CONTEC is suitable for roots with a more conical shape. The double taper closely follows the natural shape of the root canal.
HAHNENKRATT was the first company in Germany to offer a carbon fiber root post as early as 1995. In 1998, the first quartz fiber post followed. At IDS 2001, we introduced the new build-up system CYTEC, featuring root posts made of HT-Carbon Fiber or HT-Glass Fiber.
As the demand for carbon fiber root posts has significantly decreased in recent years for aesthetic reasons, we now offer CYTEC & CONTEC exclusively as glass fiber posts.
The white, semi-translucent root posts made of HT-Glass Fiber provide the ideal foundation for aesthetically pleasing restorations.

- Optimized Flexural Strength
HT-Glass Fiber, translucent: 1.430 MPa (nach EN ISO 178)
HT-Glass Fiber, opaque: 1.400 MPa (nach EN ISO 178) - Optimized Fatigue and Fracture Resistance
- Homogeneity through Dentin-like Modulus of Elasticity
- Optimized, strong bond to composite
- High radiopacity
The surface of our root canal posts is retentive. Under SEM, the micro-retentive structure of the glassfiber can be seen, enabling a strong adhesive bond with the composite—without the use of a silane—simple and efficient.
Results from a scientific study at the University of Rostock confirm this for the CYTEC system.
The results are transferable to CONTEC, as both posts share the same surface structure.
This scientific study was conducted in collaboration between the »Clinic for Dental Prosthetics« and the »Institute of Biomedical Engineering« at the University of Rostock.
The study investigated »The influence of macro- and microstructure on the wetting and retention properties of root canal posts in vitro«.
CYTEC achieved the highest bond strength in comparison. This demonstrates that the unique surface structure of the root posts supports micro-retentive adhesion and leads to optimized bonding between the post and the adhesive cement.
