Abstract
|
|
|
|
A variety of grafting materials are available for use in implant dentistry. Sufficient bone is needed for the long-term stability of the implant, and the possibility of bone regeneration is currently more predictable than in the past. The bone materials are classified as follows: autogenous bone, allografts, xenografts, alloplasts. Autogenous bone is considered the gold standard material because of its main properties: osteogenetic, osteoinductive, osteoconductive. However, disadvantages such as unpredictable resorption and donor site morbidity have led to the need for bone substitutes. Allografts harvested from cadaver and demineralized freeze-dried bone are not only osteoconductive but also osteoinductive. Xenografts are obtained from another species and possess osteoconductive potential. Alloplasts are a bone material that is synthetic or in a natural form and possess only osteoconductive capabilities. In this article, we analyze the properties of the bone grafting materials that are currently available and discuss their efficacy in implant dentistry.
