Evaluation of PRF Membrane with Coronally Advanced Flap with and without Vertical Releasing Incisions for the Treatment of Gingival Recessions.

AIM: The aim of the current study was to compare the esthetic results for subjects with Miller Class I and II gingival recession (GR) abnormalities using platelet-rich fibrin (PRF) membrane with coronal advanced flaps (CAFs) with and without vertical releasing incisions (VRIs; the envelope-type flap and the flap with VRIs).

MATERIALS AND

METHODS

Seven defects from each of the test and control groups made up of fourteen defects total. In the test group, PRF + CAF was performed without VRI, while in the control group, VRI was used. Gain in root coverage was the main result, with secondary results including papillary bleeding index (PBI), plaque index (PI), relative gingival margin level, relative attachment level, probing pocket depth, recession depth, width of keratinized gingiva (WKG), and gingival thickness. After 3 months of therapy, a clinical evaluation was conducted.

RESULTS

No significant difference was observed between the two groups in terms of recession reduction (2.08 ± 0.5 vs 1.91 ± 0.66 mm), clinical attachment level (CAL) gain (2.08 ± 0.5 vs 1.91 ± 0.66 mm), and increase in WKG (2.66 ± 0.88 vs 2.58 ± 0.51 mm) for test and control groups, respectively.

CONCLUSION

For the treatment of GR, both groups are efficient. However, the CAF + PRF without VRI group showed higher patient compliance and lower postoperative morbidity.

CLINICAL RELEVANCE: The PRF membrane with CAF with or without VRI provide effective treatment option for GR. CAF + PRF without VRI is easy to perform and has less postoperative complications.
