Papillary Coronal Anchorage Technique for Periodontal Reconstruction of Infrabony Defect and Interdental Papilla: A Case Report.

Esthetic issues and phonetic disturbances frequently occur after periodontal regeneration of the anterior teeth, even if treatment is supposed to be successful. Conventional regenerative techniques are predominantly targeted at infrabony defects and often inadequately address the loss of the interdental papilla. This study introduces the papillary coronal anchorage technique, a novel modified tunnel surgical procedure, to facilitate the reconstruction of the interdental papilla. This method allows for coronal movement of the entire interdental papilla without incisions at the papilla to facilitate primary wound healing. Using a combination of bone grafts and recombinant human fibroblast growth factor 2 and anchoring the tunnel-like flap coronally using sutures, we successfully achieved a reconstruction of the infrabony defects as well as the interdental papilla. The papillary coronal anchorage technique is effective as it enables the simultaneous reconstruction of both the infrabony defect and the interdental papilla.
