摘要
正畸治疗过程中,前牙转矩不仅会影响前牙区的美观,也会影响后牙咬合关系,因此前牙转矩的控制具有重要意义。如何通过数字化技术控制前牙转矩是目前正畸临床应用的热点问题,而前牙转矩控制的方案设计是许多正畸医生临床操作的疑难和困惑所在。笔者通过文献复习,结合临床病例的研究结果,对个性化唇侧矫治器、个性化舌侧矫治器和透明矫治器3种个性化矫治器的前牙转矩控制特点、要点和设计技巧进行讨论,以期帮助正畸医生了解个性化矫治器,为临床中通过数字化技术设计前牙转矩提供参考。
In orthodontic treatment,the torque of anterior teeth is of great significance,which affects not only the appearance of anterior teeth but also the occlusal relationship of posterior teeth.Thus,how to control the torque of an anterior tooth with digital technology has become a focus of research on orthodontic applications.However,controlling the torque of anterior teeth is difficult,and current designs have been confusing many orthodontists.Basing on the literature and clinical cases,we discuss the characteristics,key points,and design skills of for controlling the torque of anterior teeth of individualized labial appliance,individualized lingual appliance,and invisible appliance,to help orthodontists and provide a reference for the digital design of anterior teeth torque in clinic.
