This combined tunneling instrument has sharp curette-shaped working ends. The newly developed tunneling knife strongly minimizes the risk of perforation with buccal split-thickness flaps. Moreover, its use ensures improved wound healing and can even provide improved esthetic results. The straight tip is mainly used in the maxilla, especially where a tunneling technique is required for larger areas of keratinized gingiva. The angled tip can be used to prepare a tunnel in the mandible, especially in the buccal region. In addition, the angulation allows surgeons to twist the instrument so they can make incisions into interproximal areas.
