Abstract

AISI 316L stainless steel is biocompatible and considered in the manufacturing of dental and orthopedic implants. However, literature has reported infections in implanted metallic component, which is associated to bacterial biofilm formated on the implant surfaces. To inibith this problem, alternatives to improve the metal surface properties have been researched, including techniques for chemical and topography changes of metal surfaces, since bioadhesion is influenced by the hydrophilicity of the material. The objective of the research is to produce LIPSS using nanosecond Nd:YAG laser on the surfaces of AISI 316L, evaluting the influence of superficial changes in the growth and adhesion of bacterial biofilm in the modified region. It is expect to obtain parameters for the establishment of a process with a maturity degree to future applications in biomedical components, such as prostheses dental and/or orthopedic.
