CATEGORIES OF BONE GRAFT
Bone graft selection is critical to the outcome of any bone healing procedure. There are currently over 200 different bone grafts available to surgeons today, each with substantial differences in technology, materials, mechanisms of action, indications, and clinical evidence.
Bone grafts can be categorised based on:
- Composition
- Mechanism of action (MOA)
- Approved indication
- Performance data
Allograft Bone Graft
There are many different allograft products or forms available for use. Some allograft tissue functions through osteoconduction and mild osteoinduction when demineralised, and include mineralised tissue, demineralised tissue, and allograft tissue plus cells.
Grafton™ demineralised bone matrix (DBM) is the most utilised and scientifically studied DBM brand.1 Our aseptic processing technology preserves the function of naturally occurring growth factors — yielding Grafton DBM’s osteoinductivity scores. Proprietary fiber technology offers enhanced osteoconductive scaffold.2
- Composition: Donor bone and tissue
- Demineralised MOA: osteoconductive and osteoinductive.
Synthetic Bone Graft
An osteoconductor, synthetic autograft extender bulks up the supply of available autograft bone.
- Composition: Synthetically produced minerals and ceramics
- MOA: Provides an osteoconductive passive scaffold for bone formation
