Comparison of stress developed on teeth during lingual and labial orthodontics using 3D finite element modeling.

Abstract

Background: The introduction of lingual appliances in orthodontics has led to great improvement in the aesthetic aspect in orthodontics. Lingual appliances have their own specific biomechanics, which are quite different from that of conventional labial orthodontics, and therefore proper care must be taken in their use. The measurement of stress produced at different locations of the root clinically by various types of orthodontic tooth movement is very difficult but important procedure.
