Used as a biocompatible substrate in bone regeneration studies and dental research due to its similarity to natural bone mineral. Commonly employed in in vitro testing of cell growth, adhesion, and differentiation, especially with osteoblasts. Its porous structure supports mineral deposition and makes it suitable for drug delivery system evaluations. Frequently used in implant coating development and biomaterials testing where a calcium phosphate base is required. The defined circular shape and size allow for standardized testing in multi-well plates and histological analysis.
