Papillary Coronal Anchorage Technique for Periodontal Reconstruction of the Infrabony Defect and Interdental Papilla:...

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 predominantly target 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 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 coronally anchoring the tunnel-like flap using sutures, reconstruction of both the infrabony defect and the interdental papilla were achieved. The papillary coronal anchorage technique is effective, as it enables the simultaneous reconstruction of both the infrabony defect and the interdental papilla.
