Characterization of a Novel Porous Titanium Scaffold for Orthopedic Applications
ثبت نشده
چکیده
INTRODUCTION: Highly porous metals, such as porous titanium and tantalum, have been developed for use in orthopedics. Ideal porous materials should have a porosity greater than 60% with interconnected pores of 100-500 μm for osseointegration and match the mechanical properties of bone [1]. With improved osseointegration and similar properties to bone, instances of implant stress shielding and failure can be minimized [2]. Many of the currently available porous metals do not meet the desired design criteria and have high manufacturing costs [3]. The purpose of this study was to design a cost effective load bearing porous titanium scaffold with tunable mechanical properties. The scaffold must also have a biomimetic pore structure for optimal tissue ingrowth and strong fixation.

Synthesis and Characterization of Highly Porous TiO2 Scaffolds for Bone Defects
The purpose of this study was to fabricate and investigate the highly porous structure using titanium dioxide, which is a candidate for bone defect repairing. For this purpose, TiO2 scaffolds were synthesized using titanium butoxide, Pluronic F127 surfactant, and polyurethane foam blocks. Therefore, a colloid includes titanium butoxide and F127 and the polyurethane foams were immersed in it. Th...

3D printed porous titanium (Ti) holds enormous potential for load-bearing orthopedic applications. Although the 3D printing technique has good control over the macro-sturctures of porous Ti, the surface properties that affect tissue response are beyond its control, adding the need for tailored surface treatment to improve its osseointegration capacity. Here, the one step microarc oxidation (MAO...
