Abstract
The utility model relates to a supporting alveus for teeth orthodontic treatment, which comprises a bottom plate and a supporting alveus body fixedly connected to the bottom plate. The middle part of the supporting alveus is provided with a square alveus slot which parallels with the bottom plate. The square alveus slot is used to clamp and hold an orthodontic bow wire. In order to simplify a treatment operation, the square alveus slot of the supporting alveus body slants a definite angle in a horizontal and a vertical directions. Namely, the included angle of an alveus slot and the horizontal midline of the supporting alveus body is in a range of 0.8-22.9 DEG and the included angle of the alveus slot and the vertical midline of the supporting alveus body is in a range of 1.5-9.4 DEG. A bow wire can directly clamped in the alveus slot with running a torsion firstly when set. The bow wire can produce a definite torsion force after ligated fixedly, which corrects the positions of teeth.
Description
This utility model belongs to dental instrument, is a kind of bracket that is exclusively used in the orthodontic treatment.
At present, it all is that orthodontic bracket is attached to dental surface that child or juvenile tooth are carried out orthodontic treatment, then the utility arch ligation is fixed on the bracket, and the elastic deformation force by arch wire is subjected to displacement tooth, to reach corrigent purpose.Existing orthodontic bracket is made up of base plate and the supporter groove that connects firmly on base plate, and a square groove parallel with base plate is arranged at the middle part of supporter groove, is used to place utility arch.But this groove all is to overlap with the horizontal central line and the median vertical line of supporter groove with vertical direction in the horizontal direction, and promptly angle is zero.Therefore, before settling arch wire, need in advance square arch wire to be reversed certain angle along horizontal and vertical, and this operation is carried out often by hand, concrete operation is trouble, and is difficult for grasping.
The purpose of this utility model provides a kind of orthodontic bracket of simplifying the orthodontic treatment operation.
Solution of the present utility model is: the orthodontic bracket that is provided also is made up of base plate and the supporter groove that connects firmly on base plate, at the supporter groove middle part a square groove parallel with base plate is arranged, and these are all identical with existing bracket.Special character of the present utility model is groove on the supporter groove laterally and certain angle that all tilted on the depth direction, that is: the angle β of groove and supporter groove horizontal central line is 0.8-22.9 °, with the angle α of supporter groove median vertical line be 1.5-9.4 °.α and β angle value are according to Chinese tooth structure and definite.So need not arch wire is reversed in advance when settling utility arch, square arch wire directly sticks into quadrate groove, can produce certain twisting resistance after ligation is fixing, with the state of crooked orthodontics to standard.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is user mode figure of the present utility model.
As shown in Figure 1 and Figure 2: bracket base 1 is a square plate, and its bottom surface has many grooves, is used to adhere to binding agent, so that bracket is sticked on dental surface, supporter groove 2 is a T shape structure, and its middle part has square groove 3.The inclination angle of groove 3 on depth direction, promptly the angle with the median vertical line of supporter groove is α; Inclination angle in the horizontal, promptly the angle with the horizontal central line of supporter groove is β.As previously mentioned, the value of α and β is to determine according to the construction features of Chinese's tooth.When carrying out orthodontic treatment, normally some teeth are carried out together just abnormally, promptly each dental surface is all pasted bracket, and orthodontic bow-wire 4 strings are stuck in the bracket groove of each tooth (as shown in Figure 3).The fixing usefulness that is used for the arch wire termination after wherein first and second is ground one's teeth in sleep and upward overlaps; Other tooth is pasted bracket separately, is used for just abnormal.The concrete optimal values of α and β is as follows: following central incisor is 1.5 ° and 1.5 °; Following lateral incisor is 1.8 ° and 0.8 °; The lower jaw canine tooth is 4.2 ° and 8.2 °; The lower jaw first bicuspid is 6.2 ° and 17 °; The lower jaw second bicuspid is 9.4 ° and 22.9 °; Last central incisor is 2.3 ° and 9.2 °; Last lateral incisor is 4.9 ° and 7.6 °; Eye tooth is 6.3 ° and 4 °; Upper jaw first bicuspid is 5.2 ° and 7.9 °; Upper jaw second bicuspid is 8.4 ° and 9.1 °; Above-mentionedly respectively organize in the numeral the former for the α angle, the latter is the β angle.
The utility model has the advantages that: easy to use, the doctor need not arch wire is reversed in advance when treating operation, thereby makes the treatment simplified control, and the effect of orthodontic treatment is also relatively good.
