Advanced platelet-rich fibrin plus and osseous bone graft for socket preservation and ridge augmentation - A randomized control clinical trial

Objective

To compare the clinical and radiographic effectiveness of A PRF Plus as an adjuctive material to osseous bone graft in socket preservation and ridge augmentation.

Methods

Twenty patients with need to preserve extraction socket in non-molar sites planning for further prosthetic rehabilitation were divided into two groups. Test Group (Group A) was treated with A PRF Plus membrane and Sybograf plus ™ (70% HA and 30 %β TCP) bone graft. The Control Group (Group B) was treated with Sybograf plus ™ (70% HA and 30% βTCP) bone graft. Both groups had same socket preservation surgical technique.

Results

Both Group A and Group B showed significant improvement in clinical and radiographic parameters. Mean socket length, Vertical Resorption reduction in Group A was 1.48 whereas in Group B was 1.67 which is statistically significant. (p ​≤ ​0.05). Changes in Horizontal width reduction at 1,3, and 5 ​mm depth of the socket for both groups were not statistically significant. The Gain in socket fill for Group A and B 6 months postoperatively was 1185.30HU ± 473.21 and 966.60 HU ± 273.27 respectively. But intergroup comparison was not statistically significant. (p ​= ​0.17). There were no significant statistical differences in postoperative pain in Group A and Group B as subjects experienced moderate amount of pain. The assessment of post-operative swelling showed that only 30% subjects in Group A reported with swelling. Whereas 80% subjects in Group B complained of post-operative swelling.

Conclusion

The results of the present study proved utilisation of A PRF Plus as a promising adjunct to conventional regenerative therapy for socket preservation.

Autologous platelet-rich fibrin: can it secure a better healing?

OBJECTIVE

The aim of this study was to evaluate the efficacy of platelet-rich fibrin (PRF) in the healing of impacted mandibular third molar (M3) extraction sockets.

STUDY DESIGN

This study included 30 patients with bilaterally symmetric impacted M3 (N = 60) requiring transalveolar extraction. All patients were assigned numbers randomly; left-sided M3 patients with odd numbers and right-sided patients with even numbers were categorized into group A (test group), and the other side of the mouth was classified as "group B" (control group). Group A M3 extraction sockets received PRF, whereas group B sockets were closed without PRF. Patients were evaluated for pain and swelling on postoperative days 1, 3, 7, and 14. Bone healing was compared on postoperative weeks 8 and 16. Analysis of variance (ANOVA) and Tukey's multiple comparison tests were applied for statistical analysis.

RESULTS

A total of 30 patients, ages 18 to 40 years, participated in this study. The overall postoperative pain score (visual analogue scale [VAS]) and facial swelling percentages were lower for group A compared with group B (P < .05). Early bone healing was also evident on postoperative radiographs obtained at weeks 8 and 16 in group A (P < .001).

CONCLUSIONS

The use of autologous PRF aids in earlier and better wound healing in a controlled manner.
