Clinical Applications
1. Permanent Cementation of All‑Ceramic Restorations
3M RelyX U200 Resin Cement provides superior adhesive performance for permanent seating of all‑ceramic crowns and veneers. With excellent esthetic compatibility in Transparent, A2, or A3 shades, clinicians can achieve long‑lasting results that blend seamlessly with the patient’s natural dentition.
2. Metal and Composite Restorations
This advanced self‑adhesive dental cement is optimized for luting metal crowns, composite restorations, and porcelain‑fused‑to‐metal prostheses. Its formulation ensures strong and stable adhesion without the requirement of a separate bonding layer.
3. Bridges and Maryland Bridges
RelyX U200 delivers reliable fixation for multi‑unit bridges, including traditional 2‑3 unit fixed partial dentures and Maryland style bridges. Clinicians benefit from predictable retention and simplified cementation techniques.
4. Implant Abutment Restorations
Use this restorative resin cement for cementing ceramic, composite, or metal restorations onto implant abutments. The self‑adhesive chemistry supports durable adhesive bonding around implants where conventional bonding agents may fail.
5. Fiber Post Cementation
For post‑and‑core restorations, the strong adhesion and dual cure chemistry enable reliable fiber post bonding. This enhances post retention and supports long‑term restorative integrity.

How It Works : Innovative Resin Cement Technology
3M RelyX U200 Self Adhesive Resin Cement uses advanced adhesive monomers and fillers that interact with the tooth surface to form a chemical bond to enamel and dentin. The dual cure mechanism ensures polymerization in regions beyond the reach of curing lights, making it ideal for deep preparations and opaque restorations.
Unlike traditional cements that require step‑by‑step adhesive systems, this self‑adhesive luting cement streamlines procedures. Clinicians can simply prepare the restoration and tooth, dispense the RelyX U200 resin cement using an Automix Syringe or Clicker dispenser, seat the restoration, and allow the cement to cure through both chemical activation and light exposure.
Precise Delivery Formats Tailored to Clinical Needs
Automix Syringe
The Automix Syringe version offers:
- Balanced mixing for uniform consistency.
- Reduced air entrapment.
- Controlled extrusion for minimal waste.

Shade Selection Guide
Proper shade selection is crucial for esthetic restorations:
- Transparent : Best for highly translucent all‑ceramic restorations.
- A2 : Ideal for lighter tooth shades and natural dentition matching.
- A3 : Works beautifully for slightly darker tooth shades or enhanced esthetics.
Choosing the right shade ensures optimal cosmetic outcomes along with superior adhesion.
Step‑by‑Step Cementation Workflow
- Preparation: Clean and isolate the prepared tooth.
- Dispense: Use Automix or Clicker to apply cement to the internal surface of the restoration.
- Seat Restoration: Place the restoration with firm pressure.
- Remove Excess: Clean marginal excess before setting.
- Cure: Allow chemical cure with supplemental light cure as needed.
This simplified workflow increases efficiency and reduces procedural complexity.
Handling & Storage Guidelines
- Store at recommended temperatures.
- Avoid contamination with moisture.
- Use within the expiration date for optimal performance.
- Recap syringes and cartridges after use.
Proper handling preserves the material properties and maintains consistent bonding results.
Ideal For Dental Professionals In:
✔ General dentistry
