Bone Grafting for Dental Implants – After a tooth is extracted, the bone in the area will collapse slightly over time as it is no longer needed to support the tooth.  In some cases, the collapse is more significant, and lead to insufficient bone for implant placement.

Types of Bone Grafts – There are multiple types of bone graft materials that are used.  Most commonly, allograft bone (surgically donated bone from a tissue bank) or autogenous bone (your own bone taken from the jaw) are used.  In addition, other options are available.  Your periodontist would be happy to discuss with you the various options for your particular situation.

Timing of Bone Grafting

Socket Preservation at the time of extraction: One way to prevent this collapse of the bone is to place a bone graft at the time of tooth extraction.  After the tooth is removed, a bone graft material is placed in the “socket” of where the tooth root used to be.  The graft will prevent collapse of the bone, and “hold space” for the future implant.

At the time of implant placement -  Many times minor bone grafting can be performed at the same appointment as the implant placement.  In this procedure, a bone graft material is placed around the implant to increase the available bone and support of the implant.

Prior to implant placement – In some situations there may be a large deficiency in the bone due to an injury, periodontal disease, or other reasons.  In these cases, bone grafting may need to be performed first with several months of healing prior to implant placement.
