Intended Use

A material primarily intended to be used as a bonding-promoting substance between tooth substance and dental restorations. It may also be used as a dentin sealant and as a bonding agent for repair of restorations.

Device Story

ADH19 is a one-component dental adhesive used by dentists in clinical settings to bond restorative materials to tooth structure. It functions via self-etch, selective enamel etch, or total-etch modes. Unlike its predicate, it requires no separate dual-cure activator for self- or dual-cure materials. The clinician applies the adhesive to the tooth surface or restoration substrate; it acts as a bonding agent for direct and indirect procedures, including fillings, veneers, and core build-ups. By facilitating adhesion between tooth substance and restorative materials (metals, ceramics, composites), it improves restoration retention and seals dentin, potentially reducing sensitivity and preventing microleakage.

Clinical Evidence

Bench testing only. In vitro studies compared shear bond strength of ADH19 to Scotchbond Universal across multiple substrates (enamel, dentin, titanium, zirconia, NPM alloy, composite, high gold alloy, feldspathic glass ceramic, lithium disilicate) using various curing modes. Results confirmed ADH19 performance is comparable to the predicate.

Technological Characteristics

One-component dental adhesive containing monomers, fillers, solvents, initiators, silanization agents, and stabilizers. Delivery via vial or L-Pop unit dose. Supports self-etch, selective enamel etch, and total-etch modes. Complies with ISO 29022:2013 for notched-edge shear bond strength testing. Biocompatibility assessed per ISO 10993 series and ISO 7405.

Indications for Use

Indicated for bonding methacrylate-based light-, dual-, and self-cure composite or compomer filling materials; root surface desensitization; bonding methacrylate-based fissure sealants; protective varnish for glass ionomer fillings; repair of composite and compomer fillings; sealing cavities prior to amalgam restoration; cementation of indirect restorations; bonding methacrylate-based core build-up materials and cements; cementation of veneers; intraoral repair of composite, porcelain fused to metal, and all-ceramic restorations; and sealing cavities/tooth stumps prior to temporary cementation.

Regulatory Classification

Identification

A resin tooth bonding agent is a device material, such as methylmethacrylate, intended to be painted on the interior of a prepared cavity of a tooth to improve retention of a restoration, such as a filling.

## Description of Device

ADH19 is a one-component dental adhesive that is based on the chemistry of Scotchbond Universal (by 3M Deutschland GmbH, K110302, cleared as ADHESIVE EXL-759). It can be used in a self-etch mode, selective enamel etch mode or in a total-etch mode for both direct and indirect dental restorative procedures. It is intended to bond methacrylate-based restorative, cement and sealant materials to dentin, enamel, glass ionomer and various indirect restorative substrates (metals, glass ceramics, alumina and zirconia). The primary use will be with lightcured materials, however it will have the capability to also bond self- or dual-cure composite and cement materials. In contrast to Scotchbond Universal, no separate Dual Cure Activator will be necessary in this case.

Table Comparison to Predicate Technology

ADH19 and Scotchbond Universal are dental adhesive materials containing monomers, fillers, solvents, initiators, silanization agents and stabilizers. 3M Deutschland GmbH is providing

{6}------------------------------------------------

information to the Agency regarding information to FDA about the composition of ADH19 and compared this to the predicate device.

In vitro testing was conducted to show the performance of ADH19 compared to the predicate device Scotchbond Universal regarding shear bond strength to enamel (self-etch & total-etch), to dentin (self-etch & total-etch), to restoration materials titanium, zirconia, NPM alloy, composite, high gold alloy, feldspathic glass ceramic, lithium disilicate, with RelyX Ultimate to enamel and dentin, and with different self cure and dual cure composites to enamel and dentin. The results of ADH19 are comparable to Scotchbond Universal. In summary, 3M Deutschland GmbH concludes that ADH19 is substantially equivalent to the predicate devices regarding performance and physical and mechanical properties.

#### Biocompatibility

The biocompatibility assessment for the products was conducted in accordance with the following guidance:

Table Guidances for biocompatibility assessment

The biocompatibility of ADH19 has been assessed by a board-certified toxicologist according to recommendations in FDA guidance and internationally recognized standards for medical and dental devices. The conclusion of the assessment is ADH19 is safe for its intended use.

## Conclusion

Comparisons of the indications for use/intended use, composition, technology, and physical and mechanical properties showed that ADH19 does not raise any new questions about safety and effectiveness and is substantially equivalent to the predicate device.
