3M™ RelyX™ fiber post 3D refill size 1, 56949. Features: - Featuring coronal 3D macro retention, the 3M™ RelyX™ Fiber post 3D glass fiber post system offers high mechanical retention to the core build-up material. - Its microporous surface also provides a strong bond in the root canal without a silanating step, while its enhanced radiopacity enables better post position control. - Features a microporous surface, enabling a strong bond to the root canal without a silanating step. - Coronal 3D macro retention creates high mechanical retention to the core build-up material. - Offers excellent radiopacity for better post position control. - Simplifies procedures with no primer or pre-treatment required. - Dentin-like elasticity results in a low risk of root fracture. - More esthetic option than a metal post. - Flattened side helps improve handling. Suggested applications: - Supporting and securing coronal restorations in cases with insufficient residual tooth structure. Package contents: - 10 Posts – Size 1 (1.3 mm dia.) Yellow.
