Width of the Periimplant keratinized Mucosa
Clinical and experimental studies have failed to support the concept of an "adequate width" of keratinized tissue adjacent to natural teeth for the maintenance of periodontal health. Implant research has also focused on the necessity of the presence of keratinized mucosa around oral implants.
The absence of the keratinized mucosa around implants seems to increase the susceptibility of plaque induced periimplant disease. However, in the presence of good oral hygiene, the nature of the mucosa may have little influence on the long term survival of the implants. But, it is important to note that in case of suboptimal oral hygiene there is greater tissue damage around implants within alveolar mucosa than around implants within keratinized tissue. Therefore it is an important parameter to take note of.
