摘要: Abstract Titanium (Ti) osseointegration is critical for the success of dental implants. Previous studies have shown that wettability controls are great importance their biomedical application. Only relatively recently effects a plasma oxidized surface on cell response been considered. The aim present study was to develop simple and scalable modification treatment introduces oxidation method surfaces Ti substrates without changing original morphologies other features. controlled micro/nano-structure achieved by using sandblast-acid etching (SLA) process. Then, titanium oxide SLA base radio frequency enhanced chemical vapor deposition (RF-PECVD) system, while retaining starting micro/nano-texture topography. water contact angles (CA) these increase then decrease with self-bias voltage. A superhydrophilic TiO 2 (anatase) can be when voltage 360 V. Such showed crystal structure an anatase (101) orientation possessed elemental compositions , O 3 TiO. MG63 cells were seeded disks. results suggested introduction such in combination micro/nano-structures improves osteoblast attaching spreading, which, turn, indicates potential improved implant vivo.
