Bone graft surgery can be an excellent treatment to replace missing teeth, facilitate the formation of bone, and promote the healing process for wounds. The most common reasons people receive bone grafts are for multiple fractures not healing properly, fusing bones across a damaged joint, healing bones after joint replacement, and bone replacement after injury or disease. Choosing the right material for this routine and painless bone repair procedure can be daunting with the overwhelming array of options. How can you know which one to choose? Here’s how to choose the best material for your bone graft delivery system.
Ideal Bone Grafting Requirements
In order for a bone graft delivery system to be successful, four factors are required. There must be enough osteoblasts present in order to create new bone or it will fail. Sufficient blood supply is crucial for clot formation to serve as an anchor for the osteoblasts and cell viability. The bone graft delivery must be stable to avoid any disruption in the blood clot and to prevent any fibrous tissue from filling the area. There also can be no tension on soft tissue.
Three biological mechanisms help to heal and form new bone after bone graft delivery has taken place. Osteoconductive material behaves like a scaffold for new bone to grow from the native bone.
bone graft delivery system. Osteoinductive materials stimulate blood supply cells from adjacent bone to start new bone formation. Osteogenic materials supply viable osteoblasts.
Bone Graft Classifications
An autograft is a bone substitute taken from the patient’s own bone that is osteoinductive, osteogenic, and osteoconductive. Allograft materials are taken from human cadavers. While these materials are osteoconductive and osteoinductive, they don’t contain any osteogenic properties and may possibly transmit infectious diseases. Xenograft material originates typically from cows and pigs. This osteoconductive only material is deproteinized and demineralized to prevent an allergic reaction and disease transmission.
Alloplast material is synthetic and generally made using calcium phosphate-based ceramics. This osteoconductive material is most successfully used for periodontal reconstructive surgeries. It’s manufactured in a wide array of forms and properties. The most common materials used are hydroxyapatite, bioactive glass, tricalcium phosphates, and dicalcium phosphates.
Choosing the right material for your bone graft delivery system is vital to the health of your patient. When choosing your supplies, look for reputable bone graft companies that can guarantee the highest health and safety standards. By carefully weighing your options, you’ll be able to provide the top-notch medical care your patients deserve.
