Pedicle Flap Designs for Soft Tissue Conditioning in the Therapy of Peri-implantitis

Keratinized mucosa (KM) is regarded as a key factor in peri-implant health. A lack of KM has been associated with discomfort, higher plaque accumulation, and mucosal inflammation. Persistent inflammation might lead to progressive peri-implant bone loss. Several approaches to manage peri-implantitis have been advocated. Despite the effectiveness shown by surgical therapeutic modalities, soft tissue conditioning seems pivotal for long-term peri-implant health and stability. Free epithelial grafts have been demonstrated to efficiently augment the band of KM. Nevertheless, morbidity, dynamic soft tissue changes, and longer healing periods are shortcomings to be considered. The purpose of this technical note is to provide an alternative therapeutic modality for the surgical management of peri-implantitis combined with simultaneous soft tissue conditioning by means of pedicle flaps. Three main clinical scenarios are provided to conceive pedicle epithelial or connective tissue flaps, combined or not with collagen matrices, as predictable approaches to augment KM in the surgical therapy of peri-implantitis.
