Different types of blood products have been introduced in dental medicine since 1990. Platelet-rich fibrin (PRF) isan autologous blood product that can improve tissue healing and finds wide clinical application. The application of PRF in dental medicine has gained popularity due to its effect on periodontal regeneration, wound healing, and anti-inflammatory effects. PRF can fulfill different purposes in periodontal treatment, including serving as an alternative to soft tissue graft. A common problem in periodontal treatment is the minimum amount of attached gingiva. In terms of attached and keratinized gingiva, the stable periodontal tissue provides long-term stability regarding clinical interventions such as creating a stable zone of attached gingiva.Case presentation: A 62 years old female patient has a significant complaint of receding gum in the area of lower central incisors, accompanied by pain while brushing and inability to maintain proper self-performed oral hygiene.
Conclusion: After 7,5 years of follow-up, the results show satisfactory results in augmentation of the attached gingiva and deepening the oral vestibule. The application of an A-PRF membrane could be used as an alternativeto free gingival graft in non-demanding periodontal cases.
