This research presents the technique of numerical calculations of mandible fractures, taking into account morphometric parameters. The received stress-deformed state of the mandible fragments, fastening plate and screws allows us to estimate the relative degree of displacement of the fragments and to evaluate their state after the action of chewing loads of phase 4.
The aim of the study – to analyze the behavior of the mandible fragments after fixing the angular mandible fracture with plates of different configurations using modern software complexes that implement the finite element method.
Materials and Methods. The behavior mandible fragments after fixing the plates of different configurations was the computer simulation in the ANSYS Workbrench software, namely, its module Transient Structural, which implements the method of finite elements.
Results and Discussion. After numerical calculations, it has been discovered that the use of computer technologies in maxillofacial surgery provides a more accurate picture of the treatment results, interaction and relative movement between parts of the system of "mandible fracture – plate – screws", which makes it possible to improve the treatment plan.
Conclusions. The use modern software complexes of automated geometric modeling allows us tocreate high-precision models o biomechanical systems based on CT data followed by finite-element sampling ad a numerical experiment in engineering analysis system.
