How are dental bone grafts done for bridges?

Open ended question: It depends. Are the bone grafts being done to the supporting teeth or are the grafts being done to the gum tissue for cosmetic reasons. This needs to be discussed with the attending dentist or oral surgeon.

A few ways: Bone can be added to tooth sockets after extractions to help support implant placement. In addition, bone can be placed against existing bone either in layers or in sections to widen a narrow ridge. Without knowing more about your individual situation, it is hard to discuss this further.

Bridge abutment: If is very tricky to get a good result for grafting bridge abutment. Some times the bridge should be removed with the contact removed from the abutment. Temporary should be placed. Prior to grafting, the lesion must be scaled and debrided, with proper healing in the soft tissue. Graft should be fully covered with soft tissue. Necessary measure must be carried out to prevent infection.

Ask surgeon: There are many techniques available. Your question should be posed to the surgeon actually doing the procedure. He\she can answer all your questions.
