Abstract:

BACKGROUND: Compared with the titanium with smooth surface, TiO2 nanotubes are more beneficial for the early cell adhesion.
OBJECTIVE: To review the research progress of the effect of TiO2 nanotubes on peri-implant cells.
METHODS: A computer-based retrieval of CNKI, CqVip, WanFang and PubMed databases was performed for pertinent literatures published between 1990 to 2016, using the Chinese keywords of “TiO2 nanotubes or titanium dioxide nanotubes and implant”, and English keywords of “TiO2 nanotubes implant, Tio2 nanotubes cell”.
RESULTS AND CONCLUSION: The main factors that TiO2 nanotubes affect the peri-implant cell behaviors include the tubular morphology, size, TiO2 crystal structure, as well as surface chemical compositions, roughness and hydrophilicity and free energy. The influence factors of TiO2 nanotubes for cells are not only related to the tube diameter, but also associated with cell types. Different cell types hold different diameters suitable for the cell adhesion, proliferation and differentiation on the material surface. Therefore, it is advisable to select the best nanotube size for different tissues and cells applied in different biomedical fields.
