To registration / loginExatec–Ti: Passive titanium root posts with a micro-rough surface.
Optimization of the stability of the root reconstruction
The conical apical part has the advantage that it can be designed longer than a cylindrical shape and has an exceptionally small end. This allows the conical Exatec post to be inserted deep into the root canal.
A root post with a tapered apical part offers many advantages over a cylindrical post:
Due to the tapered shape, which corresponds to the natural contour of the tooth root, more tooth substance is preserved in the critical area of the root tip, thus minimizing the risk of root fractures.
At the transition from post to head, which is prone to breakage, the tapered Exatec post has rounded transitions and a larger post cross-section compared to a cylindrical post of the same apical length. The Exatec post thus has higher stability and achieves higher values in bending load tests.
The Exatec calibration drill prepares a precisely fitting axial support for the Exatec post head, which inherently determines the position where the post has dentin contact without exerting pressure on the root wall, as the downward movement of the post is precisely stopped at the axial support.
The precise support ensures the axial support of the post head in the dentine and stops precisely the movement of post to the apical direction.
The Exatec Calibration Drill with integrated head cutter calibrates a precise support.

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.
