Amorphous Calcium Phosphate Layer Prepared Ultrasonically on Titanium

Popis výsledku v původním jazyce

An inert titanium surface was treated with the so-called BIO treatment (developed by the company Lasak, s.r.o.), i.e. its surface area was increased by mechanical and chemical treatment with blasting and exposure to HCl and NaOH. The treated surface wasprovided with thin layers of calcium phosphate OCP (octacalcium phosphate) or ACP (amorphous calcium phosphate) by means of precalcification under static conditions (using an supersaturated SCS2 solution). In vitro tests in SBF (Simulated Body Fluid) under dynamic conditions have shown that precalcified OCP layers have the ability to induce development of HAp (hydroxyapatite) on the surface much faster than BIO surfaces without such layers. OCP crystals develop during 24 hours of precalcification (understatic conditions in SCS2 (Supersaturated Calcifying Solution) and they are up to 20 ?m thick. The layers are well adhesive but cytotoxicity tests have shown that a bioactive layer prepared in this manner is slightly toxic. Therefore a v
