摘要
无托槽隐形矫治技术问世以来,因其美观舒适,受到患者的欢迎。随着时间推移,隐形矫治材料的不断发展,软件设计的不断更新,矫治病例的难度越来越高。正畸医生有必要提高自己的业务能力,掌控隐形矫治技术的特点,更好地为患者提供舒适美观且有效的治疗技术。该文重点讨论Ⅱ类患者的拔牙矫治的原则,垂直向控制的重要性以及临床相关注意事项,包括拔牙牙位的选择,拔牙间隙的分配,支抗的控制,前牙转矩的控制,后牙的远中备抗等,为广大正畸医生进一步学习掌握这项新技术提供指导。
Since the advent of clear aligner technique,clear aligners have become an increasingly common addition to patients due to its improved aesthetics and comfort.With the development of aligner materials and the innovation of software design,orthodontists are having a better knowledge of clear aligner technique,and the indication of clear aligners has been greatly enlarged with increasing treatment difficulty.It is necessary for orthodontists to improve their professional ability and master the characteristics of clear aligner technology for a better approval of comfortable,esthetic and effective treatment technology for patients.This article focuses on the principles of tooth extraction treatment in ClassⅡcases,the importance of vertical control and relevant clinical considerations,including the selection of extraction site,the distribution of the extraction space,anchorage control,torque control of anterior teeth,anchorage preparation of posterior tooth,etc.,thus providing necessary information for orthodontists to grasp a better understanding of this new technology.
