The tunnelling instruments are used in microsurgery for the preparation of split- and full-thickness flaps for subsequent ridge augmentations and for repairs of gingival defects caused by receding gums. The precisely manufactured working ends enable precise opening of the gingiva and thus help prevent large flap openings. Tips are square and sharp to provide greater surface area and easy detachment of periosteum from bone. The design and angle of the working tips significantly facilitates preparation in convex areas. These Set of 6 elevators are designed to create a sub periosteal tunnel beneath mucosa, using a vestibular access. The VISTA elevators allow for efficient tunnel elevation in the vestibular region, under gingival margins, and under interproximal tissues.
