GelMA-based moldable and rapid-curable osteogenic paste inspired by ceramic craft for alveolar bone defect...

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Oral and Maxillofacial Surgery

Background:

• Alveolar bone defects are a major challenge in dentistry, affecting dental implants, orthodontics, and oral restoration.
• Current bone graft stabilization relies on blood coagulation, which is slow and ineffective in patients with coagulation disorders.
• Existing injectable gels have low viscosity and depend on natural defect formation for curing.

Purpose of the Study:

• To develop an injectable, moldable, and rapidly curable hydrogel for alveolar bone defect regeneration.
• To create a coagulation-independent bone graft stabilization method.
• To address limitations of current treatments for alveolar bone defects.

Main Methods:

• Developed a ceramic-craft-inspired osteogenic (CIO) hydrogel using gelatin methacrylate (GelMA), nanoclay, and bone grafts.
• The injectable paste allows for manual shaping without molds.
• Rapid crosslinking within 15 seconds under UV irradiation.

Main Results:

• The CIO hydrogel demonstrated moldable and curable properties for bone defect regeneration.
• Achieved rapid, coagulation-independent bone graft stabilization.
• The material provided malleability and strength after UV crosslinking.

Conclusions:

• The CIO hydrogel presents a promising, moldable, and rapidly crosslinking solution for alveolar bone defect regeneration.
• This approach offers a breakthrough in overcoming the limitations of current bone grafting techniques.
• Potential to significantly improve outcomes for dental implants, orthodontics, and oral restoration procedures.
