Effectiveness of vestibular incision subperiosteal tunnel access technique in the treatment of multiple adjacent gingival recession defects: A systematic review.

OBJECTIVE

To investigate the effectiveness of Vestibular Incision Subperiosteal Tunnel Access (VISTA) technique over other root coverage (RC) procedures for treating Millers Class I and II multiple adjacent gingival recession defects (MAGRD).

METHODS

Patient, Intervention, Comparison, and Outcome question was established, and a literature review was carried out across PubMed, Cochrane Libraries, EMBASE, and hand-searched journals till April 2023 to identify the clinical research on the effectiveness of the VISTA Technique for RC procedures. Only randomized controlled trials (RCTs) with a minimum of 6 months' follow-up were considered. The outcomes assessed were complete RC (CRC), width of keratinized gingiva, and gingival thickness.

RESULTS

A total of 30 articles were retrieved and ultimately 7 RCTs that met the inclusion criteria were incorporated into the systematic review. VISTA with biomaterials showed significant improvements in all the treatment outcomes over other RC procedures. Specifically, VISTA + subepithelial connective tissue graft (CTG)/CTG achieved an average CRC of 93.95%, along with significant increase in other parameters. In addition, biomaterials such as platelet concentrates, collagen membrane, Bioguide enhanced GEM21S, and Acellular dermal matrix proved viable alternatives producing similar outcomes.

CONCLUSION

VISTA technique is an effective procedure for treating MAGRD in terms of achieving CRC over other RC procedures. In addition, the use of biomaterials further enhances the treatment outcomes.
