Influence of the keratinized mucosa on the stability of peri‐implant tissues and brushing discomfort: A 4‐year follow‐up study

The findings of the present study indicate that KM width had an effect on MBL, plaque accumulation, tissue inflammation, and brushing discomfort over the studied period. Thus, the presence of a KM ≥ 2 mm around implants appears to have a protective effect on peri-implant tissues.
