Dental Fiber post - Atra POST
Composite posts are used in dentistry to strengthen the structure of teeth that have undergone endodontics treatment.
After denervation and evacuation and preparation of the root canal the composite posts are inserted into the canal with adhesive cements and form the basis for placing the dental veneer or making the tooth with a
Restorative composite.
Atrak Polymer Tech Co. has marketed its composite fiberglass posts under the brand name of Atra Post.
Atra Post is composed of an epoxy polymer matrix as well as reinforcing glass-fibers. In these post, the glass fibers are stretched longitudinally through the pultrusion process.
Atra Post also includes a stainless steel filament to provide better visibility in the radiographic images.

- It is recommended to keep at least 3 to 5mm of root filling in the apical part to have a proper seal.
- Cut the Atra Post with a dental drill under running water. Do not use scissors or pliers for cutting.
