Autogenous Periosteal Pedicle Graft Versus Pericardium Membrane in Management of Periodontal Intrabony Defects in Stage III Periodontitis

Under Local Anesthesia , intrasulcular incisions using surgical blade #15c Then, a full thickness mucoperiosteal flap will be raised . Then, the granulation tissue in the intrabony defect will be debrided and the root will be planned using manual and ultrasonic instruments followed by saline and chlorohexidine irrigation till obtaining a healthy sound bone surface.

Bovine Xenograft material packed into the debrided defect.

"* Vertical releasing incisions will be used if necessary for better access.~* The periosteal membrane will be separated from this flap and released with one vertical incision mesially and one horizontal incision apically . Posteriorly, the periosteum remained attached to the mucoperiosteal flap for adequate blood supply.~* periosteal membrane will be turned over to cover this defect completely and sutured with the lingual flap with a synthetic 6-0 bioabsorbable Vicryl suture. \*The soft tissue flap will be sutured with 5-0 nonabsorbable prolene suture material and a periodontal dressing was given."

A pericardium membrane was adapted for defect coverage and sutured with the lingual flap with a synthetic 6-0 bioabsorbable Vicryl suture.
