OX bone granules

Cortical-cancellous or cancellous-only natural granular bone grafts, enzyme- deantigenated, showing bone collagen preserved and different granule sizes.

1. Collect some autologous bone, if possible (blur, scraper) and put it in a sterile container
2. Open the bottle
3. Drop the bottle content into the sterile container
4. Hydrate with sterile physiological solution for 1-2 minutes 5. Graft the mixture
6. Protect the grafted site with a proper membrane

General hints and precautions:
Grafting the granules:
Place the granules in the grafting site in order to make them stable and still. Avoid excessive compression. Too much compression can make the space between adjacent granules decrease to such a point that angiogenesis is hindered.
