Which material is used in combination with Type I Collagen for bone regeneration?

• A. Beta-Tricalcium Phosphate
• B. Titanium
• C. Hydroxyapatite Beads
• D. Demineralized Bone Matrix

Answer: (A)

When regenerating bone, you want a scaffold that provides a conducive structure for new bone to grow and that gradually resorbs as the new bone replaces it. Beta-tricalcium phosphate is a resorbable calcium phosphate ceramic that is osteoconductive, offering a robust three-dimensional framework for bone-forming cells and vascular ingrowth. Pairing it with Type I collagen combines a biologically active organic matrix with a mineral scaffold: the collagen improves handling and provides binding sites for cells, while the β-TCP supplies the mineral phase and resorbs in a controlled way as healing progresses. This synergy supports proper space maintenance and predictable bone formation, which is ideal for mandible or TMJ bone regeneration. Titanium is a non-resorbable metal and doesn’t remodel into bone. Hydroxyapatite beads are osteoconductive but resorb more slowly, offering less dynamic remodeling. Demineralized bone matrix is biologically active and contains collagen and growth factors, but the commonly used combination with a collagen carrier focused on here is the collagen-β-TCP composite, which provides a balanced, resorbable scaffold that aligns well with the natural remodeling process.
