Some Mechanical Characteristics Of Materials For Dental Prosthetics
نویسندگان
چکیده
The paper presents some researches concerning the mechanical properties of composite materials used for prosthetic dental elements. After a short introduction concerning the general strains and loads that usually apply upon prosthetic works, the authors present the virtual model of a molar tooth subjected to the most common actions, using finite element method. Then the results are further shown by means of experimental methods and finally the conclusion concerning the possible use of fibre reinforced composite materials are presented.
