Effect of micro-arc oxidation surface modification of 3D-printed porous titanium alloys on biological properties.

ABSTRACT:

Background

Three-dimensional (3D) printing technology has been widely used in orthopedics; however, it is still limited to the change of macroscopic structures. In order to further improve the biological properties of 3D-printed porous titanium scaffolds, this study introduced micro-arc oxidation (MAO) technology to modify the surface of porous titanium scaffolds and construct bioactive coatings on the surface of porous titanium scaffolds to improve the biocompatibility and osseointegration ability of the material.

Methods

For in vitro experiments, human bone marrow stem cells (hBMSCs) were seeded onto untreated scaffolds (control group) and MAO-treated scaffolds (experimental group). After 24 h of co-culture, cytotoxicity was observed using live/dead staining, and ce
