Bone grafting is the process of using your own bone to replace missing bone. Consider this, it is natural for a person to lose bone around a missing tooth. However, before implants can be placed the bone must be strengthened. Your bone tissue is used to fill the void left by the missing tooth/teeth. After about 2-4 months the bone will grown back. As a result of bone grafting, there is a much higher rate of implant(s) success.
