Osseous surgery is a procedure that reshapes the bone which holds your teeth in place. Osseous surgery commonly treats periodontitis. Patients with periodontitis experience defects in the bone around their teeth. The osseous surgery removes those defects. Prior to the surgery, the patient undergoes a periodontal treatment that consists or scaling and root planing. A local anesthetic is administered to minimize the pain. Depending on the extent of the defects, the deformed bone is removed, and the rest is shaped. Bone grafting material is used where the defects are too large to be treated with only reshaping. Osseous Grafting is a routine procedure, with a high success rate.
