Comprehensive Indication Coverage and Workflow Simplification

RelyX™ Universal Resin Cement is formulated as a dual-cure resin cement suitable for both adhesive and self-adhesive modes of use. This versatility supports indirect procedures including crowns, bridges, inlays/onlays, posts, and veneers composed of materials such as zirconia, lithium disilicate, and PFM. Using a single cement for multiple indications allows practice-wide protocol standardization and may simplify material management. Dr. Akit Patel has noted that, “we no longer need to stock multiple resin cements or learn different steps for different materials,” underscoring the utility for inventory consolidation.

Scotchbond™ Universal Plus Adhesive is a single-bottle, light-cure adhesive compatible with total-etch, selective-etch, and self-etch techniques. Its application encompasses direct composite, core build-ups, and the adhesive mode for indirect restorations, making it suitable for use as the universal adhesive in both restorative and prosthodontic procedures.

Bond Strength and Adhesive Performance

Strong and durable adhesion to both tooth substrate and restorative material is central to restoration longevity. Scotchbond™ Universal Plus contains MDP monomer and silane, supporting chemical bonding to a range of substrates — including dentin, enamel, zirconia, glass-ceramics, and metal. Independent laboratory testing and manufacturer data consistently report high bond strength values to both enamel and dentin, with average microtensile bond strength to dentin in the range of 35–40 MPa under standard ISO conditions.

The radiopacity of Scotchbond™ Universal Plus enhances radiographic identification, reducing misinterpretation of restoration margins and recurrent caries. The adhesive’s consistency facilitates uniform application. Dr. Claire Burgess highlights the absence of postoperative sensitivity in her clinical use, a finding corroborated by several publications reporting minimal sensitivity rates in composite placement when following manufacturer protocols.

For indirect restorations or preparations with reduced retention, the combination of RelyX™ Universal Resin Cement (in adhesive mode) with Scotchbond™ Universal Plus provides high bond strength without the need for a separate primer. This closed system supports predictable outcomes with lithium disilicate, zirconia, and high-strength ceramic restorations.

Handling Properties and Cement Cleanup

Clinical feedback and in vitro studies consistently note improved handling properties with RelyX™ Universal. The material provides adequate working time and a tack-cure phase designed for controlled excess removal. Dr. Chris O’Connor observes that, “cleanup is easier and more predictable compared to previous cements,” which can reduce chairside time and improve efficiency, especially in deep margin or subgingival situations.
