Abstract [eng] Orthodontic tooth movement is usually character- ized by two centers: the centre of resistance and the centre of rotation. This paper reports on studies hypothetical mechanical representation of the periodontal ligament (PDL) which plays the most significant role in tooth mobility. The model assume a nonlinear material properties of PDL by means of nonlinear dependence of stresses on strains. Results were obtained by applying the finite element method (FEM) on a lower jaw canine. It was found that the nonlinear PDL locate centre of resistance apically 0.4 mm in comparison with those obtained with linear PDL.
