The reconstruction of interproximal papilla around implants is considered challenging with limited predictability due to the anatomical constraints and reduced blood supply to the interproximal area. This report introduces a minimally invasive tunneling approach, assisted by an operating microscope, to augment interproximal papillae and improve soft tissue contours. Four cases are included: Cases 1 and 2 demonstrate soft tissue grafting around adjacent implants, performed either during the second stage or after provisionalization, while Cases 3 and 4 address implant-pontic scenarios. After conditioning the peri-implant tissues using provisionals, all cases achieved satisfactory outcomes, maintaining stability over a period of six to nine years. The described microsurgical tunnel technique, with the combination of buccal and interproximal subepithelial connective tissue graft, appears to be a promising approach for reconstructing peri-implant papillae with reliable long-term stability.
