Ultradent’s UniCore^® Post and Drill System provides all the items needed for strong, esthetic, radiopaque restorations — including color-coded posts and the only three-in-one color-coded drill on the market. UniCore posts match the characteristics of dentin, minimizing the likelihood of root fracture. The use of fiber posts results in a more natural-looking restoration than those done with metal posts. Prestressed fibers run the length of the posts for superior strength. Posts are perfectly matched to a durable drill that can be used for up to 15 procedures to remove rigid, carrier-based obturators, gutta percha, or composite from canals as part of a post-placement procedure. The drill may also be used for up to five procedures to remove existing fiber posts.

UniCore Post
Each UniCore post’s microporous surface ensures a mechanical, microretentive bond with cement, with no chairside chemical treatment required. Radiopaque beyond the highest ISO standards, UniCore’s translucent posts allow light curing of dual-cure cement to the core material. Each post is gently tapered to work in harmony with natural tooth anatomy and can be easily removed if endodontic retreatment is required.

UniCore Drill
The ultrasafe UniCore drill features a patented, diamond-coated collar to prevent binding in access openings. Each drill and post is color matched according to size — simplifying chairside use. The UniCore drill’s uniquely designed flutes ensure rapid and consistent removal of obturators from the canal, and the heat-generating tip facilitates rapid removal of stubborn obturators, gutta percha, and fiber posts.

IMPORTANT NOTE: Sterilize drills and posts before use.

Step 1: Position the Unicore tip in the pilot hole. Using light pressure, follow the obturation material to the length indicated by the rubber stop. Keeping the drill at full speed, withdraw from the canal. Rinse debris, and blow out excess water with TriAway^™ Adapter.

Step 2: Verify post size by placing the corresponding UniCore post and seat to length. Trim post to appropriate length using a diamond disc.

Step 3: Etch space for 20 seconds with Ultra-Etch^®, using the Endo-Eze^® 22ga tip. Suction excess etchant with Luer Vacuum Adapter and Endo-Eze 22ga tip. Use TriAway Adapter to rinse throroughly with water, then lightly air dry, leaving the post space slightly damp.

Step 4: Use the NaviTip^® FX tip to place Peak^® Universal Bond in the canal for 10 seconds. Dry using TriAway Adapter, then light cure the space for 20 seconds. Using the UniCore post or paper point, ensure post space is not obstructed with Peak Universal Bond.

Step 5: Attach the Intraoral tip to PermaFlo^® DC syringe, mix, then deliver PermaFlo DC into the post space, beginning from the bottom. Insert post and seat.

Step 6: Light cure PermaFlo DC in the canal for 20 seconds. Deliver PermaFlo DC around the post for core buildup. If the fill starts to slump, light cure for 2 to 3 seconds. Repeat for each additional layer, followed by a final cure of 20 to 40 seconds (40 seconds if using a curing light with less than 600mW/cm²). Proceed with crown preparation or restorative procedure.
