Is the presence of keratinized mucosa associated with periimplant tissue health? A clinical cross-sectional analysis

“…But still, there is a lack of evidence whether KM has an impact on periimplant tissue health and periimplant bone level, respectively [27,29]. The main reason for this limitation is the heterogeneity in study designs and data extraction; consecutively, there is a lack of a synoptic statistical analysis [34].…”

“…Current studies with moderate examination periods up to 5 years reported that higher plaque accumulation and gingival inflammation were associated with the absence of KM [25,26]. This statement is supported by several systematic reviews [27-29]. Dental implants with less than 2 mm of KM seem to be more prone to recession and alveolar bone loss, measured between the crestal bone level and a reference point on the implant surface [26,30].…”

Various Techniques to Increase Keratinized Tissue for Implant Supported Overdentures: Retrospective Case Series

“…Several studies have reported increased gingival and plaque index scores, mucosal recession, and marginal bone resorption in areas around implants with less than 2 mm of keratinized tissue [4, 8, 13–16]. Conversely, some authors have claimed that, with adequate plaque control, peri-implant tissues can be maintained in a healthy state with a minimum amount of keratinized tissue [6–9].…”

Taller 5 - Peri-implantitis

“…Ausencia de encía queratinizada: La deficiencia de mucosa queratinizada alrededor de los implantes, parece estar relacionada a parámetros clínicos de inflamación y a la acumulación de biolfim. Sin embargo, en base a la evidencia disponible actualmente, la cantidad de mucosa queratinizada en relación al desarrollo de la peri implantitis permanece controversial (28,29) .…”
