Periodontal Subperiosteal Tunnel Bone Graft Technique

Abstract

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.

Claims

1. A method of performing periodontal surgeries in order to correct damage to the alveolar ridge that has decreased bone mass to such a degree that it is not medically advisable to place dental implants, which comprises the following steps: making a vertical incision of 6 mm to 10 mm, but at the most 15 mm, beyond the mucogingival junction at the mesial side of the area that needs horizontal bone augmentation, placing periosteal elevators to separate the periosteum from alveolar ridge on the buccal side, scraping the alveolar bone area using a back action chisel or small head bone file, inserting a collagen membrane inside of the newly created tunnel, placing a freeze dried bone allograft cortical or cortical cancellus powder mixed with saline solution or the patient's blood between the collagen membrane and the alveolar bone surface in an amount sufficient to fill the void created, suturing the incision, waiting approximately six months prior to placing the dental implant

2. A method of performing periodontal surgeries in order to correct damage to the alveolar ridge that has decreased bone mass to such a degree that it is not medically advisable to place dental implants according to claim 1, further comprising at the time of placing sutures, also placing an external mattress suture over the recipient site to stabilize the graft area.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention relates generally to methods of performing periodontal surgeries. It is a method of performing periodontal surgery in order to correct damage to the alveolar ridge that has decreased bone mass to such a degree that it is not medically advisable to place dental implants. The sources of damage could include trauma, facial bone defects due to periodontal disease, or cleft palate.

[0014] A 6 mm to 10 mm, but at the most 15 mm, vertical incision is made beyond the mucogingival junction at the mesial side of the area that needs horizontal bone augmentation. Then, periosteal elevators are used to separate the periosteum from alveolar ridge on the buccal side. The alveolar bone area is scraped using a back action chisel or small head bone file. A collagen membrane is inserted inside of the tunnel. Then, a freeze dried bone allograft cortical or cortical cancellus powder mixed with saline solution or the patient's blood is placed between the collagen membrane and the alveolar bone surface in order to fill the void created and to supplement the area with decreased bone mass. The incision is sutured. The patient is given approximately six months of time to heal and for the bone graft to convert into living bone. Afterwards, the implant can be placed using accepted conventional methods.

[0015] One variation on the within method includes, at the time of placing the sutures, also placing an external mattress suture over the recipient site to stabilize the graft area.
