Synthetic bone graft materials play an important role in reconstructive orthopaedic surgery. Sintered at high temperature, the synthetic bone graft materials are available in blocks and granules for orthopaedic applications. Synthetic bone graft materials are also available and used in periodontonlogy and maxillo-facial surgery.
The major functions of bone graft materials include promoting osseous ingrowth and bone healing, providing a structural substrate for these processes, and serving as a vehicle for direct antibiotic delivery. There are three primary types of bone graft materials:
The major functions of bone graft materials include promoting osseous ingrowth and bone healing, providing a structural substrate for these processes, and serving as a vehicle for direct antibiotic delivery. There are three primary types of bone graft materials:
1. Allografts,
2. Autografts, and
3. synthetic bone graft substitutes.
Unlike most other tissues, bone tissue has the ability to regenerate completely if provided the space into which to grow. And because of this ability, bone grafting is possible. The biologic mechanisms that provide a rationale for bone grafting are osteoconduction, osteoinduction and osteogenesis.
