Abstract:

No-brackets invisible appliances is transparent elastic plastic removable orthodontic appliances，which is designed and manufactured by computer based on the occlusal condition of patients. It works by the multifunctional attachments bonded on the teeth，and patients should wear in sequence，replaced every 1-2 weeks，and gradually achieving the purpose of correcting malocclusion. With the development of materials science，computer science，biomechanics and other relative disciplines and techniques，this new orthodontic technique will continue to develop，improve and get more and more widely applied.

Key words: orthodontics, invisible appliances, no-brackets

摘要：

无托槽隐形矫治器是根据每例患者的牙颌情况，通过计算机辅助设计和制作的透明弹性塑料活动矫正装置，辅以黏结在牙面上形态各异发挥各种作用的附件，患者按照顺序进行佩戴，每1 ~ 2周更换1副，逐渐达到矫治错牙合畸形的目的。随着材料学、计算机科学、生物力学等相关学科的发展，无托槽隐形矫治技术将不断发展、完善，得到更多更广泛的应用。
