Definição de propriedades mecânicas de biomateriais e materiais biológicos utilizados em odontologia via indentação instrumentada

Abstract

This research sought to measure and define mechanical properties of hardness, elastic modulus and the material constant by using samples of biological, ceramic and metallic biomaterials, such as alloy Ti6Al4V, feldspathic porcelain, lithium desilicated porcelain and human molars teeth, by means of instrumented indentation. For each sample, two loads (1,0N and 0,5N) were used to make three to five indentations. After the instrumented indentation tests, it was found that brittle materials have a better response to the method, despite some fractures were recorded with the penetration, while the Ti6Al4V alloy did not provide an appropriate response. The difference in behavior is associate with systemic errors that could not be removed to carry out this search.
