数字化设计镍钛丝推上颌第一磨牙向远中1例

Maxillary Molar Distalization using Digitally Designed Nickel-titanium Wire:A Case Report

磨牙远移是正畸治疗中常用的扩展牙弓长度的方法,本文介绍了一种数字化设计超弹镍钛丝远移磨牙的简易装置,利用弓丝的形变产生矫治力,从而使牙移动。这种矫治装置操作简单,易于清洁,对患者依从性要求低,矫治效果明确。

Molar distalization is frequently used to increase arch length in orthodontic treatment.This article aims to introduce a simple device that uses digitally designed superelastic nickel-titanium(Ni-Ti)wire to achieve maxillary molar distalization.When the NiTi wire is bonded to the tooth surface,its deformation will produce orthodontic force,which makes the molar move.The device is easy to operate and clean.Besides,it requires low patient compliance and it can produce marked effects.
