A dental bone graft surgery requires taking a piece of bone from another part of the body and implanting it into the jawbone, according to Mayo Clinic. Dental bone graft surgery is typically performed if the jaw is too soft or not thick enough before a dental implant surgery can be performed. Depending on the patient's responsiveness to the bone graft surgery, it can take 9 months to grow enough new bone to be ready for surgery, but in some cases, the bone grafting required is minor, and it can be done just before the implant surgery.
According to the Mayo Clinic, bone grafting is sometimes needed before a dental implant surgery can be performed because a patient's jawbone is either too soft or too thin, making it weak. If the jawbone is too weak and a dental implant surgery is performed, the jawbone will not be strong enough to withstand the pressure exerted by chewing and will not support the implant. The grafted bone must be in place long enough for new bone growth to occur and strengthen or thicken the jawbone sufficiently. Some patients only need minor grafting and can therefore receive a bone graft just before the implant surgery. However, other patients who require more substantial bone grafting can take up to 9 months to grow enough new bone.
