Dental implants made of titanium may provide long-term stability and occlusion like real ones. According to late researches, the roughness, size of surface structuring and chemical properties is significantly effective for protein adhesion, which is beneficial to the apposition between osteoblast to the implants. Good osseointegration may reduce inflammation after surgery and avoid the chances to failure. Nano-scale structurization on implant surface was achieved via femtosecond surface treatment. Properties of surface are the key factor with osseointegration in this study. In this experiments treatment on titanium substrate within areas are carried out via femtosecond laser and need to be investigated. From analysis by SEM and AFM the surface morphology are obtained with different treatment by various pulse numbers and roughness increased with the pulse numbers. From XRD analysis it is clear that substrate surface formed titanium monoxide when applied pulses were higher than 100. Contact angle measurement of surfaces treated by various pulses showed that the change of surface morphology provided improvement on wettability of treated surfaces.
