Computational Model of a Skeletal Dental Prosthesis´s Mechanic Work

Computation of the stress pattern (deformations) and displacements of the dental prosthesis required a spatial representation of the systems´ work during the chewing process. The aim was to formulate a numerical model that would facilitate optimalisation of the occlusion loads´ distribution in prosthesis´s shape function. Discretization of the prosthesis thin metal coating that covers the tissues was made with the help of the 3D digital system MicrScribe G2X (immersion) and a computer programme created for that. It facilitated generating an ordered system of flat elements of a finite number of nodes on the basis of the points dispersed on the diagnostic gypsum ground´s model.
