[Research progress of finite element modeling for clear aligner treatment].

Finite element method, as a verified numerical simulation method, has been widely applied in the biomechanical research of clear aligner treatment. The accuracy of its calculation results is closely related to the construction method of the finite element model. This paper takes the finite element modeling process of clear aligner treatment as a clue, and reviews the modeling methods of relevant research in recent years, aiming to provide reference for subsequent studies.
