ABSTRACT
The objective of this research was to study the agespecific features of maxillary sinus anterior wall bone tissue response to the increasing traumatic load. For this purpose the authors used the data of 143 series of spiral computer-aided tomography (SCAT). The data of patients that belonged to 3 age groups: 2040 years old, 4160 years old and 61 years old and older were used for the study. Based on the tomographic images the authors made the corresponding 3D models using “Rhino” web application. The obtained models were used for finite element method (FEM) calculations that allowed for agespecific mechanical properties of bone tissue. The authors calculated the stress-deformed states under the defined load equivalent to 50 and 200 kg (the impact during the operation and trauma respectively), affecting in the area of fossa canina. The modelling was made using “Solid Works 2012” software. The study result has revealed that despite the age-related bone tissue elasticity loss it retains its capacity of resisting the irreversible deformation under the load of 50 kg. This area elasticity loss is observed as early as after the age of 40, it manifests itself in the increase of the stress to the displacement ratio. With aging, the load increase to 200 kg produces fast and extensive destruction of the bone tissue of maxillary sinus anterior wall. It spreads in uppermedial direction. After the age of 60, the same load also produced destruction at the point of direct effect of the traumatic force, in the upper-medial direction from it and along the periphery. It can manifest itself in generation of micro- and macro-fracture of these areas.
