About this trial
An inadequate amount of peri-implant soft tissue results in more plaque accumulation around the implants, peri-implant mucositis, marginal bone loss, mucosal recession, and/or attachment loss. In the literature, there are studies evaluating the application of injectable platelet-rich fibrin to the gingiva and oral mucosa around teeth, but injectable platelet-rich fibrin application around implants has not been encountered. This study aimed to evaluate the effect of subgingival and submucosal application of injectable platelet-rich fibrin on peri-implant soft tissue phenotype in patients with inadequate peri-implant soft tissue phenotype.The study will include 80 systemically healthy and non-smoking patients/implants older than 18 years of age with insufficient peri-implant keratinized mucosa width and mucosal thickness who applied to Kütahya University of Health Sciences, Faculty of Dentistry, Department of Periodontology. There are two study groups according to peri-implant mucosa phenotype: Thin phenotype and thick phenotype. All patients will undergo the same procedure of injectable platelet-rich fibrin application
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
be over 18 years old

Patients who do not smoke or who smoke less than 10 cigarettes
Peri-implant keratinized mucosa width less than 2 mm

Trial design
Parallel
Treatments tested in this trial
Platelet rich fibrin
Procedure/SurgeryThe injectable platelet rich fibrin will be integrated into the tissue by subgingival and submucosal application to the keratinized gingiva of the implant sites with insufficient peri-implant soft tissue phenotype. Then, the prepared injectable platelet rich fibrin will be injected into the mucogingival junction apical to the keratinized gingival site. This procedure will be repeated 3 times in total, 1 time in 30 days for 3 months.

Secondary outcomes
Pink esthetic score
To measure the effect of subgingival and submucosal injectable platelet-rich fibrin application on the pink aesthetic score by the patient and physician in patients with inadequate peri-implant soft tissue phenotype.
