Autografts |
Patient’s own bone |
Osteogenic, osteoinductive, osteoconductive, biocompatible |
Preferred for its biological properties |
Best integration and growth potential |
Limited availability, donor site complications |
[76] |
Allografts |
Donor human bone |
Various forms, may be processed |
Useful when autograft quantity is insufficient |
Reduced donor site morbidity |
Risk of disease transmission, immune response |
[76] |
Xenografts |
Bone from another species |
Processed for biocompatibility |
Alternative when human bone is not preferred |
No risk of disease transmission from human |
Cross-species compatibility issues |
[77] |
Bone Graft Substitutes |
Synthetic or naturally derived |
Includes ceramics, cements, glass |
Fill bone defects and provide a scaffold |
Variety of options and ease of use |
Lack of osteogenic, osteoinductive, osteoconductive, and biocompatible properties |
[76] |
Vascularized Bone Grafts |
Bone with its own blood supply |
Improved healing in avascular areas |
Used in challenging defects |
Superior in areas with poor blood supply |
Technically demanding, donor site morbidity |
[78] |
Custom 3D-Printed Implants |
Based on patient-specific imaging |
Tailor-made, biocompatible |
Perfect fit for defect area |
Custom-fit, reduces adaptation issues |
High-cost, complex pre-surgical planning |
[79] |
Titanium Mesh |
Metallic scaffolds |
Support and allows bone growth |
Spinal fusion surgeries |
Immediate structural support |
Biological incompatibility, subsidence, stress shielding, and radiopacity |
[80,81] |
Polymers |
Biodegradable or non-biodegradable |
Scaffolds for bone regeneration |
Gradual bone regeneration |
Versatility and controlled degradation |
May induce inflammatory response |
[82] |
Metal Alloys |
Stainless steel, cobalt-chromium, etc. |
Used for structural support |
Load-bearing area repair |
High strength and fatigue resistance |
Stress shielding, toxic ion release, secondary surgery, and imaging artifacts |
