Bone Allograft Particulates
Mineralized Cancellous:
- Ideal inner surface area and porosity allows for immediate, stable clot formation
- Mineralized bone provides osteoconductive scaffold for efficient turnover to vital host bone
- Optimal particle structure and shape for natural and complete bone fill
Mineralized Cortical-Cancellous:
- Mineralized bone provides osteoconductive scaffold for efficient turnover to vital host bone
- Cancellous (~60%) provides ideal porosity for rapid clot formation
- Cortical (~40%) provides excellent space maintenance with slower resorption
Mineralized Cortical:
- Mineralized bone provides osteoconductive scaffold for efficient turnover to vital host bone
- Cortical bone provides excellent space maintenance with slower resorption
- Optimal particle density for long-term volume maintenance
Demineralized Cortical:
- Demineralized bone can promote osteoinductive BMP activity
- Excellent for small periodontal defects
- Optimal particle density for clot stability
Demineralized Cancellous Sponge:
- Demineralized bone promotes osteoinductive BMP activity for ectopic bone generation
- Compresses during placement, yet expands to maintain space
- Rapidly absorbs blood for quick, stable clot formation
- Unlike block grafts, sponge strip won’t cause exposures or soft tissue perforation
