“…This effect of MgO is critical and beneficial for the processing of bioactive glasses, since a large interval between T c and T g will enable sintering to occur without formation of crystalline phases . In addition, it is possible to modulate the thermal expansion coefficient (TEC) of silicate glasses by changing the MgO content, which can be predicted, in principle, by using Appen's model . According to this model, the increase of MgO content in a bioactive glass composition should decrease the glass TEC.…”

The importance of Mg in the human body, its key role in bone tissue development, in addition to its application to improve and modify physical, thermal, and mechanical properties of bioactive silicate glasses, make Mg a very interesting element as a component of bioactive glasses for medical applications. Although Mg is a typical element in the composition of numerous developed bioactive glasses, the analysis of the literature reveals that further research is required to gain comprehensive understanding about the effects of MgO on bioactive glass structure and properties. This article presents a comprehensive overview of the field of Mg‐containing bioactive glasses discussing available compositions and summarizing existing knowledge on effects of MgO on glass properties. The biomedical applications of several developed glasses are discussed highlighting the distinct effects of Mg in relevant areas, such as bioactivity and cell response, and focusing on the most common applications for these glasses, such as bone cements, bioactive coatings, and scaffolds for bone tissue engineering. The effect of Mg on bone development is discussed and avenues for future research in the field are proposed, emphasizing the need to investigate unstudied properties of (already developed) Mg‐containing glass compositions, such as angiogenesis‐stimulating action and the effect on osteoclast functions, to develop new Mg‐containing bioactive glasses as well as to make products of different shape designs such as nanoparticles, fibers, and complex porous structures.

“…Bioactive glass (BG) coatings exhibit significant osteoinductive (stimulation of bone cells) and osteoconductive (surface suitable for bone growth) properties, interacting with the surrounding tissue at a cellular level through the release of biologically active ions [4][5][6][7]. In order to mimic the composite structure of natural bone, biodegradable polymer/BG composite coatings are increasingly being investigated for orthopedic purposes [8].…”

This study investigated the electrophoretic deposition (EPD) of the natural polymer zein combined with bioactive glass (BG) particles. Through the deposition of various BG compositions, namely 45S5 BG and Cu-doped BG, this work sought to demonstrate the ability of the films to potentiate the formation of hydroxyapatite (HA) in contact with simulated body fluid (SBF). Following incubation in SBF, the physical and chemical surface properties of the EPD films were evaluated using different characterization techniques. The formation of HA at the surface of the coatings following immersion in SBF was confirmed using Fourier transform infrared spectroscopy (FTIR). The results demonstrated HA formation in all coatings after seven days of immersion in SBF. Coating morphology and degradation of the zein films were characterized using environmental scanning electron microscopy (ESEM). The results confirmed EPD as a very convenient room temperature technique for production of ion releasing, bioactive, and antibacterial coatings for potential application in orthopedics.
