Bone Preservation Grafting

The more commonly accepted term for this technique is "Ridge Preservation Grafting."  When a patient is expecting to have a tooth replaced with a dental implant,  the tooth should be removed "through the socket" in a bone sparing technique (see "Dental Extractions" tab) rather than removing inordinate amounts of surrounding bone.   In addition, a bone graft is then placed in the socket to encourage the bone surrounding the socket not to "wilt" (resorb) during healing.  When a tooth is removed, the walls around the socket are very thin and tend to resorb as the socket heals, such that it often heals so narrowly that a small implant must be placed which may not have the longevity of a size closer to that of the tooth which was removed.  When bone graft is placed in the socket, the socket tends to shrink much less.  In the case of molar teeth (big back teeth with 2-3 roots), if ridge preservation is not done,  sometimes the replacement requires two smaller implants (at twice the cost) instead of one larger sized implant.  In addition, sometimes the roots of teeth are actually outside the bone or an infection has destroyed part of the bone.  Is such instances, a membrane also must be placed to protect the bone and prevent it from breaking down further.
