摘要 目的观察在牙矫治过程中,应用非拔牙技术Smart-Clip自锁托槽的疗效,对比牙弓形状在治疗前后的形态变化,寻求Smart-Clip自锁托槽治疗后牙弓形态相关参数变化的矫正特点。方法对牙齿比较拥挤的患者采用自锁托槽进行非拔牙矫治,观察矫正前后牙弓形态发生的变化。结果 Smart-Clip自锁托槽会明显增加牙弓的长度与宽度,牙弓宽度增加主要发生在前磨牙区。上颔中切牙唇向前移动的量和向后移动的量对比,差异无统计学意义(P>0.05),牙弓变化和牙列拥挤度有直接关系。结论在牙矫治过程中,应用非拔牙技术Smart-Clip自锁托槽的矫治效果显著,后牙可增加牙弓的长度和宽度,上颔切牙移动和磨牙中移动可增加上颔牙弓长度。
