Lingual anterior teeth retractor

Abstract

The invention discloses a lingual anterior teeth retractor, which is composed of tooth plates, a straightening line, a bone nail, continuous shackle bodies, and an elastic traction member. The tooth plates are connected in series and bonded one to one at a spacing of the straighten teeth in the middle of the straightening line. When the nail is fixed on the upper jaw on the inner side of the upperrear teeth, the other sides of the tooth plates bonded to the straightening line are bonded to the corresponding upper tooth backs by adhesive. The continuous shackle bodies are welded to the back sides of the tooth plates bonded to the front teeth on both side so that the continuous shackle bodies are abutted against the side front tooth backs and the gingiva of the front tooth backs, thereby fixing the two ends of the straightening line with at least one pair of bone nails. Thus, the straightening line generates the torque to pull the upper row of tooth roots to the throat. A bone nail canbe also nailed to a predetermined position of the upper jaw. A hook of the continuous shackle body is hooked to one end of the elastic traction member, and the other end of the elastic traction memberhooked to the continuous shackle body is sleeved a nailed bone nail so that the upper anterior teeth with their roots can be pulled to the direction of the throat.

Description

technical field [0001] The invention belongs to the technical field of dental appliances, and in particular refers to a lingual anterior tooth retractor, which is used for patients with irregular growth of the upper row of teeth, such as sharp front teeth, to pull the teeth for a certain period of time until the upper row of teeth is arranged neatly. The newer and better upper teeth aligner. Background technique [0002] It is not that everyone is born with a pair of neatly arranged teeth, but many people naturally see a few teeth that are crooked or have too large gaps when they open their mouths. Among them, the upper front teeth and the front teeth Teeth affect the view even more, so they become the key orthodontic parts for patients with irregular dentition. Traditional orthodontic orthodontic devices generally have a tooth plate attached to the outer surface of each inferior tooth, and the tooth plate is glued. On the other side of the upper teeth, the correction wires...

[0002] It is not that everyone is born with a pair of neatly arranged teeth, but many people naturally see a few teeth that are crooked or have too large gaps when they open their mouths. Among them, the upper front teeth and the front teeth Teeth affect the view even more, so they become the key orthodontic parts for patients with irregular dentition. Traditional orthodontic orthodontic devices generally have a tooth plate attached to the outer surface of each inferior tooth, and the tooth plate is glued. On the other side of the upper teeth, the correction wires to be corrected into the same shape of the dentition curve are glued together, and then the two ends of the correction wires are respectively snare bone screws and pulled to the gum bone nails of the rear teeth to fix them, and the correction wire itself has a slight material elasticity. It adjusts and absorbs the resistance of the teeth to the orthodontic pulling force. After the orthodontist wears the aligner between the lips and teeth for a certain period of time, the affected tooth is pulled and corrected, and then the aligner is removed to reveal the corrected dentition. However, with this orthodontic device that uses physical elastic tension to force the teeth to be corrected, the occlusal end of the protruding upper front teeth can only be pulled back toward the throat. Although the front row of the upper teeth is neat and beautiful, the roots of the teeth have not moved back at the same time. , even because only the occlusal end of the teeth is pulled towards the throat, while the roots of the teeth are displaced in the opposite direction to the outside of the mouth like a seesaw, resulting in the negative effect of exposed or protruding teeth.

[0003] In view of the fact that after the traditional orthodontic device achieves the purpose of correcting the beautiful alignment of the dentition, it leaves the exposed or protruding and unsightly defects of the tooth root, the inventor is actively researching the way to improve it. Finally there is the invention
