Objective:
To develop a new type of fiber reinforced composites (FRC) posts with optimal bent angles.
Methods:
Three kinds of experimental bent posts were made with bent angle of 5 degrees, 10 degrees, and 15 degrees respectively. The flexural strength of all FRC posts was tested with a 3-point bending test.
Results:
The flexural strength of the posts with 15 degrees was significantly lower than that of 5 degrees and 10 degrees post groups and prefabricated straight group (P < 0.05). There was no significant difference in flexural strength within other groups (P > 0.05).
Conclusions:
The experimental FRC posts with bent angles of 0 degrees, 5 degrees, 10 degrees can be accepted clinically.
