Background
Necessity of keratinized tissues (KTs) for maintaining health around dental implants (DIs) remains as a controversial issue.
Purpose
The aim of this study was to investigate the effects of KT width (KTW) on peri‐implant tissues by evaluating peri‐implant clinical and inflammatory parameters.
Materials and Methods
Sixty DIs were included in this 6‐month longitudinal study. After classifying DI based on the presence of KTs at the buccal aspect as with adequate/inadequate KTW, DIs were randomly assigned into three study groups. In the first group, while free gingival graft (FGG) was performed, DIs in maintenance (M) group were followed up by standardized maintenance procedures at baseline, first, third, and sixth months as with DI with adequate KTW (Control). Clinical parameters, peri‐implant sulcular fluid (PISF) volume, PISF Interleukin 1β concentration, and bone loss were analyzed.
Results
Significant improvements in clinical and immunological parameters were noted only for FGG for the whole study period. Statistical differences detected between the treatment groups (FGG vs M) were for gingival index at all time points and for PISF volume at sixth month. For the other parameters evaluated, while lower values were observed for FGG, statistically no differences were noted between the groups.
Conclusions
Based on the results of this study, it can be suggested that FGG performed around DIs lacking KT is a reliable method, leading to significant improvements in clinical and inflammatory parameters. Further long‐term studies including more DIs are needed to clarify the role of KT on maintenance of DIs.
