Abstract
Abstract A new attachment procedure based on retardation of epithelial downgrowth was used for the surgical treatment of 88 intrabony periodontal defects. Split flaps were made at the vestibular and oral aspect of the intrabony defect leaving a layer of connective tissue on the bone and corresponding to the missing bony walls. Granulation tissue was removed from the defect and the root surface planed. After transplantation of autogenous cancellous bone grafts from edentulous ridges, the defect was covered with a free palatal graft which was sutured to the adjacent, attached gingiva and underlying periosteum. The grafted area was covered with telfa and Coe pack was applied for 1–2 weeks. This procedure and a modification of it resulted in a markedly greater zone of new attachment when compared with traditional flap surgery. Residual pockets deeper than 3 mm were found in only 10 per cent of the defects treated by the soft tissue grafting technique.
