摘要
目的:探讨下颌磨牙低位近中、水平阻生的矫治方法和效果。方法:采用直丝弓矫治器,在阻生磨牙近中相邻磨牙带环上焊接悬吊竖直簧,对14例下颌第三磨牙,6例下颌第二磨牙共30个阻生磨牙(其中水平阻生12个、近中阻生18个)进行牵引竖直。结果:阻生磨牙均被快速竖直,排齐整平后纳入治疗系统。竖直磨牙时间1~5个月,平均3个月。X线片显示阻生磨牙周围牙槽骨生长、恢复良好。结论:悬吊竖直法能高效、快速、简便地竖直低位阻生磨牙,并具有同期矫治(不延长矫治期),有效增强支抗和竖直支抗磨牙的优点。
Objective:To study treatment method of horizontally impacted and mesioangularly impacted lower molar erection. Method: 30 impacted molars(12 horizontal impaction and 18 mesionangular impaction) were treated with suspension and erection. Result: All impacted molars were erected quickly and brought into treatment system. Erection time was 1-5 months, average being 3 months. Panoramic radiograps showed that periodontal health of impacted molars periphery was good.Conclusion: The method of suspension and erection can quickly and conveniently erect lower impacted molars and have merits of synchronizational treatment,reinforced anchorage and erection of anchorage molar.
