2004 • EDWARD PAT ALLEN • ALLEN MICROSURGICAL ELEVATOR
The tunnel technique, originally known as the pouch technique, was introduced by Raetzke in 1985. The aimwas to avoid any kind of releasing incisions, as described by Raetzke, this technique’s main characteristic was the insertion of an autologous connective tissue graft in a pouch that was created in the buccal soft tissues around the exposed root surface by means of a split thickness flap preparation. Favorable aesthetic outcomes, as well as the simplicity of this approach, were the main reasons for its broad acceptance in clinical periodontology. Since this technique had been originally proposed for single tooth defects only, Allen A. L. demonstrated the use of the pouch technique at multiple adjacent gingival recession defects (Allen, 1994). In 1999 Blanes R. J. and Allen E. P. published a technique which combined a tunnel with lateral pedicle flaps to completely cover a CTG. Afterwards, Edward Patrick Allen introduced a coronally positioned tunnel technique that was difficult to perform with conventional instruments so he partnered with Hu-Friedy in the development of specific microsurgical designs for improving performance. He continues to promote these instruments and his technique worldwide.
