Avaliação físico-química de membranas de implantes mamários comercializados no Brasil.

Abstract

This work aims to evaluate silicon membranes surrounding the breast implant filled with silicone gel, in order to verify the conformity of its properties. As a strategy, we used the characterization techniques to analyze the physicochemical parameters in three different batches of breast implant. The experimental results were compared with values referenced in standard or standards established in the literature. Thus, it was possible to analyze some attributes that influence the quality of these implants. The results of OM and SEM microscopy did not detect anomalies in the surfaces of the samples. Were detected by testing the EDS spectra of carbon, silicon and oxygen elements, also identified as metals iron, calcium, nickel and chromium in the test samples. The stretching test two samples did not meet the regulatory requirement. Therefore, it is concluded that the integrity of the silicone membranes was compromised, because its mechanical behavior, in two of the three samples tested.
