利用压膜式活动矫治器压入下颌第一、第二磨牙1例

摘要

本文报道1例左上颌第一、第二磨牙缺失较长时间后对118226rn第一、第二磨牙伸长,因修复间隙不足而采用压膜式活动矫治器配合正畸橡皮圈持续施轻力进行左下颌第一、第二磨牙的压低,从而获得足够的间隙完成种植牙修复,建立良好稳定的咬合关系.%This case report focused on a patient with supraeruption of the first and second mandibular molars as a result of loss of the first and second maxillary molars for a long time. We adopted a combination of a vacuum-formed removable appliance and elastics to intrude the first and second mandibular molars by using a continuous, light force to acquire sufficient restoration space for maxillary molars. Thus, the dental-implant treatment was successful, and a good and stable occlusal relationship was established.
