the bonding ditch 4 that preferably is provided with on supporter groove 1 bottom surface increases supporter groove 1 bottom surface of this utility model orthodontics torque slot bracket and the bonding contact area of tooth lateral surface as far as possible for latticed, makes bonding more reliable.
