Over Post+

Over Post+

Zirconia Glass Fiber Post

The innovative fiber post with AAS (Active Adhesion System), the biomimetic matrix-integrated bonding principle of Over Post+, to increase the adhesion with OverCEM SA Self-Adhesive luting cement through a tested chemical interaction.

Over Post+ are glass fiber posts with conical-cylindrical shape. As Overfibers post surfaces are particularly rough the silanization treatments are an optional.

Clinical Directions

Over Post+ are specific for teeth with missing or massively destroyed crowns as they present the maximum emergency diameter at the level where they come out of the root, according to the most recent studies regarding the root canal shapes of the teeth treated endodontically.

Their special quality is having a large emergency coronal diameter compared to the relatively small apical diameter: this design stabilizes the prosthetic core much more effectively, making the restoration more resistant to the displacing forces of mastication.
