Interproximal Tunneling with a Customized Connective Tissue Graft: A Microsurgical Technique for Interdental Papilla Reconstruction.

Interdental papilla reconstruction is one of the most challenging clinical procedures in periodontal plastic surgery. Several surgical approaches have been proposed but have varying degrees of success. It has long been acknowledged that the narrowness of the interdental papilla and the limited blood supply are major impediments to achieving predictable outcomes. Advances in microsurgery could offer an opportunity to overcome these anatomic and biologic barriers. The authors propose an original microsurgical technique based on interproximal tunneling combined with utilization of a customized tissue graft for interdental papilla reconstruction.
