A comparative study of two-root coverage techniques for treatment of multiple gingival recessions: a systematic review of the literature
Objectives: Gingival recession is both unpleasant and unaesthetic. Meeting the esthetic and functional demands of patients with multiple gingival recessions remains a major therapeutic challenge.
The aim of this literature review is to confirm the effectiveness and the predictability of Zucchelli’s technique and tunnel technique with sub-epithelial connective tissue graft (SECTG) for root coverage of multiple gingival recessions.
Methods: An electronic search on Pubmed, the Cochrane database and hand-searched journals, for randomized controlled clinical trials, controlled clinical trials and case series that involved at least six months' follow-up, was conducted to identify clinical studies investigating both techniques for root coverage treatment.
Results: 28 studies were included in this literature review; only 25 studies were interested in one or the other of these two techniques, two Meta-analyzes highlighted them and only a recent study compared them directly.
The overall calculated root coverage (RC) of Zucchelli’s technique and tunnel technique for multiple gingival recessions (GRs) was 82.75%±19.7% and 87.82%±16.52% respectively.
Superior results were found in Miller Class I and II gingival recessions.
Outcomes may be enhanced by gingival biotype, flap preparation and microsurgical approach.
Both techniques had comparable root coverage (RC), clinical attached level (CAL) and keratinized tissue (KT) gain when varying combinations of graft materials were evaluated. Although Zuccheli’s technique showed superior outcomes when sub-epithelial connective tissue graft was used in both techniques.
Conclusions: Periodontal plastic surgeries for the treatment of multiple gingival recessions require a conscientious follow-up and patient's compliance.
Zucchelli’s technique and tunnel technique with sub-epithelial connective tissue graft (SECTG) actually allow very satisfactory percentages of complete and average root coverage, although limited evidence is still available when comparing the two techniques.
So new randomized, long term, statistically and as objectively as possible studies comparing directly these two techniques will be needed to rigorously determine the best periodontal plastic surgeries that meet the mutual expectations of patients and periodontists.
