Bone grafting procedures are usually necessary if there is not enough bone available to place dental implants or if any vital anatomy is in the way. Today, bone grafting procedures have become almost an integral part of implant reconstruction. In many instances, a potential implant site in the upper or lower jaw does not offer enough bone volume or quantity to accommodate a Rootform Implant of proper size or in the proper place. This is usually a result of bone resorption that has taken place since one or more teeth (if not all) were lost. Bone Grafting procedures usually try to re-establish bone dimension, which was lost due to resorption. Many years ago the lack of bone posed a considerable problem and sometimes implant placement was impossible because of that. Today, however, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width (and for Rootform Implants we always try to go for as long and wide as possible), it also gives us a chance to restore the esthetic appearance and functionality better.
Type of Bone Grafting Materials
With respect to the Bone Graft material used, we have to differentiate between several choices. All materials can be categorized into five different categories:
• Autograft or autogenous bone graft
• Allograft or allogenic bone graft
• Xenograft or xenogenic bone graft
• Alloplast or alloplastic bone graft
• Growth Factors
Each of the bone graft materials is usually developed with a specific purpose or advantage in mind. Your surgeon will make a decision with respect to the bonegraft material, based on your individual needs and the latest research in that field.
