Polygon Over Post

Glass Fiber Post

Polygon Over Post are the first “S” 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.As Overfibers post surfaces are particularly rough the silanization treatments are an optional.

Clinical Directions

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.
