چکیده

There is a great deal of controversy in the literature about the importance of keratinized gingiva around dental implants and the amount, if any, required for implant health. Some studies conclude that peri-implant health could be maintained even in the absence of keratinized gingiva providing adequate oral hygiene is employed [1]. Other studies suggest that areas of minimal keratinized gingiva have decreased tissue resistance allowing plaque accumulation, which increases the risk of gingival inflammation, marginal bone loss, and increased gingival recession [1]. We hypothesize that implants surrounded by less than 2mm of keratinized gingiva are more susceptible to failure due to decreased resistance of the tissues to bacterial infiltration, leading to increased tissue breakdown, increased probing depths surrounding the implants, increased bleeding upon probing, and increased bone loss. The purpose of this study is to determine whether a minimum width of 2mm of keratinized gingiva around dental implants is necessary for the health and stability of the surrounding soft and hard tissues of the periodontium. Knowing this will help clinicians determine whether or not gingival augmentation to increase the amount of keratinized gingiva is required prior to implant therapy.

Free Gingival Grafting to Increase the Zone of Keratinized Tissue around Implants

Purpose: The importance of an adequate width of attached gingiva around periodontally affected teeth has been well-documented. However, there is no consensus regarding the relationship between the width of keratinized tissue and the health of peri-implant tissues. Clinicians in general prefer to provide enough keratinized mucosa around dental implants for long-term implant maintenance. There ar...
