Professor Larry Hench will receive the Acta Biomaterialia Gold Medal at the annual meeting of the European Society for Biomaterials in Liverpool on Sept 3, 2014. This is an excellent opportunity to honor his pioneering work in biomaterials through the publication of a virtual issue on bioactive glasses.

The 29 articles published recently in Acta Biomaterialia are a showcase of the diversity and breadth of this research topic [1-29]. Besides the traditional use of bioactive glasses to improve the biological properties of biomaterials, new research domains have emerged. For example, attempts have been made to produce 3D scaffolds and to define the most adequate architecture. Also, elements that are not traditionally used in bioactive glasses (Ag, B, Ce, Co, F, Ga, Si, Sr, Zn) have been added to confer new or improved properties. This follows Larry Hench’s concept of “Third Generation Biomedical Material” according to which a biomaterial should combine resorbability and bioactivity.

Two review articles are included in the virtual issue. Goudouri et al. discuss the “Antibacterial properties of metal and metalloid ions in chronic periodontitis and peri-implantitis therapy”. Even though this review article is not only devoted to bioactive glasses, it is focused on a growing research and commercial area for bioactive glasses. The second review, written by Julian Jones, one of the past Ph.D. students of Larry Hench, has become within a year THE review paper on bioactive glasses. Its title says it all: “From Hench to hybrids”.
