Abstract
A biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material having a sintered CAP core and a closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core, wherein the closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core has a homogeneous coarse external surface comprising flat crystal platelets, which shows an enhanced osteogenic response, a method of promoting bone formation, bone regeneration and/or bone repair by implanting the biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material, and a process of preparation thereof.
Claims19
A biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material comprising a sintered CAP core and a closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core, whereby the epitactically grown nanocrystals have the same size and morphology as human bone mineral, wherein the closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core has a homogeneous coarse external surface comprising flat crystal platelets, and wherein the homogenous coarse external surface comprises epitactically grown nanocrystalline hydroxyapatite platelets forming an interlocked network of platelets with sizes of 0.2 to 20 μm as determined by Scanning Electron Microscopy (SEM).
