Bone matrix consists of organic and inorganic components. Organic phase mainly
contributes to flexibility of bone while inorganic phase being responsible for the rigidity and
hardness of the bone. Due to the biocompatibility of ceramics many forms of them have been used
as the bone replacement and as the repair material. Hydroxyapatite which also exists in the natural
structure of bone is one of those ceramics used as a component of bone cement. In order to modify
the physical properties of prepared bone composite structures, some additives are included within
the structure. In this study, a silicate material is included as an inorganic filler together with
hydroxyapatite. Bis-GMA and HEMA were used as organic matrix. The prepared composites were
than immersed in SBF and FTIR, SEM, hardness analyses were performed on the samples before
and after the immersion. The results were reported in later part. It was observed that the
precipitation of hydroxyapatite occurred after the immersion of samples in SBF and the hardness
values were increased for each sample
