Intended Use

Bonding adhesive restoration techniques. Direct filling technique: Adhesive bonding of composite materials to natural enamel and dentine (coltene® SYNERGY, coltène® Brilliant Dentin/Enamel/Incisal). Indirect restorative techniques: Adhesive bonding of ceramic and composite patterns with coltene® Duo Cement to natural enamel and dentine. Adhesive bonding of other dental materials: composite materials to pretreated ceramics; composite material to composite material; composite material to pretreated metals; dentine sealing. Sclerotic dentin: Use 35 % phosphoric acid for 30 s (e.g. coltene® Etchant Gel S).

Device Story

One Coat Bond is a light-cured, one-component dental adhesive system used by dentists for restorative procedures. It facilitates bonding of composite materials to enamel, dentine, ceramics, and metals. The system includes an etchant gel (Etchant 15) for surface preparation. The clinician applies the adhesive to the prepared tooth surface, followed by light-curing to polymerize the material. This creates a bond between the tooth structure and the restorative material, improving retention and sealing. The device is used in a clinical dental setting to restore tooth structure, potentially benefiting patients by providing durable, aesthetic, and functional dental restorations.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Light-cured, one-component adhesive. Composition: Hydroxyethyl methacrylate (HEMA), Hydroxypropylmethacrylate, Glycerinedimethacrylate, Polyalkenoate methacrylized, Urethanedimethacrylate, Amorphe silicic acid. Etchant: 15% phosphoric acid gel. Polymerization via light-curing.

Indications for Use

Indicated for adhesive bonding of dental restorative materials (composites, ceramics, metals) to natural enamel and dentine, and for dentine sealing. Contraindicated in patients with known allergies to components (HEMA, methacrylates, phosphoric acid), cases where the site cannot be isolated, or patients with poor oral hygiene.

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.
