AI Technical Summary

Technical Problem

In the current anterior crossbite correction appliance, the tongue exerts a greater pushing force on the lower teeth during the correction process, which prolongs the correction period and affects the correction effect.

Method used

An anterior crossbite correction appliance was designed, which adopts a combination structure of base and tongue rail. The base is equipped with push spring and arrow clasp, and the tongue rail separates the tongue and mandibular teeth, reducing the pushing force of the tongue on the mandibular teeth. At the same time, the push spring enhances the pushing and correction effect on the maxillary teeth.

Benefits of technology

By reducing the force of the tongue pushing against the lower teeth and increasing the force pushing against the upper teeth, the effectiveness of the orthodontic appliance is improved, the treatment period is shortened, and the treatment result is enhanced.
