UniCore™

Post and Drill System

UniCore posts are composed of glass fibers. The translucent and radiopaque UniCore Post responds to compressive forces as dentin would, without compromising the durability of the restoration. The gentle taper of the UniCore Post corresponds to the natural anatomy of the tooth and perfectly matches the post space created by the UniCore Drill. ​The UniCore post is noticeably more radiopaque than the leading competitor. The benefit of this glass-fiber post is that it allows light to be transmitted all the way down to the bottom of the post space.1 UniCore glass fiber posts have a flexural strength similar to dentin.2 When used with PermaFlo DC resin, UniCore Posts showed better bond strengths than competitors.3

The five sizes and colors of UniCore Posts correspond to those of the UniCore Drill. The UniCore Drill is unique in its ability to remove obturators while preparing a post chamber that perfectly corresponds to its post. The UniCore drill features a patented heat-generating tip, which facilitates the removal of fiber posts, rigid carriers, and traditional gutta percha. The drill’s heat-dissipating, diamond-coated collar preserves tooth structure, and its specially designed flutes cut canal walls laterally instead of vertically.

Technical Details

Durable UniCore Drill Is Safe and Easy to Use

​The drill’s heat-dissipating, diamond-coated collar preserves tooth structure, and its specially designed flutes cut canal walls laterally instead of vertically.

UniCore Drill Can Perform Post Preparations and Remove Obturators

​The UniCore drill features a patented heat-generating tip, which facilitates the removal of fiber posts, rigid carriers, and traditional gutta percha. The durable drill can be used to remove gutta percha or rigid carriers for as many as 15 post preparations or post removal during retreatments, and/or up to five preexisting fiber post removals when a retreatment is necessary.

Color-Coded System

​The UniCore drills and posts are color coded according to size, simplifying chairside use.

Posts Are Composed of Enhanced Zirconium Glass Fibers

UniCore glass fiber posts have a flexural strength similar to dentin.2

Frequently Asked Questions

  • How are glass-fiber posts superior to standard posts?

    ​The UniCore post is noticeably more radiopaque than the leading competitor. The benefit of this glass-fiber post is that it allows light to be transmitted all the way down to the bottom of the post space.1

  • Why is it beneficial to have a heat-dissipating, diamond-coated collar drill?

    ​A heat-dissipating, diamond-coated collar drill preserves tooth structure. The heat-generating tip eases all obturator removal procedures, and our patented diamond-coated drill collar prevents binding in access openings The UniCore drill is also specially designed with flutes that cut canal walls laterally instead of vertically.

  • Are any drill sizes ok to use for removing fiber post preparations?

    ​UniCore size 0 drill is not appropriate for the removal of existing fiber post preparations.

  • How many times can you reuse the drills for procedures?

    ​The durable drill can be used to remove gutta percha or rigid carriers for as many as 15 post preparations or post removal during retreatments, and/or up to five preexisting fiber post removals when a retreatment is necessary.
