The use of bone scaffolds to replace injured or diseased bone has many advantages over the currently used autologous and allogeneic options in clinical practice. This systematic review evaluates the current evidence for non-cellular scaffolds containing bioactive glass on osteogenesis and angiogenesis in animal bone defect models. Studies that reported results of osteogenesis via micro-CT and results of angiogenesis via Microfil perfusion or immunohistochemistry were included in the review. A literature search of PubMed, EMBASE and Scopus was carried out in November 2019 from which nine studies met the inclusion and exclusion criteria. Despite the significant heterogeneity in the composition of the scaffolds used in each study, it could be concluded that scaffolds containing bioactive glass improve bone regeneration in these models, both by osteogenic and angiogenic measures. Incorporation of additional elements into the glass network, using additives, and using biochemical factors generally had a beneficial effect. Comparing the different compositions of non-cellular bioactive glass containing scaffolds is however difficult due to the heterogeneity in bioactive glass compositions, fabrication methods and biochemical additives used.

Immune cells, such as macrophages, stimulated by several types of inorganic ions released from bioactive glasses secrete cytokines that promote and inhibit bone formation. In this study, the effects of borate-ion-stimulated mouse macrophages (RAW264) on the osteogenic differentiation of mouse bone marrow-derived mesenchymal stem cells (KUSA-A1) are investigated. KUSA-A1 is cultured with a borate-ion-containing medium and RAW264-conditioned medium, which contained the secretome released from boron-stimulated RAW264, and its osteogenic differentiation is evaluated.

This study aimed to determine the influence of air abrasion on the shear bond strength (SBS) of universal adhesives when using different abrasive powders. The AquaCare Twin served as the injection device. The prepared bovine dentin specimens were air- abraded with alumina particles or bioactive glass before applying the universal adhesive (All Bond Universal, Clearfil Universal Bond Quick ER, or Scotchbond Universal Plus Adhesive).

Multi-tissue regeneration remains a critical clinical challenge due to the lack of solutions that can replicate the hierarchical heterogeneity of such complex interfaces. While biofabrication approaches, such as extrusion-based, allow replicating robust, biomimetic, and layered designs, constructs are usually hindered by inadequate phase/layer integration, poor filler dispersion, and mismatched rheological and mechanical performances. This study introduces an ink engineering strategy as a solution for integrating natural-based nanocomposites in multi-tissue regenerative approaches.

Phosphate and phosphate invert glasses contain various elements, with a wide range of compositions. Recently, our group reported orthosilicophosphate glasses (SPGs) and the glass network structure composed of orthophosphates and orthosilicates crosslinked by cations. ZnO is an intermediate oxide that improves the chemical durability of glass.

Background: Reconstruction of head and neck mucosal defects presents unique challenges due to the anatomical complexity and functional demands of the region. Artificial biomaterials such as collagen and polyglycolic acid (PGA) sheets have gained clinical traction owing to their ease of use and reduced surgical burden. However, limitations such as local inflammation, degradation-related complications, and mechanical instability-particularly in highly mobile areas like the tongue-continue to hinder their broader application.
