The long-term efficacy of adequate keratinized mucosa (>2 mm) in dental implants is controversial. Peri-implant plastic surgeries are currently used because they increase width (KMW), helping to regain peri-implant health and maintaining it over the long-term. We present clinical findings using free-gingival-graft (FGG) free-periosteal-graft (FPG) techniques surgery for implant rehabilitation patients. included 20 patients with indications inadequate KMW (KMW < 2 mm postimplantation) maxilla...

Abstract – Conservative solutions for the restoration of a single edentulous space in anterior maxilla present an esthetic challenge to clinician. A 45‐year‐old male patient whose right upper central tooth was planned be extracted referred our clinic conservative, rapid, and economic treatment. After radiographic clinical examinations, it decided that which should used its own area. The splinted adjacent teeth with aid grooves fiber‐reinforced composite (everStick ® , StickTech Ltd., Turku,...
