The upper front teeth and the teeth next to the front teeth It is also affecting the perspective, which is the focus of the dentition correction. The traditional orthodontic correction device generally has a tooth plate attached to the outer surface of each tooth that is inferior, and the tooth plate is glued. On the other side of the tooth, the common string is to be corrected to form a correction line with the same shape of the dentition curve, and then the two ends of the correction line are respectively pulled to the back of the tooth and the bone nail is fixed, and the correction line itself has a slight material elasticity to adjust the absorption. The resistance of the teeth to the corrective force is affected by the corrective force of the corrector. After a certain period of life, the tooth is pulled and corrected, and then the orthosis is removed to reveal the corrected dentition. The orthodontic device for forcing the teeth to be corrected by the physical elastic force can only pull the occlusal end of the upper anterior teeth to the throat direction. Although the front teeth of the upper teeth are neat and beautiful, the roots are not When moved back, or even because only the teeth bite to the throat end direction of traction, and tooth root as a seesaw-like displacement direction but the anti yearning estuary, causing tooth The negative effect of the exposed or convex appearance of the root.

In view of the fact that the conventional orthodontic device achieves the purpose of correcting the alignment of the dentition, but the lack of exposed roots or the appearance of the convexity, the inventors actively study the improvement, after a arduous process of invention, Finally, the invention has been produced.

In the absence of the present invention, the lingual anterior traction device is constructed by a plurality of tooth plates, a correction line, at least one pair of bone nails, a pair of continuous shackle bodies, and a pair of elastic traction members, which are in the middle of the correction line. The tooth plate is fixed in series with the correcting tooth pitch, and the straightening line is adjacent to the outer end of the two tooth plates which are connected at the farthest side, respectively, and is bent upward for a length, and then twisted and looped back slightly away from the direction of the arranged tooth plate. After stretching, the nails are fixed on the inner side of the teeth and the upper nails are fixed on the inner side of the teeth. When the upper jaws are fixed on the inner side of the upper teeth, the other side of the tooth plate is fixed to the other side. Corresponding to the upper tooth back, and the back of the tooth plate back of the back of the two sides are respectively welded with a continuous shackle body, so that the continuous shackle body is placed against the back of the side door and the tooth of the back of the incisor. Fixing the ends of the line with at least one pair of bone nails to make the correction line The torque of the upper row of the teeth is displaced in the direction of the throat, and the nail is fixed at the fixed point position in the past, and the hook body of the continuous hook body is hooked to one end of the elastic traction member, and the elastic traction member is hooked to the continuous hook. The other end of the ring body is sleeved and then nailed, so that it can more effectively pull the upper front teeth and the roots of the teeth to the throat. Yes, this is the purpose of the present invention.
