CONTEC is suitable for roots that are rather conical. The double cone approximates the natural shape of the root canal.
HAHNENKRATT was the first company in Germany to offer a carbonfiber root post back in 1995. This was followed in 1998 by the first root post made of quartzfiber. At IDS 2001, we introduced the new CYTEC root post system, made with HT-Carbon Fiber and HT-Glass Fiber root posts.
As the demand for carbon fiber root posts has decreased considerably in recent years for aesthetic reasons, we no longer offer the CYTEC & CONTEC as carbon fiber posts but only as glass fiber posts.
The white, semi-translucent root posts made of HT-Glass Fiber provide you with the basis for esthetically successful restorations.
Explore the details
- Optimized flexural strength
HT-Glassfiber, translucent: 1.430 MPa (according to EN ISO 178)
HT-Glassfiber, opaque: 1.400 MPa (according to EN ISO 178) - Optimized fatigue and fracture resistance
- Dentin-like elastic modulus for a homogeneous restoration
- Optimized, strong adhesive bond to composite materials
- 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.
