Title : Clinical evaluation of A PRF in treating RT1 gingival recession using the VISTA technique
Abstract:
Gingival recession presents both functional and aesthetic complications in dental practice. Vestibular Incision Subperiosteal Tunnel Access (VISTA) is a minimally invasive technique that has gained popularity in root coverage. This runs in tandem with the regenerative potential of Advanced Platelet-Rich Fibrin (A- PRF), which presents favourable results in the healing of soft tissues. A randomised clinical trial was conducted to determine the clinical effectiveness of combining the VISTA technique and A-PRF, versus the VISTA procedure and collagen matrix for Cairo Class I gingival recession.
Methods: Twenty-four systemically healthy subjects aged 21–47 years with single or multiple adjacent RT1 recession defects were selected and randomly assigned to two equal groups. VISTA with A-PRF was applied in the study group, while VISTA with collagen matrix was implemented in the control group. Clinical parameters—recession depth (RD), recession width (RW), gingival thickness (GT), width of attached gingiva (WAG), mean root coverage percentage (MRC%), and clinical attachment level (CAL)—were recorded at baseline, 3 months, and 6 months.
Results: The results indicated a significant improvement in all parameters for both groups, with the A-PRF group showing higher values for RD, RW, and MRC% (p < 0.001). In GT and WAG, no statistically significant differences between the groups were noted. CAL progressed more significantly in the A-PRF group over time. Conclusion: The findings support the notion that the integration of VISTA with A-PRF is a superior and patient-satisfying option for RT1 gingival recession treatment, exhibiting higher clinical efficiency compared to collagen matrix.
