摘　　要：双[牙合]垫矫治器(Twin-Block)是用于治疗生长发育期下颌后缩患者的传统矫治器,该矫治器使下颌功能性前移位,促进下颌生长,改善面部美观。Twin-Block矫治后软组织的改变包括:颏唇沟变浅,下唇、软组织颏顶点、软组织颏前点的向前移位等,但鼻唇角及唇的变化仍存在争议。目前多数对于软组织测量的研究限于头影测量及面像照片,三维面部扫描技术提高了软组织变化研究的准确性与便捷性并且无辐射,是研究Twin-Block矫治器后软组织变化的新方法。此外,Twin-Block对于软组织的矫治效果的长期稳定性仍不清楚,需要在更可靠的纵向研究中进行评估。The Twin-Block appliance is a traditional orthodontic device used for treating patients with mandibular retrognathia during the growth and development phase.This appliance moves the mandible forward functionally,promotes mandibular growth,and improves facial aesthetics.The soft tissue changes after Twin-Block treatment include a shallowing of the mentolabial fold,forward displacement of the lower lip,soft tissue chin point,and soft tissue pogonion.However,changes in the nasolabial angle and lips remain controversial.Currently,most studies on soft tissue measurements are limited to cephalometric analysis and facial photographs.Three-dimensional facial scanning technology has enhanced the accuracy and convenience of soft tissue change research,and it is radiation-free,offering a new method for studying soft tissue changes after Twin-Block treatment.Furthermore,the long-term stability of the soft tissue correction achieved by Twin-Block is still questionable and needs to be evaluated in more reliable longitudinal studies.
