To place dental implants, you must have enough height and width of bone and it must be in the right locations so that when the final tooth restoration/crown is placed, that new tooth will be in a functional and aesthetic position.
Bone grafting is the process of adding bone to where you need the bone in order to facilitate dental implant placement in the exact location to achieve your treatment goals. Bone grafting can be performed with various bone substitute products, or through the use of your own bone and moving it to where it is required. With modern bone grafting techniques and materials, it is nearly possible to graft any area of the upper and lower jaws to facilitate dental implant placement.
