of 1,857 MPa (EN ISO 178) for HT carbon fiber and
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
The shape of the postconsists of a double cone. 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
Exatec, Cytec and Contec differ from other root posts the special mesh structure of the post. This micro-retentive surface supports the adhesive bond between the post and the resin (bonder/composite). The result is a secure fastening – even without the use of a silane – quite simple and efficient.
