Fiber-reinforced composites (FRC) can potentially help in a physiologic stress transmission
due to its excellent biomechanical matching with living tissues. Novel one-piece
FRC implants and abutments with two different fiber orientations were loaded until failure
to assess the load-bearing capacity, fracture patterns, and precision of fit. The onepiece
FRC implants showed significantly higher load-bearing capacity compared to FRC
abutments regardless of the fiber orientation (p<0.001). For FRC abutments, bidirectional
abutments showed significantly higher loads compared to unidirectional abutments
(p<0.001). The type of structure and fiber orientation are strong determinant factors of
the load-bearing capacity of FRC implants and abutments.
