Treatment of Multiple Gingival Recessions Using Vestibular Incision Subperiosteal Tunnel Access with Platelet-rich Fibrin: Two Cases Reports

초록

Treatment of multiple gingival recession defects is usually more challenging than that of single gingival recession. Various techniques for the treatment of multiple gingival recession have been established. Recently, vestibular inci sion subperiosteal tunnel access (VISTA) technique has been considered to exhibit high predictive ability. Connec tive tissue graft (CTG) has also been considered a gold standard technique owing to its high predictability of root coverage. However, this technique requires a suitable donor site and has clinical disadvantages, such as additional pain. Thus, in this case presentation, platelet-rich fibrin (PRF) was used as an alternative material for CTG along with VISTA. We herein report cases of two patients with Miller’s class I and III multiple gingival recession defects, respectively. These patients underwent VISTA along with the use of a PRF membrane. They were followed up for 12 months postoperatively, and their clinical parameters, including probing depth, depth of gingival recession, clini cal attachment level, and width of attached gingiva at baseline and at 2, 6, and 12 months postoperatively, were as sessed. The patient with class 1 recession defects exhibited a significant amount of root coverage, which remained stable during the follow-up period. Whereas the patient with class 3 recession defects had lesser amount of coverage compared to class 1 patient. The partial coverage observed may be attributed to not only anatomical factors but also the technique-sensitive nature of the procedure. Considering these results, the use of VISTA along with PRF is a vi able option for treating gingival recession, as it does not cause discomfort to patients. However, various factors need to be considered during the surgical procedure.
