Root Coverage with Platelet-Rich Fibrin in Miller's Class I, III, and IV Gingival Retractions.

Coronally advanced flap (CAF) with connective tissue graft (CTG) is considered as the most predictable method to treat Miller's Class I and II gingival recessions (GR). However, due to the patient's postsurgical discomfort, the difficulty of finding a donor with an adequate tissue thickness, the high costs of acellular dermal substitute among others, the platelet concentrates have been found to scaffold alternative to replace CTG as a part of the CAF treatment for GR. Nevertheless, according to the recent literature, the evidence of success in Class III and IV has been limited for CAF and platelet-rich fibrin (PRF). The purpose of this report is to present a case of multiple Miller's Class III and IV GR treated with CAF and PRF where the potential of PRF to increase gingival thickness and clinical attachment level, and improve soft-tissue healing and clinical appearance was corroborated.
