Description
SigmaGraft Biomaterials provides ceramic particles such as hydroxyapatite (HAp), beta-tricalcium phosphate (β-TCP), and biphasic calcium phosphate (BCP) for an application of various bone graft substitute or other medical implant applications. Custom sizes available upon request.
Hydroxyapatite (HAp)
Hydroxyapatite (HAp) is a calcium phosphate similar to the human hard tissues in morphology and composition. The chemical formula of HAp is Ca5(PO4)3(OH). Particularly, it has a hexagonal crystal structure and a Ca/P ratio of 1.67 that is identical to human bone. HAp is the most stable calcium phosphate with low solubility in physiological environments defined by temperature, pH, body fluids, etc.
*Synonyms: Calcium phosphate tribasic, calcium hydroxyapatite
Beta-tricalcium phosphate (β-TCP)
β-TCP is a biodegradable bioceramic with the chemical formula Ca3(PO4)2 with a Ca/P ratio of 1.5. β-TCP has a faster degradation rate and higher solubility than hydroxyapatite. It has a high resorption rate and is widely used to increase biocompatibility.
Biphasic calcium phosphate (BCP)
BCP generally combine two more incompatible calcium phosphates, such as the more stable HAp and the more soluble β-TCP with different compositions. BCP have been used as bone grafts, bone substitute materials, and dental materials. The mixture of HAp and β-TCP can be used to stimulate the osteogenic differentiation, increase cell adhesion, and enhance mechanical properties.
