Abstract
The simulations by the finite elements method have expanded their field of
application and proved to be efficient in areas of engineering and in the field of
biomechanics. In this work, tree-dimensional models were created based on the
average dimensions of dental units, as found in specialized literature. Different initial
dental movements, induced by the application of orthodontic force by means of treedimensional
finite elements models, were evaluated. The produced movements were
found to be correspondent to literature. At the same time as dental movements were
quantified, it was possible to evaluate the axial stress along periodontal fibers, which
made it possible to emphasize which of the tooth dental socket wall areas will be able
to promote bone remodelling. Determining quantitatively the initial dental movements
made it also possible to verify the influence of the use of stainless steel wire
ligatures, the inclusion of the second molars and the most adequate local to installing
orthodontic mini-implants. Since different intra and extra-oral appliances were
considered, the movements caused in the distalization of the molars and adjacent
teeth were as determined, allowing to evaluate the efficiency of the utilized
orthodontic appliances. Thus, it can be concluded that the utilization and adequate
construction of tree-dimensional finite elements models make possible the realization
of orthodontic studies that quantitatively confirm the data found in the literature, in
addition to permitting the evaluation of the behavior of new kinds of appliances and
orthodontic techniques, fostering research and studies in the field of Dentistry.
