Bone Grafts | Advantages | Limitations | Clinical Application |
---|---|---|---|
Autografts | Osteoinductivity Osteoconductivity Biocompatibility Bone mechanical properties |
Postoperative morbidity Limited volume Increase in surgical time Additional anesthetic procedure required |
Gold standard in trauma and dentistry when possible |
Allografts | Osteoinductivity Osteoconductivity Biocompatibility High availability Reduced surgical time |
Lower osteoinductive capacity than autografts Inferior mechanical properties Costly and laborious processing Potential risk of diseases transmission |
Osteoarticular reconstructive surgery Foot and ankle surgery |
Mammalian xenografts | Bone tissue physiological similarities Osteogenic and bone inductive properties Excellent support for bone colonization |
Low tissue remodeling Stay mainly unaltered on the host bone Batch variability |
Filling of bone voids following trauma, reconstruction in orthopedics, spinal surgery, periodontal, oral, and maxillofacial surgery |
Marine xenografts | Interconnected porosity Hierarchical structure Osteoconductivity Availability in large quantities |
Weak mechanical properties Fast degradation Batch variability |
Bone fillers in non-load bearing regions |
