Resumo: | Yttria tetragonal zirconia polycrystal in the form of presintered commercial blocks is used to manufacture dental prostheses through computer-aided design/computer-aided manufacturing technology. Although it presents appropriate mechanical properties, it may fail because of defects resulting from the forming, presintering, machining, or sintering processes. The aim of the current study is to evaluate the influence of the presintering process on the microhardness of presintered blocks and on the elastic modulus of sintered materials. Blocks were formed by means of uniaxial and isostatic pressing. Next, they were presintered at different temperatures and soaking times, besides being subjected to the Vickers microhardness and mechanical tests to evaluate their elastic modulus. Statistical analyses showed that the presintering time at 900 degrees C had no effect on microhardness, although it was significant at 950 degrees C. The postsintering elastic modulus ranged from 205.7 to 231.9 GPa, which is similar to the range recorded in the literature. The presintering process had no influence on the postsintering mechanical resistance results. |
