Entire Papilla Preservation Technique with Recombinant Human Fibroblast Growth Factor-2 and Autogenous Bone Grafting in the Treatment of Isolated Non-Contained Intrabony Defect: Case Report of a 5-Year Follow-Up.

Abstract

Regenerative periodontal surgery is an effective procedure for the treatment of intrabony defects. Various flap designs preserving the defect-associated interdental papilla have been proposed to improve early wound stability. This case report describes the long-term results of a regenerative treatment in severely compromised mandibular canine using entire papilla preservation technique. Surgical access was provided by a single buccal vertical incision without any papilla incision. Combination of autogenous bone harvested from the same surgical site and recombinant human fibroblast growth factor-2 was applied to non-contained intrabony defect following the granulation tissue removal. Surgical site was closed with single interrupted sutures. The clinical outcomes and 5-year stability of pocket closure with no increase in gingival recession show the potential of entire papilla preservation technique with the use of combined biomaterials.
