A 3-dimensional finite element model of mandible anterior section, including a segment of mandibular bone tissue, four incisors, periodontal ligament (PDL), polymethylmethacrylate (PMMA) immobilizing splint of 0.5 mm thickness was developed. The stress-strain state of the model components is considered for the cases of a splinting structure presence and absence from the action of a typical occlusal load F = 200 N. The influence of the physicomechanical properties determining method for mandible bone tissue on the obtained results is evaluated.
