To registration / loginCONTEC 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 quartz fiber. At IDS 2001, we introduced the new CYTEC root post system, made with HT-carbonfiber or HT-Glass Fiber root posts.
As the demand for carbonfiber root posts has decreased considerably in recent years for aesthetic reasons, we no longer offer the CYTEC & CONTEC as carbonfiber 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.
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.

Titanium root posts: High rigidity, but higher risk of root fractures
HT glass fiber root posts: Better force distribution, dentin-like modulus of elasticity to minimize root fractures
1. CYTEC
• Material: HT glass fiber (High Tenacity)
• Shape: Cylindrical-conical
• Surface: Micro-retentive, no silanization needed
• Application: For roots that are mostly cylindrical
• Available in various diameters (e.g., 1.0 mm to 2.1 mm)
2. CONTEC
• Material: HT glass fiber (High Tenacity)
• Shape: Double cone
• Surface: Micro-retentive
• Application: For roots with a conical shape
3. EXATEC
• Material: HT glass fiber or titanium (EXATEC-Ti & EXATEC-S)
• Shape: Conical in the apical area, some with a post head
• Surface: Micro-retentive (for glass fiber versions)
• Application: Especially suitable for teeth with severely destroyed coronal areas
The main difference between FS (Front Surface) and RS (Rear Surface) lies in the position of the reflective coating and the resulting image quality:
1. FS (Front Surface) mouth mirror
2. RS (Rear Surface) mouth mirror
The new pro modules feature the same outstanding qualities as the trusted CONTEC and CYTEC root posts, which have been proven for over 30 years, especially through:
pro LightTransmitting along the entire apical area of the post enables optimized and at the same time shortened initial curing of the composite, right up to the tip of the root post. In a tightly scheduled workflow, every second counts, providing valuable time savings so the dentist can proceed immediately to the next step without delay.
HAHNENKRATT mouth mirrors are manufactured with high-quality mirror coatings and precision components.
Front surface mirrors (FS) prevent double images and provide a clear, distortion-free view.
Depending on the model, different coating technologies are used to optimize brightness, contrast, and durability.
This results in reliable optical quality for precise work in everyday dental practice.
The abbreviations SS and CS refer to the thread types of mouth mirrors and their compatibility with handles:
SS (Simple Stem)
Used in Europe and other regions
CS (Cone Socket)
Conical thread (Cone Socket).
Especially common in the USA, Canada, South Korea, and Spain.
