Progress of three-dimensional macroporous bioactive glass for bone regeneration

Lijun JI, Yunfeng SI, Ailing LI, Wenjun WANG, Dong QIU, Aiping ZHU

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 4,   Pages 470-483 doi: 10.1007/s11705-012-1217-1

Abstract: Bioactive glasses (BGs) are ideal materials for macroporous scaffolds due to their excellent osteoconductive, osteoinductive, biocompatible and biodegradable properties, and their high bone bonding rates. Macroporous scaffolds made from BGs are in high demand for bone regeneration because they can stimulate vascularized bone ingrowth and they enhance bonding between scaffolds and surrounding tissues. Engineering BG/biopolymers (BP) composites or hybrids may be a good way to prepare macroporous scaffolds with excellent properties. This paper summarizes the progress in the past few years in preparing three-dimensional macroporous BG and BG/BP scaffolds for bone regeneration. Since the brittleness of BGs is a major problem in developing macroporous scaffolds and this limits their use in load bearing applications, the mechanical properties of macroporous scaffolds are particularly emphasized in this review.
