Three-Dimensional Volumetric Analysis of Multiple Gingival Recession Defects Treated by the Vestibular Incision Subperiosteal Tunnel Access (VISTA) Procedure
Gil, Alfonso / Bakhshalian, Neema / Min, Seiko / Nart, José / Zadeh, Homayoun H.
This study sought to evaluate gingival volume changes following root coverage with the vestibular incision subperiosteal tunnel access (VISTA) procedure. Pre- and postoperative surface scans of 21 patients (154 teeth) treated with VISTA using various graft materials were digitally superimposed to quantify volumetric changes. A linear gingival thickness gain of approximately 1 mm and volumetric gain of 5.47 mm3 were achieved. A negative correlation was found between linear thickness gain and root prominence. The thickness achieved was not different with various graft materials. Since gingival thickness has been identified as an important predictor of periodontal root coverage, the methodology described in the present study, along with the identification of predictors of outcome, has important therapeutic implications.
