The biomaterials for medical applications includes synthetic and natural
polymers. Biomaterials inspired in the bone composition are used as excellent
alternative for their substitution [1]. The bone composition is characterized for
their inorganic bone components that are between 60% and 70% of the bone
weight. They include calcium phosphate, sulfates and other minerals, Mg, Na,
Zn, and K as minor elements. The organic phase is constituted mainly by
collagen protein. In the present study, were used material elaborated based in
the natural bone composition. The objective of this study was to assess the
properties of a polymeric material added with an inorganic mixture of elements
to simulate the bone composition, which has the potential to be used for
replacing the damaged bone tissue. The standardized samples were elaborated
[2] using a mixture of casein, minerals mixture, polymethylmethacrylate,
monomer and silver particles. The mechanical properties were studied using
flexural tests. Morphology and microstructure analysis were done using the
scanning electronic microscope, X-Ray diffraction and infrared spectroscopy,
respectively. The material showed similar properties to bone tissues, making
them attractive for the design of biomimetic materials [3].
