[Enlargement of keratinized peri-implant mucosa at the time of second stage surgery (re-entry)].

A tightly attached keratinized mucosa around endosseous dental implants is believed to be protective against peri-implant bone loss. Tension caused by buccal frena and mobile non keratinized mucosa is to avoid. This case report documents the optimization of peri-implant mucosal conditions in the upper and lower jaw. At the time of second stage surgery (re-entry) at submucosally osseointegrated dental implants an enlargement of keratinized mucosa and a thickening of soft tissue was obtained administrating a vestibuloplasty combined by a free gingival graft or a vestibuloplasty combined by an apically moved flap.
