ABSTRACT
Objetivo: realizar uma revisão da literatura acerca do uso do PRF na Implantodontia nos últimos anos, abordando artigos científicos recentes. Material e métodos: foi realizada uma busca na base de dados PubMed, ente os meses de setembro e outubro de 2016, utilizando a associação das palavras-chave na língua inglesa "PRF" e "dental implants". Posteriormente, foi feita uma complementação nas bases de dados Scielo e Google Acadêmico com os mesmos termos na língua portuguesa. Resultados: dez artigos foram selecionados, uma vez que os mesmos respeitavam os critérios de inclusão, incluindo metodologia detalhada, número significativo de pacientes e realização de procedimentos relacionados à instalação de implantes dentais. Todos os estudos avaliados reportaram alguma vantagem no uso do PRF, principalmente em relação ao ganho ósseo. No entanto, todos os estudos apresentaram limitações e apontaram a necessidade de estudos subsequentes com adequada padronização. Conclusão: após a revisão destes estudos, foi possível concluir que o PRF pode ser indicado como adjuvante nos procedimentos de enxertia e na instalação de implantes, e também pode ser utilizado como barreira mecânica em procedimentos em que esta manobra seja necessária para o sucesso final do procedimento de enxertia.
Objective: the aim of the study was to review the literature concerning the use of the PRF in Implantology in the past few years, taking into account the recent articles published in relation to this subject. Material and methods: a search was made on the PubMed (Medline) database, between September and October of 2016, with the terms "PRF" and "dental implants" and also a complementary search in Scielo and Google Academic databases, with the correspondent terms in Portuguese. Results: ten articles were included in the study, once they fulfill the inclusion criteria revealing a detailed methodology, a significant number of patients and with procedures related to the installation of dental implants. All studies evaluated reported some advantage concerning the use of the PRF, mostly in relation to the gain in the bone level. However, all studies also declared limitations of their methodologies and pointed to the necessity in the development of further studies with standard protocols. Conclusion: after revision of the mentioned articles, it was possible to conclude that the PRF can be used as an adjuvant in the grafting procedures and in the dental implant installation, also, can be used as a mechanical barrier in procedures that this kind of barrier is necessary to ensure success in the grafting procedure.

Aims: To evaluate the effi cacy of autologous platelet- rich fi brin in regeneration of bone and to assess clinical compatibility of the material in mandibular third molar extraction socket. Materials and Methods: This study was conducted in 20 patients visiting the out patient department of Oral & Maxillofacial Surgery, Subbaiah Institute of Dental Sciences. Patients requiring extraction of bilateral symmetrical mandibular third molars were taken for the study. Following extraction, platelet rich fi brin prepared from patients own blood was placed in one extraction socket. The patients were assessed for postoperatively pain, periodontal pocket depth and bone blending and trabecular formation. Radiological assessment of the extraction site was done for a period of 6 months to evaluate the change in bone density. Results: All the local signs and symptoms of infl ammation were mild to moderate and subsided in normal course of time. Pain was less in study site compared to control site. Soft tissue healing was better in study site. Evaluation for bone blending and trabecular bone formation showed earlier in study (prf)site compared to control(non prf) site in 10 patients. The evaluation of bone density by radiological assessment showed the grey level values calculated at 4months at the prf site were comparatively higher than the average baseline value of bone density at extraction site in control site. Conclusion: The study showed that autologous PRF is biocompatible and has signifi cant improved soft tissue healing,bone regeneration and increase in bone density in extraction sockets. However a more elaborate study with a larger number of clinical cases is very much essential to be more conclusive regarding its effi cacy.
