Hydroxyapatite (HA) has been widely investigated as scaffolding material for bone tissue engineering, mainly for its excellent biocompatibility. Presently, there is an increasing interest in the composites of hydroxyapatite with bioactive glasses, with the aim to obtain systems with improved bioactivity or mechanical properties. Moreover, modifying the ratio between bioactive glass and hydroxya...

PURPOSE To evaluate the clinical outcome of implants placed into sites grafted with bioactive glass. MATERIALS AND METHODS Seventeen consecutively treated patients were referred to a private specialist surgical practice for the repair of dentoalveolar defects, and/or ridge maintenance at the site of extraction sockets, prior to implantation. Bioactive glass available in 1 of 2 forms was utili...

Bioactive glasses are promising materials for bone scaffolds due to their ability to assist in tissue regeneration. When implanted in vivo, bioactive glasses can convert to hydroxyapatite, the main mineral constituent of human bone and form a strong bond with the surrounding tissues thus providing an advantage over polymer scaffold materials. Bone scaffold fabrication using additive manufacturi...

Poly(glycerol sebacate) (PGS) is an elastomeric polymer which is attracting increasing interest for biomedical applications, including cartilage regeneration. However, its limited mechanical properties and possible negative effects of its degradation byproducts restrict PGS for in vivo application. In this study, a novel PGS-bioactive glass fiber (F18)-reinforced composite was developed and cha...

This paper will report on research which aims to generate bone replacement components by processing bioactive glass-ceramic powders using indirect selective laser sintering. The indirect SLS route has been chosen as it offers the ability to tailor the shape of the implant to the implantation site, and two bioactive glass ceramic materials have been processed through this route: apatite-mullite ...

We investigated the interwire distance dependence on the growth kinetics of vertical, high-yield InAs nanowire arrays on Si 111 grown by catalyst-free selective area molecular beam epitaxy MBE . Utilizing lithographically defined SiO2 nanomasks on Si 111 with regular hole patterns, catalyst-free and site-selective growth of vertically 111 -oriented InAs nanowires was achieved with very high yie...
