“…Several studies have also shown that hydrophilic surfaces are necessary for biomaterial tissue integration. 15 Other recent studies have shown that the size and characteristics of the features may be more important than the effects of chemical composition alone. 17 Therefore, nanoscale features play an important role in osteogenic differentiation.…”

“…[3][4][5][6] Many studies have focused on the osseointegration process, and it is now described at both the histological and cellular levels. Previous work has shown that surface characteristics such as roughness, [7][8][9] wettability, [10][11][12][13][14] and surface structures [15][16][17] significantly influence cell differentiation and, as a consequence, osseointegration. 16,18 Bone marrow mesenchymal stem cells (BMMSCs) are multipotent stem cells and represent a particularly attractive source for tissue engineering.…”

“…19,20 There are numerous ways that the implant surface can be modified to have nanoscale features added to these surfaces in combination. The most common are chemical processes such as alkaline hydrothermal 20,24,25 or acid 6,15,17,22 oxidation on titanium surfaces to create different nanoscale topographies. Among the common surface nanotopographies, the titania nanotube has drawn much attention.…”

Background Titanium surfaces play an important role in affecting osseointegration of dental implants. Previous studies have shown that the titania nanotube promotes osseointegration by enhancing osteogenic differentiation. Only relatively recently have the effects of titanium surfaces with other nanostructures on osteogenic differentiation been investigated. Methods In this study, we used NaOH solutions with concentrations of 2.5, 5.0, 7.5, 10.0, and 12.5 M to develop a simple and useful titanium surface modification that introduces the nanonetwork structures with titania nanosheet (TNS) nanofeatures to the surface of titanium disks. The effects of such a modified nanonetwork structure, with different alkaline concentrations on the osteogenic differentiation of rat bone marrow mesenchymal stem cells (BMMSCs), were evaluated. Results The nanonetwork structures with TNS nanofeatures induced by alkali etching markedly enhanced BMMSC functions of cell adhesion and osteogenesis-related gene expression, and other cell behaviors such as proliferation, alkaline phosphatase activity, extracellular matrix deposition, and mineralization were also significantly increased. These effects were most pronounced when the concentration of NaOH was 10.0 M. Conclusion The results suggest that nanonetwork structures with TNS nanofeatures improved BMMSC proliferation and induced BMMSC osteogenic differentiation. In addition, the surfaces formed with 10.0 M NaOH suggest the potential to improve the clinical performance of dental implants.

“…One of the most widely used processes is introducing different chemical and/or biochemical substances on the surface. Such modifications of the atomic composition of the surface have led to significant improvements in the cell response on the surface material both in vitro and in vivo [10][11][12][13] . Impregnation or coating with hydroxyapatite 14,15) or calcium phosphate 16,17) have been proposed as biomimetic approaches.…”

“…Titanium surfaces with nanostructures show better cell migration and differentiation in vitro 5,6) and improved osteointegration in vivo compared with the traditional titanium surface without nanostructures 7) . Several methods can be utilized to modify titanium surfaces and produce nanostructures, such as alkaline hydrothermal 8,9) or acid oxidation 10,11) . Our previous studies have demonstrated that treatment with high concentrations of alkali can produce a basic, hydrophilic sodium titanate layer with nanonetwork structures on the titanium surface, termed titanium with nanonetwork structures (TNS) 12) .…”
