Material and methods: Through this biomechanical analysis a carbon fiber post (CF), a glass fiber post (GF) and a titanium post (TI) were compared according to their design (tapered [T]) and serrated [S]) and under a load of 250 N, at 45º, in order to simulate an occlusal load of a canine tooth. Results: FEA demonstrated the following maximum displacement (MXD) in millimeters: T.CF (tapered carbon fiber post) = 2.48 mm; T.GF = 1.58 mm; T.TI = 0.50 mm; S.CF = 7.66 mm; S.GF = 4.87mm. Conclusion: These results showed that the carbon fiber post demonstrated the greatest displacement, followed by the glass fiber and the titanium posts. The tapered design presented detachment values much lower than the serrated design. 2011 artículo científico 1806-7727 https://www.redalyc.org/articulo.oa?id=153018891011 en http://www.redalyc.org/revista.oa?id=1530 RSBO Revista Sul-Brasileira de Odontologia application/pdf Universidade da Região de Joinville RSBO Revista Sul-Brasileira de Odontologia (Brasil) Num.2 Vol.8 |
