Apical horizontal incision with periosteum graft wall technique for periodontal regeneration: A case study

The apical horizontal incision combined with periosteum graft could successfully save a tooth with severe bone destruction and a non-contained periodontal defect. The importance of wound stability on the papillae area was achieved with the vestibular approach with application of the room concept. This method would be beneficial to improve the periodontal prognosis of a severely periodontally compromised tooth.
