HAHNENKRATT GmbH was the first company in Germany to offer a carbon fiber 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 system, which is manufactured with root posts made of HT carbon fiber or HT glassfiber.
HT stands for High Tenacity, for highest bending strength and fatigue resistance.
Also in 2001, the Exatec system, which has proven its worth since 1986, will be supplemented with root posts made of both material.

The advantages of the Exatec, Cytec and Contec root post systems are:

The high bending strength
of 1,678 MPa (EN ISO 178) for HT glassfiber optimizes the stability of the root construction.

Homogeneity of the root construction
The fiber composite materials have an elastic behavior that is more similar to that of dentin than that of titanium or zirconium, for example. The root post, composite and residual tooth thus form a more homogeneous unit that supports the stability of the construction.

Functional post design

The shape of the post consists of a cylindrical and a conical apical part. In the head area, rounded retentions support bonding with the composite and they also serve as anti-rotation. In the apical region, spiral-shaped grooves provide decompression and retention.

Microretentive surface
The fiber-structured, microretentive surface eliminates the need for silanizing.
