Intended Use

Multilink Automix is used for the permanent cementation of indirect restorations where a strong bond is desired: - Inlays, onlays, crowns, bridges and root posts made of: – - Metal and metal ceramics - All-ceramics, in particular opaque zirconium oxide ceramics - Composites and fibre-reinforced composites

Device Story

Multilink Automix is a self-curing and self-etching luting composite system for permanent cementation of indirect dental restorations. Used in dental clinics by professionals; applied with Multilink Primer; Monobond Plus recommended as coupling agent for bonding to alloys, zirconium, aluminum oxide, and silicate ceramics. Device provides mechanical fixation and chemical bonding to tooth structure and restorative materials. Benefits include strong, durable retention of indirect restorations. Performance is verified through physical property testing (flexural strength, bond strength, radiopacity) to ensure clinical suitability.

Clinical Evidence

Bench testing only. Evaluated per ISO 4049:2000 for water absorption, water solubility, radiopacity, flexural strength, modulus of elasticity, compressive strength, and shear bond strength. Biocompatibility evaluated per ISO 10993. Results demonstrate performance comparable to the predicate device.

Technological Characteristics

Self-curing/self-etching luting composite system. Materials tested per ISO 4049:2000. Properties include radiopacity (350% Al), flexural strength (70-110 MPa), and compressive strength (240-280 MPa). Delivery via automix system. Biocompatibility per ISO 10993.

Indications for Use

Indicated for permanent cementation of indirect restorations including inlays, onlays, crowns, bridges, and root posts composed of metal, metal-ceramics, all-ceramics (specifically opaque zirconium oxide), composites, and fiber-reinforced composites.

Regulatory Classification

Predicate Devices: Multilink (K032470)

Multilink Automix is a self-curing and self-etching luting Device Description: composite system for the adhesive luting of indirect restorations made of metalceramic all-ceramic and composite. Multilink Automix is applied together with the selfetching and self-Ocuring Multilink Primer. Monobond Plus is recommended as a coupling agent to achieve a strong bond to precious and non-precious alloys, as well as to all ceramics made of zirconium and aluminum oxide and silicate ceramics.

The predicate device to which Multilink Automix has been compared is Multilink (K032470). For this application. Multilink Automix has been compared to its predicate with regard to chemical composition, performance data and indications for use. The comparison shows that Multilink Automix is substantially equivalent to the predicate device.

## Intended Use:

Multilink Automix is used for the permanent cementation of indirect restorations where a strong bond is desired:

- Inlays, onlays, crowns, bridges and root posts made of: –
- o Metal and metal ceramics
- o All-ceramics, in particular opaque zirconium oxide ceramics
- o Composites and fibre-reinforced composites

Technological Characteristics: The device design, i.e. delivery form, and intended use of Multilink Automix and the predicate device are the same. The composition of the subject device has been modified from the predicate, however, there are no ingredients in the subject device which pose any new issues of safety and effectiveness.

Testing Summary: The device was tested in accordance with ISO 4049:2000 for Polymer based dental restorative materials for Water Absorption, Water solubility, radiopacity, Flexural Strength, Modulus of Elasticity, Compressive Strength and Shear Bond Strength and the results from testing demonstrates that Multilink Automix is substantially equivalent to the predicate device. Biocompatibility testing and evaluation was also carried out according to ISO 10993.
