Brief Summary

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

Outcome Measures

Primary Outcomes (2)

  • Peri-implant keratinized mucosa width

    To measure peri-implant keratinized mucosa width of subgingival and submucosal injection of injectable platelet-rich fibrin in patients with inadequate peri-implant soft tissue phenotype at 1-year follow-up.

    1-year follow-up of all implants

  • Peri-implant mucosa thickness

    To measure peri-implant mucosa thickness of subgingival and submucosal injection of injectable platelet-rich fibrin in patients with inadequate peri-implant soft tissue phenotype at 1-year follow-up.

    1-year follow-up of all implants

Secondary Outcomes (1)

  • Pink esthetic score

    1-year follow-up of all implants

Study Arms (2)

Thin phenotype

OTHER

Mucosa thickness is less than 1 mm and the visibility of the probe in the sulcus is high.

Procedure: Platelet rich fibrin

Thick phenotype

OTHER

Mucosa thickness is greater than 1 mm and visibility of the probe in the sulcus is low.

Procedure: Platelet rich fibrin

Interventions

The 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.

Also known as: Injectable plateler rich fibrin
Thick phenotypeThin phenotype
