Effect of Keratinized Mucosa on Peri-implant Health

The study will be conducted in Faculty of Dentistry, Kutahya Health Sciences University . The patients who applied to the Department of Periodontology, received dental implant treatment, and required routine follow-up for the maintenance of peri-implant health will be included. Clinical and radiographic examinations will be performed at baseline (prothesis delivery) and at the end of the 3rd, 6th month, 1st year following the prosthetic loading. During clinical examination probing depth (PD), modified plaque index (mPI) and modified bleeding index (mBI) measurements will be evaluated with the Williams periodontal probe. These measurements will be taken at four points of the implant (mid-buccal, mesio-buccal, disto-buccal and mid-lingual) and these four measurements will be averaged for each implant. In addition, the amount of keratinized mucosa (KM) in the implant sites will be evaluated by measuring the mucosal margin and mucogingival junction on the vestibular surface with the same probe. After clinical examination, a periapical radiograph will be taken using a parallel technique to determine marginal bone loss surrounding the implant. The distance between the implant neck and the most coronal part of the alveolar crest will be measured on the mesial and distal surfaces for each implant on the obtained radiographs and the average of the two measurements will be taken. The parameters checked during clinical and radiographic examination will be compared between patients with or without keratinized mucosa and whose keratinized mucosa has been increased by free gingival graft.
