The double taper closely matches the natural shape of the root canal. Scientifically tested and proven in practice since 2001. For further information please see our brochure »Exatec+Cytec+Contec«
Optimized Flexural Strength
HT-Glasfiber, translucent: 1.430 MPa (nach EN ISO 178)
HT-Glasfiber, 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
With CONTECeco, the particularly careful application of the adhesive system is essential, as CYTEC eco does not have the mesh-like retentions.
Today, it is undisputed that glass fiber root posts offer advantages for achieving long-lasting, stable root build-ups, such as a dentin-like modulus of elasticity that minimizes the risk of root fractures. In addition, in case revision of the root canal is necessary, it is much easier to perform when compared to titanium posts.
However, back in 1995, when the company E. HAHNENKRATT GmbH became the first in Germany to offer carbon fiber root posts, all established manufacturers were still focusing on titanium posts. After the introduction of Composipost in 1995, universities showed great interest, but it took many decades for conventional beliefs to change. In 1998, during the preparation of a dissertation at the Charité Medical Faculty of Humboldt University in Berlin, it was concluded that using a fiber-reinforced post in combination with dual-curing composites was considered much more complex than inserting a titanium post with zinc phosphate cement.*) Today, using composites and glass fiber root posts has become standard practice.

In this section, you will find answers to frequently asked questions about our dental instruments, as well as information on the materials, manufacturing, properties, and applications of our products.
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.
