Multivaruant Analysus of Stress-strain State of the First Upper Human Incisor wiht Post-and-Core Inlay

Nowadays, dentistry is actively developing due to the emergence of modern technologies, materials and new methods of dental treatment. With the help of different modeling systems various studies can be carried out and these studie allow to improve dental treatment. In these diploma project we consider the first person with an upper cutter pin copings. The aim of the study was to perform a biomechanical analysis of the use of different materials for the tab. To achieve this task we have applied the methods of mathematical modeling, finite element analysis of stress-strain state of the biomechanical system, the criterion of the maximum Mises stress. With the help of CAD SolidWorks 2016 features a model of the human upper jaw with the cutter was built containing the tab, and the crown. Also in this program the necessary calculations have been carried for the stress, we found a place of maximum stress. The work shows what materials are the best to use for the manufacture of a pin copings. Results of the study will help the dentist to make the right choice of material, which in dental prosthetics is a condition for the durability and strength of the structure, as well as a lower rate in the production.
