Treatment of intrabony defect with a complicated, noncontained morphology using a combination of collagen barrier membrane and a natural bone mineral.
1) Preoperative probing indicating the presence of a deep pocket distal to the mandibular left molar. 2) Preoperative radiograph demonstrating the extent of bone loss.
3) Intraoperative view revealing a deep noncontained intrabony defect. 4) Following removal of granulation tissue and root planing, the defect is filled with Geistlich Bio-Oss®.
5) The grafting material and the surrounding alveolar bone are covered with a Geistlich Bio-Gide® Perio. 6) Minimal recession of the soft tissues and attachment gain and reduced PD measured 6mm and 7 mm respectively at 1 year.
Postoperative radiograph at 1 year reveals an almost complete fill of the intrabony defect.
