The purpose of this study is to evaluate the stability of the free gingival graft dimensions around dental implants and to compare three-dimensional changes according to smoking status. Its primary goal is to provide an answer to: Is this grafting procedure stable around dental implants? Are there any differences in tissue stability between smoker and non-smoker patients? Our study consists of 2 groups: The first group includes smoker patients who need free gingival grafts around their dental implants (n=16). The second group includes non-smoker patients who need free gingival grafts around their dental implants (n=16). Clinical measurements will be recorded at the baseline, 1st month, 3rd month, and 6th month of the study. An intraoral digital scanner will be used to measure the dimension changes of the graft at the baseline, after the surgery, 1st month, 3rd month, and 6th month of the study. Wound healing will be evaluated on postoperative days 10, 1 month, 3 months, and 6 months. Visual Analog Scale will be used to measure postoperative pain, and the number of painkillers taken will be recorded.
