Abstract

Natural hydroxyapatite (HA) is the main component of bone. HA and biphasic composites (HA and b−tricalcium phosphate) are in fact the most common bioceramics used for bone regeneration.Natural hydroxyapatite (HA) is the main component of bone. HA and biphasic composites (HA and b−tricalcium phosphate) are in fact the most common bioceramics used for bone regeneration. To confirm the effect of polarization, cell culture assays were made using human osteoblasts (responsible for bone growth). Both non-polarized and polarized control samples were used. After 2 weeks, dried samples were gold coated and then cell morphology was evaluated by SEM. Iit is possible to observe osteoblasts deposited on HA surfaces. Polarized samples showed more osteoblasts and higher deposition of calcium phosphates.
