Biological Performance

Lime phosphosilicate and soda lime phosphosilicate glasses prepared by sol-gel method were precursors of bioactive glass-ceramics. The structure of the samples and the distribution of the [SiO4] units was investigated by X-ray diffraction and infrared spectroscopy. Human osteosarcoma cell line (MG63) was used for the in vitro cellular response. DNA staining (Hoechst 33258) assay was performed for assessing samples colonization.

Bioactive Glasses

In the last years, bioactive glasses and glass-ceramics drew the attention for their application in the production of implants. Among them, Bioglass®45S5 is the most commonly used in terms of bioactivity, but its sintering behavior and the related glass-ceramics strongly depend on the followed synthesis process. For these reasons, this paper reports a comparison of the properties and the thermal behavior of bioactive 45S5 glasses produced by a conventional melting process starting from suitable solid precursors or an innovative sol-gel procedure.

Carrier Systems

The application of bioactive glass and glass-ceramics has been widely documented over the past twenty years but the high modulus and low fracture toughness has made them less applicable for clinical, load bearing, applications. The development of non-resorbable polyethylene and poly-sulphone matrices for these materials has improved the mechanical properties. However, the primary concern of whether the bioactivity of the composites is reduced is still unresolved. The more recent development of resorbable carrier systems, dextran and collagen, for bioactive glasses does not introduce such problems, hence making this form of composite suitable for novel soft tissue applications. The development of a simple quality index has enabled some of the materials described within this paper to be ranked by their ability to replace bone, thus enabling possible new research directions to be emphasized.

New Generation

Glasses are common in use now days. These are used in different applications like domestic, automobile, telecommunication etc. The glasses are very useful materials because of their impressive properties. Few years back a new generation of glasses were developed i.e. bioactive glasses and bioactive glass ceramics. The glasses are used for bone grafting now-a-days because of their impressive bioactive properties. These glasses have tendency to form bonds with the living tissue organs. The future of these glasses will be bright in dental, orthopedics and prosthetic applications. In the present work borosilicate glasses of different compositions have been studied. The different elements were added with appropriate mol% to compose a new bioglass composition. The samples were prepared by melt quench route. The samples were immersed for 21 days in SBF. The samples were characterized before and after immersion in SBF by different techniques. The XRD technique was done to confirm the amorphous nature of glass before immersion and after immersion. The SEM and EDX were done to check the changes on the surface after immersion. The sample S1 has better biocompatibility results than S2 andS3. The formation of apatite on the glass samples were confirmed by all techniques mentioned above.

In this paper, three ceramic compositions 50SiO2-50CaO (A), 45SiO2-45CaO-10P2O5 (B) and 40SiO2-40CaO-20P2O5 (C) (wt %) were synthesized by using the sol-gel technique. XRD analysis demonstrates that only sample C can form the glass material. Treated temperatures and heated times were also evaluated. Analysis data showed that the bioglass 40SiO2-40CaO-20P2O5 (wt %) can successfully elaborate when the ceramic powder heated at 750 oC for 3 hours. ‘‘In vitro’’ experiment was effectuated to investigate the bioactivity of bioglass 40SiO2-40CaO-20P2O5 by soaking powder samples in SBF solution. Obtained result confirmed the formation of hydroxyapatite (HA) phase on glass’s surface after 15 days of immersion, in which HA formation orients following (211) and (222) miller planes in crystalline structure of HA phase.
