Abstract:

Since the first appearance of clear aligners, the clear aligner technique has gained increasing interest of patients due to its aesthetic advantages. With the development in biomechanic features of the clear aligner material and innovations of digital design software, orthodontists’ understanding of clear aligner technique has been improving to a greater extent. Clear aligners have many advantages on molar distalisation, such as bodily movement, high efficiency, comfort, and high compliance. This article presents typical patients using molar distalisation approach, and discuss the treatment tactics on molar distalisation, including indication, attachment, staging and use of elastics, aiming to offering practical strategies for orthodontists who want to master the clear aligner technique in molar distal movement.

Key words: clear aligner treatment, molar distalisation, vertical control
