45S5 Bioactive Glass is a clinically proven bioactive material known for excellent bone regeneration, osteoconductivity, and biocompatibility. It stimulates hydroxyapatite formation and is widely used in bone repair, dental, and medical applications.
Bioactive glass is a novel type of biomaterial used for tissue regeneration, possessing biological activity, compatibility with both soft and hard tissues, and controllable degradation rates.
The most representative bioactive glass used clinically for bone, tooth, and skin wound repair is 45S5, which belongs to the Na2O-CaO-SiO2-P2O5 quaternary system.
This novel medical material exhibits excellent biocompatibility and, in a physiological environment, can generate a bone-promoting hydroxycarbonate apatite mineralization layer through mineralization deposition on its surface, thereby achieving chemical bonding between the material and the host tissue.

I.Promoting Bone Bonding
The implant surface can form strong chemical bonds directly with bone tissue.
This is not merely physical adhesion, but the formation of a hydroxyapatite (HCA) layer similar to natural bone
II.Promoting Osteogenesis and Bone Regeneration
●Release of ions such as Ca²⁺, SiO₄⁴⁻, PO₄³⁻, and Na⁺
●Stimulation of osteoblasts:
o Increased cell proliferation
o Promotion of osteogenesis-related gene expression
o Accelerated new bone formation
III. Induction of Hydroxycarbonate Apatite (HCA) Layer Formation
The following classic reaction process occurs in body fluids:
1.Na⁺ exchanges with H⁺, creating an alkaline environment.
2.The Si-O-Si network breaks down, forming Si-OH.
3.Ca²⁺ and PO₄³⁻ accumulate on the surface.
4.An HCA layer is formed (similar to natural bone mineral).
IV.Antibacterial and Infection Inhibition
●Ion release increases local pH and osmotic pressure.
●Inhibits the growth of various bacteria.
●Can reduce the risk of postoperative infection.
V.Controlled Degradation and Tissue Replacement
●The material gradually degrades in the body.
●Simultaneously, it is replaced by newly formed bone tissue.
●The degradation rate can be controlled through the composition ratio and particle size.
1.Orthopedics / Bone Defect Repair: Direct implantation of granules or powder into the defect; or used to create bone scaffolds.
2.Dentistry: Powder added to toothpaste, dental patches, and periodontal filling materials.
3.Wound Repair / Soft Tissue Engineering: Combined with hydrogels, dressings, or membranes, in micro/nanoparticle form.
4.Cosmetics / Anti-aging Repair (R&D stage): Micro-powder added to face masks or cosmetic materials.
5.Antibacterial Materials: Combined with hydrogels, dressings, or coatings.
