Abstract

The aim: To create a three-dimensional simulation mechanical-mathematical model of the biomechanical system “Orthodontic appliance-maxilla”, to study peculiarities of the stress-strained state of the maxilla. Materials and methods: A simulation model of the biomechanical system “Orthodontic appliance-maxilla” was created using computed tomography (CBCT) data. Mathematical modeling was used to determine the stress-strain state of the simulation model. Results: The patterns of changes in the stress state were determined and the values of deformation displacements in the structural elements of the biome¬chanical system “Orthodontic appliance-maxilla” were determined under a force stress of the orthodontic device with an amplitude of 50 N. Conclusions: Simulation computer modeling of the stress-strain state of the “Orthodontic appliance-maxilla” system showed that activation of the kinematic mechanism of the appliance with a force of 50 N causes the emergence of a complex stress-strain state of bones. When the orthodontic appliance is activated, there is an asymmetry in the distribution of stresses by Mises between the right and left sides both for the appliance itself and for the maxillary bone tissue.
