Clinical comparison of using free gingival graft in patients presenting inadequate keratinized mucosa around dental implants in smokers and non-smokers: A controlled clinical study
Project no. 354 · Status: Kapanmış · 2016
Summary
Aim: The aim of the present study was to investigate the effect of smoking on healing of free gingival graft (FGG) around dental implants and donor site. Methods: Twelve non-smoker and eight smoker patients presenting inadequate keratinized mucosa (KM) around implants in posterior area were included in the study. Individuals stents were prepared for all patients. All patients received FGG with standardized dimensions. Vertical dimension of KM and vestibule sulcus depth was measured using individual stent. Tissue thickness of the recipient and donor site was measured by ultrasonic device and transgingival probing. All measurements were performed at baseline, 30 and 90 and 180 days. Parametric and non-parametric statistical analyses were performed. Results: Vertical dimension of KM and vestibule sulcus depth was significantly increased in both study groups at sixth month compared to baseline (p< 0,05). There was no significant difference between smokers and non-smokers in vertical dimension of mucosa and vestibule sulcus depth (p> 0,05). The thickness of KM in the recipient site significantly increased at first, third and sixth months compared to baseline in both groups (p< 0,05). The FGG area significantly decreased at first, third and sixth months compared to baseline in both groups (p< 0,05). The shrinkage of FGG significantly higher in smokers than non-smokers at sixth months (p< 0,05). Conclusions: Smoking does not seem to be an important factor for the changes in vertical dimension of KM and tissue thickness following FGG around dental implants with inadequate KM. However smoking might affect the FGG area.
