Evaluating the efficacy of eggshell-derived hydroxyapatite (EHA) and synthetic hydroxyapatite (SHA) in bone regeneration of maxillofacial defects-a randomized double-blind pilot comparative clinical-radiological study

Both EHA and SHA graft materials are equally efficient in early bone regeneration. The EHA showed promising results and enhanced bone regeneration with osteoconductivity, which indicates the eggshell waste-bio mineral is worthwhile raw material for the production of HA and is Go Green procedure. EHA is economic, compared with SHA.
