Hi-Rem Polygon Post

Zirconia Glass Fiber Post

Hi-Rem Polygon Post are glass fiber posts with non-circular section.
As Overfibers post surfaces are particularly rough the silanization treatments are an optional.

Hi-Rem Polygon Post, the Overfibers’ patented fiber post, has the great advantage to be easily removable when it is necessary.

The central longitudinal axis of Hi-Rem Polygon Post is made of soft polymer macro-fiber, placing in this position doesn’t affect the resistance of the post, because the stresses are minimal (neutral axis).

Clinical Directions

Hi-Rem Polygon Post are the first Zirconia glass fiber posts with non-circular section present on the market. This characteristic, made possible by particular processing systems, which are part of the advanced Overfibers Know How.
They respects the morphology of the majority of the canals of single root teeth, adapting itself to the internal anatomy of the tooth canal (see photos A and B) with minimal removal of dental matter and maximum resistant section of the post.

A - Standard post section
B – Hi-Rem Polygon Post section

They are recommended for very stressed teeth, such as abutments of extended fixed prostheses or in partially removable combined prosthetic anchor teeth (removable prostheses).
Particularly recommended for single root premolars, canine teeth and incisors.
