A minimal invasive periodontal surgery around implant 16 décembre 2019
Various soft tissue manipulations during bone augmentation surgeries, in particular in order to obtain primary and watertight closure of the flaps, weaken the soft tissues. This modification is accompanied by a severe loss of keratinized tissue (KT) and vestibular depth and thereby with displacement of the mucogingival line. The aesthetic and biological integration of implant-prosthesis is directly related to the presence of favorable mucosal conditions.
This case series study was performed to evaluate the quantity and quality of keratinized tissues in 13 sites following the combination of the strip gingival graft technique described by Urban with the use of a xenogeneic collagen matrix over a period of 36 months.
