Teeth loss are usually associated with alterations of extraction sockets result in obviously absorbed alveolar ridges and are often accompanied with soft tissue atrophy such as narrow keratinized tissue and a shallow vestibule. Lack of peri-implant keratinized tissue is a potential risk to peri-implant diseases. Although the role of width of KM in maintaining peri-implant health is a controversial topic, the majority of high-level evidence has suggested that a minimum KM width (KMW) of 2 mm around the dental implants is critical to maintain peri-implant health and the long-term survival of dental implants.
