Clinical Overview
The UniCore™ system by Ultradent is a matched glass-fiber post and drill system designed for efficient post‑endodontic restoration. Translucent, radiopaque UniCore Posts mimic dentin’s flexural modulus and taper anatomically to conserve tooth structure while facilitating strong, esthetic bonding. The corresponding UniCore Drill features a heat-generating tip and lateral-cutting flutes engineered to remove gutta‑percha, plastic carriers, or fiber posts and prepare a perfectly matching post chamber.
Key Benefits
- Superior strength & flexibility: Glass-fiber posts flex like dentin under load, reducing risk of root fracture.
- True-to-fit design: Color-coded posts and drills (Sizes 1–4, 0.8‑1.5 mm) ensure perfect seating by matching drilled post space.
- Efficient retreatment capability: Heat‑generating drill tip removes obturators or old posts—up to 15 uses for gutta-percha and 5 uses for fiber-post removal.
- Tooth-safe preparation: Diamond‑coated, heat‑dissipating drill collar and lateral‑cutting flutes minimize thermal trauma and excess dentin removal.
- High esthetic and radiographic visibility: Translucent, radiopaque posts allow efficient light curing to full depth and easy X‑ray identification.
- Microporous bonding surface: Optimizes retention through resin cement adhesion without chemical surface treatment.
Kit Contents
- 4 × UniCore Drills (Sizes 1–4; 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm)
- 20 × UniCore Posts (5 of each size 1–4)
- Color-coded, spill-proof module housing all components
- Instruction for Use guide
Working & Functional Details
- Reusability: Each drill supports approximately 15 gutta‑percha removal procedures or up to 5 fiber-post removals in retreatment cases.
- Compatible with resin cements: Microporous post surfaces and translucent core allow immediate light curing and strong bonding with materials like PermaFlo™.
- Accessory posts available: For flared or irregular canals, accessory posts expand adaptability.
Indications
- Restoration of endodontically treated anterior or posterior teeth requiring post & core
- Removal of plastic/ fiber posts and gutta‑percha during retreatment
- Post space preparation with matching anatomical taper and minimal dentin removal
- Use in standard and flared canals (via accessory posts)
Instructions for Use
- Select drill size matching intended UniCore Post based on canal diameter.
- Use drill to remove obturation material or existing post; limit use per drill per guidelines.
- Prepare post space—drill creates precisely matching chamber for corresponding post.
- Clean and dry canal; optionally use accessory posts in flared canals for improved adaptation.
- Place UniCore Post with resin cement; light‑cure through translucent post to full depth.
- Finish core buildup and proceed with definitive restoration.
Summary
The Ultradent UniCore™ Post & Drill System Complete Kit (Ref. 7120) is a comprehensive, clinician-designed solution for predictable post-endodontic restorations. Featuring anatomically tapered, translucent glass-fiber posts matched to precision drills with heat-generating tips, it simplifies post-placement and retreatment workflows while preserving tooth structure and enhancing esthetics, strength, and long-term retention.
