The Determination of the Elasticity Constants of the Materials for Removable Partial Dentures
Abstract
The knowledge of the elastic characteristic of the constituting materials of the dentures is necessary in the calculation of strength, strains and stability, in the experimental stress analysis and in the finite element method usage. Purpose the study establishes the material constants: the coefficients of elasticity and Poisson coefficients. Materials: we used 4 specimens from specific biomaterials of removable denture. Materials and method The four specimens were tested to determine the tensile strength using the Instron testing machine. Results The material constants determination is necessary in biomechanical behaviour of removable dentures analyses. Conclusion The models can be considered linear elastic bodies
