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...

Preparation and characterization of hydroxyapatite reinforced with hardystonite as a novel bio-nanocomposite for tissue engineering

Objecttive(s): Despite the poor mechanical properties of hydroxyapatite, its unique biological properties leads we think about study on improving its properties rather than completely replacing it with other biomaterials. Accordingly, in this study we introduced hydroxyapatite reinforced with hardystonite as a novel bio-nanocompositeand evaluate its in-vitro bioactivity with the aim of developi...

Tailored Surface Treatment of 3D Printed Porous Ti6Al4V by Microarc Oxidation for Enhanced Osseointegration via Optimized Bone In-Growth Patterns and Interlocked Bone/Implant Interface.

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...
