Resumo
This article compares the orthodontic movement obtained by specific external loading conditions using computational models and an experimental test of an ex vivo swine tooth (premolar). A simplified three-dimensional computer model considering linear elastic material behavior working with isotropic properties is assumed with a geometry obtained by solid reconstruction based on the tomography of the tooth used in the experimental test, which are analyzed by Finite Element Method (FEM). The global displacements are obtained from vertical ideal loading conditions. Experimental tests are performed using the same loads. The displacements are measured from a fiber Bragg grating (FBG) sensory system. Vertical compressive forces are applied to the tooth and the comparison between the displacements is performed. The differences between the results are evaluated and discussed in order to clarify how close the linear elastic simplified model approaches to the physical behavior of the tested orthodontic movement.
