Intended Use

Bonding between dentin/enamel and silorane based composite filling materials Bonding between dentin/enamel and methacrylate based composite filling materials

Device Story

Hermes Bond is a resin tooth bonding agent applied to the interior of prepared dental cavities to improve restorative material retention. It is used by dentists in a clinical setting. The device eliminates the need for a separate etching step, reducing application errors and post-operative sensitivity. Based on methacrylate chemistry, it provides efficient etching of dental hard tissue and initiates polymerization of silorane-based composites at the interface. A blend of co-monomers facilitates the formation of a uniform adhesive film on dentin and enamel while enabling chemical crosslinking between OH-functionalized methacrylates and siloranes. The output is an adhesive layer that secures the composite filling, benefiting the patient by improving restoration longevity and reducing chair time.

Clinical Evidence

Bench testing only. Performance data demonstrates bond strength comparable to the predicate device (Adper Prompt L-Pop) when used with conventional methacrylate composites.

Technological Characteristics

Resin tooth bonding agent based on methacrylate chemistry. Contains acidic methacrylates for etching and co-monomers for adhesive film formation and chemical crosslinking with siloranes. Designed for application to dentin and enamel. Class II device (21 CFR 872.3200).

Indications for Use

Indicated for bonding dentin and enamel to either silorane-based or methacrylate-based composite filling materials in dental patients.

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 for the Premarket Notification

Hermes Bond is classified as Resin Tooth Bonding Agent (21 C.F.R. § 872.3200) because it is a device intended to be painted on the interior of a prepared cavity of a tooth to improve retention of a restorative material.

Like Adper Prompt L-Pop, 3M ESPF's well-known and well-established resin bonding agent, Hermes Bond offers the advantages of a simplified bonding procedure, eliminating

{1}------------------------------------------------

the need for a separate etching step. Thus it reduces both possible crrors during application and post-operative sensitivity. Additionally, it saves the dentist valuable chair time.

Being based on methacrylate chemistry itsclf, Hermes Bond is well suited for bonding methacrylate composites. The compatibility to silorane based composites is ensured by the formulation of Hermes Bond which has especially been optimized for this purpose. The acidic methacrylates provide efficient etching of the dental hard tissue and initiation of the polymerization of the siloranc-based composite (e.g. "Hermes")at the interface with the adhesive. The blend of co-monomers allows at the same time formation of a uniform adhesive film on dentin and enamel, and additional chemical crosslinking between OHfunctionalized methacrylates and siloranes.

In fact, the bond strength obtained for Hermes/Hermes Bond is comparable to that of Adper Prompt L-Pop with conventional methacrylate composites.

The comparison for chemistry, performance data and indications for use shows that Hermes Bond is substantially equivalent to the predicate devices.

In summary, it can be concluded that safety and effectiveness requirements for Hermes Bond are completely met.
