Synopsis
Surface wettability is important for obtaining osseointegration. Recently, the authors have applied various plasma treatments to pure titanium surfaces as a method of achieving superhydrophilicity, and found that these surfaces contributed to the initial adhesion of rat bone marrow cells and the ability to induce differentiation of hard tissues. The results suggest that the use of argon gas has a greater effect on the ability to induce hard tissue differentiation than the use of atmospheric pressure plasma alone. On the other hand, it has been reported that increasing the output of argon gas can have a greater effect. Therefore, we compared the effects of argon plasma treatments with different outputs on rat bone marrow mesenchymal cells. The results of this study showed that argon plasma treatment with higher output power had a higher ability to induce hard tissue differentiation in pure titanium.
