ABSTRACT
BACKGROUND: This clinical study investigates platelet-rich fibrin's (PRF) impact on dental implant stability, addressing global oral health challenges and limitations of traditional methods. Emphasizing osseointegration's pivotal role, the study explores PRF's potential in enhancing implant stability, assessing it through resonance frequency analysis (RFA) and implant stability quotient (ISQ). The hypothesis suggests PRF may improve both primary and secondary stability, aiming to uncover clinical benefits in dental implant procedures Materials and methods: The study involved 24 subjects from the Department of Periodontics outpatient clinics with a meticulously designed methodology. This included a pre-surgical protocol with oral prophylaxis, impressions, and cone-beam computed tomography (CBCT) analysis. PRF preparation utilized a minimally invasive venipuncture technique. Implant placement followed a two-stage surgical protocol, assessing primary stability with MEGA ISQ (Ostell). Post-surgery, patients received instructions and underwent recall for secondary stability after three months. Clinical parameters such as plaque index (PI), gingival index (GI), implant probing pocket depth (IPPD), sulcus bleeding index (SBI), and implant stability (IS) were systematically recorded. Robust statistical analyses, using IBM SPSS Statistics for Windows v20.0 (IBM Corp., Armonk, USA) software, incorporated Mann-Whitney U and Wilcoxon signed-rank tests for group and within-time point comparisons, with a significance level of p<0.05. This comprehensive study yields nuanced insights into the impact of PRF and implant procedures on key clinical parameters, contributing significantly to the field. RESULTS: This study compared dental implants with and without PRF in 24 patients. Both groups showed significant improvements in the PI, GI, and SBI. The PRF group exhibited higher IS in the third and sixth months, while IPPD was lower in the PRF group in the sixth month. CONCLUSION: The findings of the study highlight a positive impact on implant stability contributing to better implant outcomes.
ABSTRACT
Aim: The present study aimed to assess the clinical outcome of root coverage following coronally advanced flap with or without amniotic membrane in Miller's class I or class II localized gingival recession in relation to anteriors. Methods: Five patients with bilaterally symmetrical Miller's class I or class II localized gingival recession were included in the study. Each patient was divided into control (without amniotic membrane) and test sites (with amniotic membrane) arbitrarily. Clinical parameters including plaque index, probing pocket depth (PPD), clinical attachment level (CAL), and depth and width of the gingival recession were recorded in a pro forma at baseline and in the 2nd, 4th, 12th week. The results were tabulated and subjected to statistical analysis using analysis of variance (ANOVA). Results: A 0.600-mm, 0.400-mm, 2.630-mm, and 2.616-mm reduction in PPD and gain in CAL were observed at control and test sites in the 12th week postoperatively and was found to be statistically insignificant (P = 0.580 and P = 0.871, respectively). Changes in depth and width of the gingival recession were observed and found to be maximum between base line (2.28 mm, 3.01 mm, 2.71, and 3.09 mm) and 2nd week (0.00, 0.00 mm, 0.23, and 0.20 mm) but without statistical significance. Conclusion: From the above results of the study, it could be concluded that the use of amniotic membrane as a barrier along with coronally advanced flap did not influence the clinical outcome of root coverage procedure.
