Flap Thickness Upon Root Coverage With the Use of Acellular Dermal Matrix

OrACell has been tested as a barrier in bone regenerative procedures showing promising results in new bone formation after socket preservation, but no data is available on root coverage procedures. Moreover, it has been suggested that keratinized tissue width (KTW) ≥2mm and gingival thickness (GT) ≥1.2 mm at 6 months of the surgical procedures are two important predictors for long term stability of gingival margin Therefore, it was hypothesized that soft tissue thickness and keratinized tissue width may influence the percentage of root coverage. By means of a prospective case series (12 patients in total), the aim is to study the performance of the OrACell dermal matrix in the treatment of multiple and adjacent gingival recessions, determining the amount of complete root coverage obtained at 6 months of follow-up. At the same time, it is intended to evaluate the effect of initial gingival thickness, by means of digital scanning, upon the success of root coverage procedure with OrACell.
