Surface State Studies and Biocompatibility of PMMA

Abstract:

In this work we accomplished a study concerning the surface state of acrylic prosthetic biomaterials both optimized and non-optimized and we studied their compatibility on test animals. Various methods are seeking to improve the quality of implants and minimally invasive devices for body analysis, the increase of biocompatibility and resistance to corrosion of materials intended to come into contact with biological tissues. Poly (methyl methacrylate) is used in a wide range of applications and offers increased resistance and color stability over time and it can be relatively easy to smooth and polish. The morphology and roughness of the surfaces in case of acrylic prosthetic biomaterials were analyzed by atomic force microscopy that provides qualitative information regarding the chemical uniformity from phase.
