Description

Traction arch expansion device for occlusion of upper anterior teeth and stenosis of dental arches of children

Technical Field

The utility model relates to the technical field of tooth orthodontics, in particular to a traction arch expansion device for children upper anterior tooth burial survival and dental arch stenosis.

Background

The description of the background art of the present invention pertains to the related art related to the present invention, and is only for the purpose of illustrating and facilitating the understanding of the contents of the present invention, and it is not to be understood that the applicant definitely considers or presumes that the applicant considers the present invention as the prior art of the application date of the present invention which is filed for the first time.

The buried impacted tooth is a more complex malocclusion deformity in orthodontics clinic, the treatment difficulty is high, and the surgical windowing and sprouting guiding combined orthodontic traction treatment is the most commonly used treatment method. Orthodontic traction treatment can be generally divided into four steps of gap opening, surgical windowing and guiding, attachment bonding and correction, traction stress application and orthodontic alignment. The adult develops the clearance and usually uses the fixed ware of correcting, aligns adjacent tooth, uses the spiral to push away the spring and prepares enough clearance for the tooth that buries, and the main arch wire of enough size is stable, then carries out the surgery and windows the guide sprout operation, and the annex is corrected in the bonding, draws the thrust augmentation on main arch wire. However, in children in the growing stage, the anterior teeth are often buried and arrested after the incisors and the lateral incisors erupt in the mixed dentition stage. If the fixed appliance is used for developing gaps, the deciduous teeth are easy to loosen and fall off, and anchorage is easy to lose, so that the best effect cannot be achieved. The development of the direction, force value and speed of the gap and orthodontic traction by scientific design and the effective control of anchorage and the like become important and difficult points concerned by the technical field.

Arch expansion is an effective way to increase arch width and thereby obtain clearance. At present, the clinical bow-expanding device has a plurality of structures, some structures comprise more parts and have poorer comfort, and some structures comprise fewer parts, have insufficient tension, have poorer retention and have unobvious bow-expanding effect. In addition, the existing traction device has the problems of single direction, difficult control of anchorage and the like.
