In 1995 E. HAHNENKRATT GmbH was the first company offering a root post made of carbon fibre and in 1997 the first one offering glass fibre posts in Germany, followed in 1998 by a root post made of quartz fibre. In 2001 at the IDS in Cologne the new post system CYTEC was presented, which is produced with posts made of HT-carbon or HT glass fibres.

The advantages of the root post system Contec are:

High bending strength
of 1.678 MPa (EN ISO 178) of HT glass fibre that optimizes the stability of the reconstruction.

Homogenity of the reconstruction
Glass- have an elastic attitude that is more similar to the dentine as i.e. Titanium or Zirconium. Consequently the root post, the composite and the remnant tooth can create a biomechanical homogeneous unit, supporting the stability of the reconstruction.

Functional post design
The post consists of a cylindrical and a conical apical part. The rounded retentions in the head-section support secure bonding and additionally serve to anti-rotation. In the apial section the spiral escape grooves ensure decompression and retention.

Micro retentive surface
As a result of the micro retentive surface that is structured by fibres no silanisation is necessary.
