Bone regeneration with biomaterials and active molecules delivery

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Drug Delivery Systems

Background:

• Synthetic bone substitutes often lack inherent bioactivity for optimal bone regeneration.
• Integrating drug delivery systems offers a strategy to impart necessary bioactivity to biomaterials.

Purpose of the Study:

• To review recent advancements in combining biomaterials with drug delivery for enhanced bone regeneration.
• To summarize strategies for supplementing biomaterials with active molecules to improve bone healing.

Main Methods:

• Literature review of recent research in biomaterials and drug delivery for bone regeneration.
• Analysis of studies supplementing bone biomaterials with small or biological molecules.

Main Results:

• Biomaterial functionalization with active species significantly improves osteoprogenitor cell recruitment and osteoinductivity.
• Drug delivery systems enhance anabolic, angiogenic responses, and regulate bone metabolism for better regeneration.

Conclusions:

• The combination of biomaterials and drug delivery is a key strategy for developing advanced synthetic bone substitutes.
• This synergistic approach holds significant promise for improving bone regeneration outcomes.
