Over a period of time, the jawbone in the area of the missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and amount of bone to place an implant. In this type of situation, we now have the ability to grow bone when needed. This not only provides the opportunity to place an implant of proper length and width, it also enables us to restore functionality and an esthetic appearance.
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injury. The bone is either obtained from a tissue bank or from the patient themselves. Bone grafting can also be placed in the sinus area to replace bone in the upper posterior areas and in large areas to repair defects. These defects can be the result of traumatic injury, tumor surgery or congenital defects. In severe cases, the ridge has resorbed and a bone graft is placed to increase the height and/or width. This technique is used to restore the lost bone dimension when the jaw is too thin to place an implant. The ridge of the jaw is expanded, the bone graft material is placed and allowed to mature for 6 to 9 months before placing the implant.
