Utilizzo di una matrice xenogenica di collagene nell’aumento dei tessuti molli peri-implantari. Use of a xenogenic collagen membrane in peri-implant soft tissue augmentation

OBJECTIVES Over the years, several techniques have been proposed for peri-implant soft tissue augmentation in order to improve keratinized mucosa width (KMW) and gingival thickness (GT). The aim of this study is to present the one year follow-up results of a xenogenic collagen matrix in augmentation procedures. MATERIALS AND METHODS Ten patients were enrolled in this prospective study: one dental implant was placed in the maxilla in the premolar area and, at the time of second stage surgery, the matrix was inserted. KMW and GT were recorded at 1, 3, 6 and 12 months. RESULTS Mean values of KMW and GT were respectively 1.47±0.23 and 1.35±0.32 mm at baseline, while after 1 year mean values of 4.17±1.98 and 4.12±2.12 mm were recorded. CONCLUSIONS According to the results of this work, KMW and GT were significantly augmented, demonstrating the clinical advantages of this new membrane.
