Biologic properties of nano-hydroxyapatite: An in vivo study of calvarial defects, ectopic bone formation and bone implantation

This study investigated the biologic properties of nano-hydroxyapatite (nHAp) using the rat calvarial defect, ectopic bone formation, and rabbit tibia implant installation models. Animals were divided into two groups: those implanted with nHAp, and n
