Clinical efficacy of titanium prepared platelet rich fibrin in periodontal regeneration: A systematic review and meta-analysis.

BACKGROUND

Periodontal regeneration therapies frequently involve autologous platelet concentrates (APCs). They can be used in sinus lift surgeries and socket preservation, among other clinical settings. Platelet rich fibrin (PRF) membrane has been used to treat gingival recession in individuals or groups of individuals using a coronally progressed or lateral pedicle flap. In the treatment of mixed periodontic endodontic lesion/furcation defect, PRF functions as a healing and interpositional biomaterial, filling a cystic cavity. PRF is known to help the bone regeneration process. In the last few years, efforts have been made to enhance the PRFs characteristics and quality. One of them is titanium platelet rich fibrin (T-PRF). Third-generation platelet concentrate no longer contains silica, and its preparation in glass vacuum containers, that no longer creates any known concerns. The effectiveness PRF's has been evaluated in connective tissue and bone repair. The aim of this study is to compare T-PRF to other platelet concentrates and different treatment modalities for periodontal regenerative procedures.

METHODS

A protocol of this systematic review have been registered in prospero (CRD42022293545). The online database searched were PUBMED, COCHRANE for published articles up to November 2022 without language restrictions. Studies in trial registers, handsearching, bibliographic references of relevant articles were also checked. Data collection and analysis was done by individual authors. Independent eligibility assessments were conducted by four review authors. Then, using the standard Cochrane methodology, four review authors extracted the data and evaluated the risk of bias for individual studies. We developed "Summary of findings" tables and used GRADE to evaluate the evidence.

RESULTS

Three studies were included for meta-analysis. Results of meta-analysis supported that T-PRF is effective for correction of both hard and soft tissue defects.

CONCLUSIONS

The overall qualitative and quantitative analysis suggest that T-PRF has superior structural properties and thicker fibrin network for ensuring predictable success periodontal regenerative procedures.
