In cases where a retainer can not function symmetrically despite the symmetrical position, it is the case that the teeth of the chair have an asymmetrical position in the anterior-posterior dimension.

We explored this idea with the help of two friends, Professor Kizilova from the Warsaw University of Technology and Dr Yurij Romashov from Kharkov University (Ukraine), and after judging in Vol. 18, No. 4, 2016

Act of Bioengineering and Biomechanics

In this paper, the effects of anterior-posterior asymmetry of the position of molars are evaluated by two computational approaches and finite element method.
