Bone ingrowth is defined as the growth of new bone cells on the irregular surface of an object.  It is often referred to in the context of grafting new bone growth on a surgical or dental implant in the human body.  Titanium implants, for example, are used to replace or supplement bone or teeth in the body.  The irregular surface of the titanium implant allows for bone ingrowth in the early stages.  Initially, blood proteins coagulate onto the implant surface, allowing osteoblasts to attach themselves.  Osteoblasts are special cells that produce new bone cells.  They allow for bone growth and for bone repair.  The osteoblasts then produce new bone material around the implant, thus incorporating it into the existing bone.
