Different titanium surface treatment influences human mandibular osteoblast response
The trial was carried out to observe using an electronic microscope the osseointegration ability of 6 different treatments applied to as many titanium discs using osteoblasts (machined SS titanium, plasma spray TPS titanium, corundum C100 sandblasted + acid treatment, corundum C150 sandblasted + acid treatment, zirconium dioxide B60 sandblasted + acid treatment, zirconium dioxide B120 sandblasted + acid treatment).
The trial recorded drastic differences relative to cell density: the sandblasting + acid treatment samples are those featuring the highest cell density and adhesion in comparison with smooth titanium and TPS.As regards those with the higher density, the best treatments appear to be B60 and B120.The trial also confirms that corundum sandblasting must be combined with acid treatment to prevent (potentially toxic) treatment micro residues (alumina).
