The Relationship Between Fibre Post Geometry and Flexural Properties: An Assessment Through a Modified Three-Point Bending Test
Abstract
Abstract - The aim of this study was to investigate the flexural properties of five types of fiber-reinforced dowels using a modified three-point bending test. Fiber-reinforced resin dowels were tested by a modified three-point bending test associated with models for cylindrical and conical simple-supported beams. The fracture load ranged from 86 to 246 N and the flexural strength from 423 to 1192 MPa. FRC Postec had significantly higher flexural strength and fracture loads values. Thus, the present study demonstrated higher flexural strength values for the FRC Postec fibre posts, suggesting that this system would present a better response to the forces of mastication.
KEY WORDS: Post. Fibre post. Flexural strength. Three-point bending test.
