Bone augmentation is a term that describes a procedure used to "build" bone so that dental implants can be placed. These procedures typically involve grafting (adding) bone or bonelike materials to the jaw. The graft can be your own bone or be processed bone. After grafting, you have to wait several months for the grafted material to fuse with the existing bone. Synthetic grafted materials either cause surrounding bone to grow into the graft or cause cells around the graft to change into bone.After bone augmentation, dentists usually wait four to nine months before placing implants.
Most bone augmentation procedures involve the use of bone grafts. An excellent choice for a bone graft is your own bone. This most likely will come from your chin or ramus (the back part of your lower jaw). If your dentist cannot get enough bone from these areas, he or she may need to get bone from your hip or shin bone (tibia) instead. The hip is considered to be a better source because the hip bone can provide a large amount of bone.
Synthetic materials also can be used for bone grafting. Newer products, such as bone morphogenetic protein-2 (BMP-2), also are available. BMP-2 stimulates certain body cells to turn into bone, without grafting.
