<p>Bioactive glasses (BGs) have become a critical class of materials in regenerative medicine, particularly for bone repair and tissue regeneration. This review provides an in-depth comparison of three primary types of bioactive glasses: silicate-based, borate-based, and phosphate-based. Each type exhibits distinct characteristics that influence its performance in biological environments. Silicate-based BGs are the most extensively studied due to their remarkable osteoconductivity, bioactivity, and ability to form strong bonds with bone tissue. Efforts to enhance their mechanical properties and optimize degradation rates have led to innovations in their composition and processing, improving their clinical applicability in bone grafts and implants. Although borate-based BGs have been less extensively explored, they show promising attributes, including superior antibacterial properties and enhanced cell proliferation, making them ideal for infection-prone areas and soft tissue regeneration. Phosphate-based BGs, on the other hand, are particularly notable for their resemblance to natural bone mineral and their enhanced osteogenic potential, offering unique advantages for bone tissue engineering. This review underscores the strengths and limitations of each type of bioactive glass, providing valuable insights into their potential future clinical applications in tissue engineering and regenerative medicine.</p>
