In modern society to be confident in one’s appearance is an important issue, a topic which influences current periodontal trends. One treatment for which surgery aims to restore the patient’s aesthetic as well as comfort and dental function is the treatment of denuded root surfaces, also known as gingival recessions, one of several mucogingival plastic surgeries.

One treatment for which surgery aims to restore the patient’s aesthetic as well as comfort and dental function is the treatment of denuded root surfaces, also known as gingival recessions, one of several mucogingival plastic surgeries.
Clinical sites with recessions caused by false tooth brushing technique, show visibly healthy gingiva and cuneiform defects which are flat, clean and polished.
Over the years several techniques have been introduced for the treatment of gingival ,recession defects, these can be split into two main groups. Firstly there are pedicle soft tissue grafting procedures such as laterally sliding flaps, double papilla flaps, the coronally advanced flap and the modified tunnel technique. Secondly there are free soft tissue grafting procedures including soft tissue autografts, free connective tissue grafts and guided tissue regeneration.
This study investigates the treatment of multiple adjacent gingival recessions with a Coronally Advanced Flap (CAF) without releasing incision and a modified Microsurgical Tunnel Technique (MMTT).
The CAF is one of the most frequently used methods to cover gingival recessions. A further advancement, suggested in this study, is the performance of the CAF without vertical incision which could damage the blood supply to the graft from the surrounding tissue.
Another technique which avoids vertical incision is the Tunnel Technique. The MMTT used for this study is a simplification of the tunnel technique introduced by Azzi et al. in 2002. It suggests converting the full- thickness flap into a partial- thickness flap to ensure the grafted tissue receives adequate nutrition from the remaining connective tissue, periosteum and the outside flap.
The aim of this prospective, clinical trial will be to assess and compare the clinical performance of Coronally Advanced Flap and Tunnel Technique, in combination with a connective tissue graft, in the treatment of multiple recessions in terms of (I) reduction of gingival recession, (II) percentage of root coverage, (III) percentage of sites with complete root coverage and (IV) outcomes based on aesthetic, root sensitivity and general satisfaction.
