“…Ceramics like hydroxyapatite (HA) have been used as bone substitutes, especially in human dentistry, as they are biocompatible, bioactive and osteoconductive, leading to bone regeneration in short periods of time (Borges et al, 2000;Fujibayashi et al, 2003;de Godoy et al, 2005;Lacerda et al, 2007;Sá et al, 2007). Direct contact with bone formed within its porous structure and biodegradation allowed bone tissue to develop and replace HA (Macneill et al, 1999;Borges et al, 2000;Rumpel et al, 2006).…”
