Mathematical analysis of computer modeling of adhesive structures
Abstract
Abstract. Stress analysis results of dental prosthesis fiber adhesive structures with the use of final element method is discussed in the article. Computer models of dental prosthesis with different reinforcing frame layouts were developed. Reinforcing fiber positioning impact on appearance and distribution of tensile and equivalent (von Mises) stresses in prosthesis structure was analyzed. It has been established that the arrangement of two reinforcing fibers in mutually perpendicular planes under the action of both vertical and combined loads makes it possible to reduce the mechanical stresses in the most loaded zones of the AVK material to 20% compared with the use of one fiber frame with its different spatial orientation and up to 6,3% compared to using two lengths of fiber located in a vertical plane. Carried out analysis made possible to find out and substantiate rational reinforcing fiber frame layout for prosthesis adhesive structure providing stress reduction.
