Abstract
BACKGROUND

Collagen membrane and platelet-rich fibrin (PRF) have emerged as vital biomaterials in the field of periodontal regeneration. Minimally invasive techniques are being preferred by most periodontists, as it is patient compliant with fewer post-surgical complications as compared to conventional surgical techniques. Thus, in this study we have evaluated the effect of injectable PRF (i-PRF) with collagen membrane compared with collagen membrane alone using vestibular incision subperiosteal tunnel access (VISTA) technique for gingival recession coverage.

AIM

To compare the efficacy of VISTA using collagen membrane with collagen membrane soaked in injectable PRF for gingival recession coverage.

METHODS

A split mouth randomized controlled clinical trial was designed;13 subjects having at least 2 teeth indicated for recession coverage were enrolled in this study. The sites were randomly assigned to control group (VISTA using collagen membrane alone) and the test group (VISTA using collagen membrane with i-PRF). The clinical parameters assessed were pocket depth, recession depth (RD), recession width (RW), relative attachment level, keratinised tissue width (KTW), keratinised tissue thickness (KTT), and percentage root coverage.

RESULTS

RD showed a statistically significant difference between the test group at 3 mo (0.5 ± 0.513) and 6 mo (0.9 ± 0.641) and the control group at 3 mo (0.95 ± 0.51) and 6 mo (1.5 ± 0.571), with P values of 0.008 and 0.04, respectively. RW also showed a statistically significant difference between the test group at 3 mo (1 ± 1.026) and 6 mo (1.65 ± 1.04) and the control group at 3 mo (1.85 ± 0.875) and 6 mo (2.25 ± 0.759), with P values of 0.008 and 0.001, respectively. Results for KTW showed statistically significant results between the test group at 1 mo (2.85 ± 0.489), 3 mo (3.5 ± 0.513), and 6 mo (3.4 ± 0.598) and the control group at 1 mo (2.45 ± 0.605), 3 mo (2.9 ± 0.447), and 6 mo (2.75 ± 0.444), with P values of 0.04, 0.004, and 0.003, respectively. Results for KTT also showed statistically significant results between test group at 1 mo (2.69 ± 0.233), 3 mo (2.53 ± 0.212), and 6 mo (2.46 ± 0.252) and the control group at 1 mo (2.12 ± 0.193), 3 mo (2.02 ± 0.18), and 6 mo (1.91 ± 0.166), with P values of 0.001, 0.001, and 0.001, respectively. The test group showed 91.6%, 81.6%, and 67% root coverage at 1 mo, 3 mo, and 6 mo, while the control group showed 82.3%, 66.4%, and 53.95% of root coverage at 1 mo, 3 mo, and 6 mo, respectively.

CONCLUSION

The use of minimally invasive VISTA technique along with collagen membrane and injectable form of platelet-rich fibrin can be successfully used as a treatment method for multiple or isolated gingival recessions of Miller’s class-I and class-II defects.

Core Tip: The use of minimally invasive vestibular incision subperiosteal tunnel access technique, along with collagen membrane acting as scaffold and chemoattractant with added benefit of injectable form of platelet-rich fibrin has the capacity of releasing more growth factors and regenerative cells responsible for tissue regeneration, can be successfully used as a treatment method for multiple or isolated gingival recessions of Miller’s class-I and class-II defects.
