Palo Alto Dentist Dr. Hansen offer bone grafting in order to improve the results of dental implants. Bone grafting is a routine, painless and straight forward process. When a tooth is removed the socket will collapse inward decreasing the amount of available bone for the future implant. In the old days, bone grafting required the use of the patient’s own bone taken from another area of the mouth. Thankfully this is no longer necessary, as we can use a xenograft or an allograft at the time the tooth is removed to preserve the socket and amount of available bone. The human body is then “fooled” biochemically into resorbing and replacing the graft with the patient’s own bone.
