2015 • GILES DE QUINCEY • MICRO TUNNELLING INSTRUMENT
The idea for the tunneling instrument evolved in the late 90‘s when De Quincey started (mis)using Hirschfeld files to release tissue laterally, using the envelope technique for coronally positioned flaps in combination with CTG for recession treatment, as described by Zucchelli. He then modified the Hirschfeld files by removing the teeth/ serration, followed by polishing the surface. This resulted in an instrument that is not sharp, but because of its small dimensions, it was able to separate tissues, specifically the marginal gingiva from the underlying bone/periosteum. This design in combination with the slick, black coating of the current instrument resulted in an instrument that is ideal for tunneling thin tissues, typically seen in patients with a thin periodontal biotype presenting with severe gingival recession. The black color not only reduces glare when using high magnification, it also increases the visibility of the instrument through the tissue and therefore creates an extra element of control through visual feedback during tunneling. This feedback reduces the risk of perforation of thin tissues when tunneling.
