Hahnenkratt fiber post refill 10pcs/kit
Exatec, Cytec and Contec
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.
HT means High Tenacity, for highest bending strength and fatigue resistance.
Also in 2001, the well-tried EXATEC system was completed by root posts made of carbon- and glass-fibre.
The advantages of the root post system Exatec, Cytec and Contec are:
High bending strength
of 1.857 MPa (EN ISO 178) of HT carbon fibre and
of 1.678 MPa (EN ISO 178) of HT glass fibre that optimizes the stability of the reconstruction.
Homogenity of the reconstruction
Glass- and carbonfibre posts 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.
