Five‐year evaluation of the influence of keratinized mucosa on peri‐implant soft‐tissue health and stability around implants supporting full‐arch mandibular fixed prostheses

Abstract

In patients exercising good oral hygiene and receiving regular implant maintenance therapy, implants with a reduced width of <2 mm of peri-implant keratinized mucosa were more prone to lingual plaque accumulation and bleeding as well as buccal soft-tissue recession over a period of 5 years.
