Evaluation of magnesium-based scaffolds fabricated using a modified sintering technique and two types of space holding agents (in vitro study).

ABSTRACT:

Objective

The aim of this work was to study the mechanical, degradation behavior and bioactivity of porous magnesium-based scaffolds alloyed with zinc and hydroxyapatite, fabricated using two different types of space holding agents and a modified powder metallurgy route.

Methods

Powder particles of magnesium, zinc, hydroxyapatite (HA) and spacers were mixed, then mixtures were divided into 6 groups: IA (urea/0%HA), IB (urea/5%HA), IC (urea/7.5%HA), IIA (ammonium bicarbonate/0%HA), IIB (ammonium bicarbonate/5%HA) and IIC (ammonium bicarbonate/7.5%HA). A modified powder metallurgy route was used to fabricate the composites.
