Bone grafting is a surgical procedure often performed in preparation for dental implant placement or as part of periodontal disease treatment. In this article, we answer a common question: What is the best bone grafting material?
What Is the Best Bone Grafting Material?
The main aim of bone grafting is to prompt the jawbone to regenerate and restore its structure when it is damaged by gum disease or undergoes bone resorption. The most commonly used types of bone grafts include autografts, allografts, xenografts, and synthetic grafts. Each type has its own advantages and disadvantages in particular cases, and there is no definitive answer as to which material is best.
Your doctor chooses the most suitable bone grafting material after considering the following points:
- How much bone needs to be regenerated
- Whether rapid healing is needed
- Cost and availability
- Patient health and preferences
Let us examine the main pros and cons of each type of bone graft in more detail.
Autografts
Autografts are derived from your own bone, often from the hip bone. Typically, autografts have the highest success because they are biologically active and fully compatible, and are often used for major reconstructions where maximum bone growth is needed. The effectiveness of autografts is determined by their containing living cells, growth factors, and natural bone matrix.
The disadvantage of autografts is that they require a second surgical procedure to harvest the graft. Thus, it may cause greater discomfort to the patient and prolong healing, especially when the natural regenerative capacity of the body is already compromised.
Procedures involving autografts are typically more expensive than those with other materials, as they require two surgeries, extra operating room time, and may involve additional hospital costs.
Allografts
Allografts are made of bone from a human donor (typically a cadaver). The donors are screened, and the material is processed before it is used to make a graft. This processing involves removing all blood, fat, and soft tissue, and cleaning with sterile solutions to reduce bacteria and other organic material that could cause rejection.
Even though some people might experience negative emotions when offered a graft derived from a donor, it is absolutely safe. It remains one of the most effective solutions comparable to grafts derived from the patient’s own bone.
Allografts eliminate the need for an additional surgical procedure and are widely available. However, they lack live cells, so biological activity is lower than that of autografts.
Xenografts
Xenografts are derived from animal bone tissue (typically from a cow or a pig) and are also preliminarily processed to remove organic components. This type of graft is common and widely available. However, it is best for maintaining bone volume and might not be the most optimal solution for actively stimulating new bone formation.
Synthetic Grafts
Synthetic grafts are manufactured in labs from materials such as hydroxyapatite (HA), which is similar to natural bone mineral, β-tricalcium phosphate (β-TCP), biphasic calcium phosphate (BCP), and bioactive glasses.
The advantages of synthetic grafts include:
- They do not pose a disease transmission risk
- Customization
- Consistent quality
- The lowest price compared to other types of grafts
However, synthetic grafts primarily serve as a physical scaffold, and regeneration may be slower than with other types, as they lack living cells and natural growth factors.
