The morbidity and mortality of patients with chronic wounds increase with the aggravation of social aging. The sharp rise in the burden of the medical system leads to an increased demand for high clinical efficacy, developed therapies, and innovative products. Bioactive glass (BGs) is well considered as a promising clinical material in biomedical fields, especially in wound healing. BGs stimulate the production of growth factors due to its unique controlled dynamic ion release properties, enhancing cell proliferation and regulating the gene expression of related cells. Particularly, the bioglass composed of borate and borosilicate exhibits a controllable degradation rate, which can continuously release functional ions and regulate the wound microenvironment for various pathological stages of wound healing to induce angiogenesis and accelerate the steady recovery of pathological wound tissue. In over 50 years of clinical and fundamental research, the efficacy of bone grafts in repairing bone tissue has been conclusively demonstrated, and biomaterial scientists have analyzed in depth the molecular biological mechanisms underlying the interaction between BGs and bone. Emerging applications of BGs for soft tissue repair still require a further research. This review represented a relationship between the structure and properties of boric acid/borosilicate bioactive glass, focusing on the clinical application research progress and future prospects for the development of bioglass wound dressings.

Complicated factors make chronic wounds difficult to manage. The excessive inflammation is a key factor in wound pathogenesis. To treat chronic wounds, it is essential to comprehend how to prevent the development of microorganisms at the wound site, reduce ROS production and tissue inflammation, induce cells to release more growth factors, alter the cell vitality, chemotaxis and mobility, and initiate new blood vessel growth. The development of BGs reveals its positive role in the treatment, restoration, and regeneration of hard and soft tissues in the human body. Compared to conventional inactive biomaterials, its clinical application significance and potential are substantial. Borosilicate bioactive glass (BBGs) with a unique glass network structure has a faster degradation rate, compared to silicate bioactive glass, making it suitable for soft tissue repair. BBGs with specific functional properties can be produced via adjusting the proportion of biologically active elements (i.e., Na, K, Ag, Au, B, Ca, Cu, Co, Ga, Mg, Sr and Zn) doped into the glass network structure according to the therapeutic needs of target tissues or organs. BBGs with different ion compositions can continuously release functional ions and regulate the wound microenvironment for different pathological stages of wound healing, thereby inducing angiogenesis and accelerating the steady-state recovery of pathological wound tissue. In addition to the superior clinical therapeutic effect by using fiber as clinical application dressing, BBGs can also combine with polymer to form functional hydrogel dressing, and can prepare multi-functional composite materials by electrospinning technology or 3D tissue engineering printing technology to meet the personalized needs of different stages of wound repair. The majority of chronic wound patients are affected with the intensification of global aging. Boric acid/borosilicate bioactive glass wound repair materials are low-cost, easy to store, and have significant social and economic benefits.
