Description

Bioactive glass stands out as an exceptionally versatile material, demonstrating profound promise across numerous applications in tissue engineering. Its utility is particularly evident in bone, cartilage, and dental repair. This material exhibits a remarkable ability to bond directly with living tissues, actively stimulating their regeneration. Such inherent capabilities point toward exciting future directions in tailoring these materials for increasingly specific and complex clinical needs [1]. Within the specialized field of dentistry, bioactive glasses are consistently making significant advancements, providing innovative solutions for tooth repair, remineralization processes, and even intricate root canal treatments. Ongoing research actively explores the latest developments, encompassing their practical use in addressing sensitive teeth and their substantial potential in regenerating damaged dental tissues, effectively charting a progressive path for future innovation in oral healthcare [3]. At a fundamental level, understanding precisely how bioactive glass induces biomineralization is absolutely crucial for fully optimizing its extensive therapeutic effects. Detailed analysis meticulously dissects the complex biochemical interactions occurring at the material-tissue interface, thereby shedding clear light on the formation mechanism of hydroxyapatite and its indispensable role in the seamless integration of the glass within the body's natural bone structure [8].

The strategic combination of mesenchymal stem cells with bioactive glass represents a particularly powerful and synergistic approach for significantly enhancing bone regeneration. Comprehensive systematic reviews consistently analyze the current body of literature, definitively confirming that this combined strategy substantially improves bone repair outcomes. This is achieved by simultaneously providing both robust structural support for new tissue growth and crucial cellular cues that guide and stimulate the repair process [2]. Furthermore, the groundbreaking advent of 3D printing technologies has fundamentally revolutionized how bioactive glass can be applied, especially in the context of creating intricate and precisely designed scaffolds for bone tissue engineering. This additive manufacturing capability allows for exceptionally precise control over the scaffold's architecture, which is critical for enhancing both the mechanical strength required for load-bearing applications and the biological performance essential for optimal bone regeneration [5].

Beyond their widely recognized tissue regeneration capabilities, bioactive glasses also impressively exhibit fascinating and vital antibacterial properties. Various reviews deeply delve into how these advanced materials actively combat microbial growth, a critically important aspect for effectively preventing implant infections, which remain a major clinical challenge. These studies meticulously outline the specific mechanisms and compositional strategies that can be employed to further enhance this beneficial antimicrobial feature [4]. This inherent antimicrobial capability also extends its utility to advanced wound care, where bioactive glass is rapidly emerging as a highly promising advanced wound dressing material. Research clearly explores its remarkable capacity to accelerate the healing process through direct interaction with various tissues, actively promoting vital cell proliferation and simultaneously providing an essential antimicrobial environment, collectively offering a substantial and much-needed upgrade to conventional wound care practices [9].

While undeniably renowned for its efficacy in bone repair, bioactive glasses additionally hold considerable promise for regenerating soft tissues, broadening their therapeutic scope. This review specifically explores their intricate mechanisms involved in promoting angiogenesis (the formation of new blood vessels) and vital cell proliferation, thereby offering valuable insights into their diverse potential applications in areas such as general wound healing, advanced skin repair, and even challenging nerve regeneration [7]. Intriguingly, bioactive glasses are also now emerging as compelling potential candidates in the challenging field of cancer therapy. Scoping reviews meticulously examine their truly diverse roles, spanning from efficiently delivering anti-cancer drugs directly to tumor sites to exhibiting inherent cytotoxic effects directly on cancer cells, effectively opening up entirely new and innovative avenues for cancer treatment [6].

Turning to highly advanced applications, bioactive glass nanoparticles are proving to be incredibly versatile and powerful platforms for both targeted drug delivery and advanced theranostics. This comprehensive review specifically highlights their exceptional ability to effectively load and precisely release various therapeutic agents with controlled kinetics. Concurrently, these sophisticated nanoparticles also offer robust imaging capabilities, collectively paving the way for truly targeted treatments and significantly enhanced diagnostic tools within the expansive field of biomedicine, representing a substantial leap forward in personalized medicine [10].
