The research results of the damaging effect of the load, equivalent to 50 and 200 kg, on the frontal wall of maxillary sinus are presented. According to this goal, 3D-model of maxillary sinus was built using SCT-data. Finite element method (FEM) was used to simulate the reaction of bone tissue to burden. Two parameters characterized the reaction: value and square of stress and displacement. Characteristic of strain value, area and reversibility depending on the load degree is given. Areas of destruction and areas of risk for each variant of load are defined. The relation of the load degree and it’s effect are obtained: with the load equivalent to 50 kg bone tissue of the anterior wall of maxillary sinus around the area of the defect does not lose its plastic properties, any changes are reversible. The load equivalent to 200 kg results in such irreversible changes of bone which cause destruction and cracks.

Key words: maxillary sinus, 3D-model, finite element method, trauma.
