Multiple gingival recessions treated using the tunnel technique with a collagen matrix
Numerous techniques have been described for root coverage such as CAF (coronally advanced flap), pedunculated flaps, free gingival grafts and the tunnel technique, using either the simple flap or xenografts, allografts or autologous connective grafts, depending on the clinical case.
In this case a 39 year old female patient presented herself with a white cleft (traumatic fissure at the apex of the recession with loss of attachment) on tooth #22 FDI (#10 US). A modified tunnel technique was used with a double papilla technique de-epithelializing the margins of the white cleft so that the two flaps could be sutured together.
At the follow-up appointment, it was noted there was some cervical discoloration due to a small portion of the root surfaces still visible in both the upper and lower arches. However, a substantial amount of root coverage was obtained.
