CHOOSING THE OPTIMAL METHOD OF DENTAL IMPLANTATION FOR ATROPHIED JAWS

Abstract

The article provides information about the study on choosinh the optimal method of dental implantation for atrophied upper jaws. Using the final elemental analysis method (FEM), the level of bone stress around dental implants of various lengths and installed at various angles according to the “All-on-Six” concept was assessed. CT images were used to create a geometric model of the upper jaw. Using the “3DDoctor” and “3D Complex Render” programs, a 3D model of the bone tissue of the upper jaw was created. The occlusal pressure of 300 Newton was applied perpendicular to the foodstaff with a diameter of 1 cm, which was located between the 2nd premolar and the 1st molar on the left. The study showed that when placing dental implants at an angle of 15º, stress levels in the cortical bone were reduced by 35%, and at 25º by 50%. As a result, we can draw the following conclusion: when using the “All-on-Six” concept for dental implantation in the posterior parts of the upper jaw, installing implants at an angle is more appropriate than installing short implants.
