Description

Multifunctional adhesive type orthodontic draw hook

Technical Field

The utility model relates to an orthodontic field in the mouth, in particular to a multifunctional bonding orthodontic draw hook capable of realizing the movement of different positions of teeth.

Background

Along with the increasing importance of people on the beautiful appearance of teeth, the research on the tooth fixing and correcting technology is gradually deepened, the tooth orthodontic technology (also called as tooth correction) is gradually developed, orthodontics mainly researches the etiology and mechanism of malocclusion deformity, diagnoses, analysis, prevention and treatment, and different correcting methods can be adopted for different malocclusion deformities. The fixing appliance used in daily life comprises a bracket, a buccal tube, an arch wire, a planting nail, a traction hook and the like. The bracket and the buccal tube are respectively bonded on the surface of the dental crown; the arch wire passes through brackets or buccal tubes on different dental crowns to connect the arch wire, and the arch wire is used as a force application device for aligning teeth and a 'rail' in the process of moving the teeth; the traction hook is an important component of the oral appliance as a carrier for applying the correction force, and the traction attachment has an adaptive range including adduction of maxillary anterior teeth, closing of tooth extraction gaps, correction of black triangle of adjacent teeth, implementation of parallel movement of molar teeth and anterior molar teeth, elastic traction between jaws and the like.

In orthodontic treatment, the main purpose of the use of a hook is to apply a corrective force to the teeth to move them, so that a fixed support point must be fitted when correction is performed. In orthodontics clinic, a micro screw (called zygomatic bone nail for short) is implanted under the zygomatic bone of the upper jaw or in the buccal shed area of the lower jaw, or a micro screw is implanted on the alveolar bone between adjacent teeth, or a carrying pole arch is assembled to be used as a supporting point of a traction hook, then a rubber chain or a tension spring is hung between the supporting point and the traction hook, and the teeth are moved by elastic traction. In the orthodontic process, according to different treatment conditions, the tooth root control movement, the tooth overall parallel movement and the tooth crown control movement (inclined movement) need to be carried out. The existing traction hook mainly comprises a traction hook arranged on a bracket and a traction hook arranged on an arch wire, wherein the traction hook arranged on the bracket generally comprises a traction hook integrally formed with the bracket, or a traction hook formed by utilizing one end of a ligature wire, or a traction hook inserted in a vertical pipe of the bracket; the archwire-mounted hooks are typically clamped in place against the orthodontic main archwire (square wire). In any installation mode, the traction hook is not directly contacted with the teeth, so that force cannot be directly applied to the teeth, and the force application effect cannot be ensured; in addition, the height of the existing traction hook is fixed and unchanged, the traction hook can only be applied to traction movement under one condition generally, particularly the traction hook arranged on a bracket, in order to enable the correcting force to be directly acted on a target tooth, the volume of the traction hook is small, and a patient feels comfortable when the traction hook stimulates surrounding tissues little, the height of a hook of the traction hook arranged on the bracket from the bracket is only about 2mm, and because the force application points of the traction hook are all positioned at the level of a dental crown, the impedance center position of the tooth is approximately positioned at the junction of 1/3 on the root of the dental root and 1/3 in the root, the tooth mainly shows inclined movement under the action of the traction force, namely the dental crown moves towards the stress direction, and the dental root moves away from the stress direction, so that the integral translation or root control movement of the.
