Enhanced Adhesion of Human Osteoblast-Like Cells on Femtosecond Laser Treated Ti-6Al-4V

Abstract:

Several techniques of implant surface structuring have been used in the past to modify the surface of titanium and its alloys. We first investigated the adhesion property of human osteoblasts (MG-63) on femtosecond laser treated Ti-6Al-4V for application in dental implant. Two different kinds of surface structures were generated with varied laser fluence. (1) Laser-induced periodic surface structures (LIPSS) with a period on the sub-micron level. (2) Microscale peaks and troughs surface structures (MPTSS) with superimposed submicron and nanoscale features. According to the cell quantity and adhesion property of MG-63 on polished and structured samples, femtosecond laser treated Ti-6Al-4V with LIPSS may more suitable for applied in dental implant.
