Hi-Rem Polygon Post

Clinical Directions

For canals with non-circular section.
These represent a brand new creation, as they are the first “S” glass fiber posts with elliptic section present on the market. 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. 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.
Hi-Rem Polygon Posts and Polygon Drills are available in three sizes, with color coding for a corresponding use.

Hi-Rem Post, the Overfibers’ patented fiber post, it is the only one that 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)

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

Fig.A-B : In non-circular and oval canals, compared to the common circular section (A), the Hi-Rem Polygon Post offers a resistant section which is almost double (B). Note how the diameter Ø is the same in the two posts. A: Standard posts with circular section overlapped at the root canal entrance of a lower premolar; B: Hi-Rem Polygon Post with non-circular section overlapping the same tooth: the resistant section (light blue area) is almost double that of the previous one, and is capable of bringing a much higher level of resistance to the restoration.

THE SHAPE
For all clinical requirements
According to the most recent studies about root canal anatomy, Overfibers carried out the analysis of root canal shapes and identified many possible endodontic spaces available before post restoration, allowing the statistical characterization of the different post shapes now available from Overfibers

Hi-Rem Prosthetic Post
For teeth with missing or massively destroyed crowns
Hi-Rem Endodontic Post
For teeth which have a moderate residual coronal structure
