Periodontal Subperiosteal Tunnel Bone Graft Technique

Tunnel bone grafting according to the proposed method can be used when an individual has a facial bone defect due to periodontal disease, cleft palate or trauma. The proposed method can be utilized for implant placement, it reduces wrinkles and supports facial muscle in order to make the individual look younger. The method can also be used to create a thicker alveolar ridge in order to stabilize full dentures or partial dentures. Its advantages over conventional guided bone regeneration techniques is that the proposed method is minimally invasive and lessens trauma to patients, prevents soft tissue opening, and reduces surgery time. Specifically, it minimizes the incision size and thus reduces trauma to the patient. Further, this reduces the risk of complications, including excessive bleeding, due to the minimization of the incision size. There is also considerable reduction in post surgery swelling using the proposed method as opposed to conventional techniques.
