ABSTRACT
However its mechanical and biological properties can be improved by the addition of bioactive materials, increasing its range of applications (Chuenjitkuntaworn et al. 2010 & Elzein et al. 2004). Eggshell (ES) is a natural biomaterial that reveals potential applications for bone regeneration owing to their biodegradability, good osteoconductivity, abundance and lower price (Ho et al. 2013). Its composition resembles mineralized bone matrix becoming a promising material for the synthesis of calcium enriched implants (Balaz et al. 2013, Ho et al. 2013 & Sariibrahimoglu et al. 2012), with considerable benefits to overall physiological function following implantation (Asghar et al. 2012, Ho et al. 2013 & Wu et al. 2013). Although the existence of many different possible biomaterials, composites made of different materials represent the optimal solution once they take advantage of specific properties of the constituents compounds (Abdal-hay et al. 2013 & Ni et al. 2014).
