Abstract Scope |
With the rapid advancement in ceramic technology, several research efforts have been devoted to developing alumina (Al2O3) based composites with better mechanical and tribology properties for orthopedic applications. Calcium titanate (CaTiO3), which has dielectric properties like that of bone, can be incorporated to enhance the electrical conductivity and bioactivity of Al2O3. This study employed a conventional pressureless sintering technique to fabricate Al2O3-CaTiO3 nanocomposites produced by the sol-gel process. XRD and SEM analysis showed better morphology and retention of Al2O3 and CaTiO3 phases. In-vitro studies inferred that adding CaTiO3 to Al2O3 promotes myoblast adhesion and growth compared to Al2O3. Impedance analysis obtained with increasing CaTiO3 content can be correlated to the increased conductivity of the Al2O3. Finally, it can be hypothesized that the electrical conductivity of Al2O3-CaTiO3 bioceramics facilitates the orientation and fusion of myoblast, even without subjecting it to any external electrical stimulation. |
