Intended Use

EnaCem is a dual curing radiopaque fluorescent luting composite, available in several dentine colours, for cementation of posts, ceramic and composite inlay, onlay veneers and crowns. It can be used also for core build-up and as a liner.

Device Story

ENA CEM is a dual-curing, radiopaque, fluorescent luting composite used by dentists for permanent cementation of dental prostheses (posts, ceramic/composite inlays, onlays, veneers, crowns). The high-viscosity version (ENA CEM HF) also functions as a core build-up material and liner. The device is supplied in self-mixing syringes. It is applied by the clinician to the dental appliance or tooth structure during restorative procedures. The material polymerizes via a dual-cure mechanism (light and chemical) to provide structural bonding and restoration support. Benefits include improved wear resistance and versatility in restorative dentistry.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on material composition, physical characteristics, and intended use compared to existing dental composite cements. Cytotoxicity testing was performed and results are referenced in the appendix.

Technological Characteristics

Dual-curing radiopaque fluorescent composite. Composition: resin matrix (polymerizable monomers) and glass fillers. Form factor: self-mixing syringes. Conforms to ISO 4049:2000 for polymer-based filling, restorative, and luting materials.

Indications for Use

Indicated for cementation of posts, ceramic and composite inlays, onlays, veneers, and crowns; also indicated for core build-up and as a liner. For use by dental professionals.

Regulatory Classification

Identification

Zinc oxide-eugenol is a device composed of zinc oxide-eugenol intended to serve as a temporary tooth filling or as a base cement to affix a temporary tooth filling, to affix dental devices such as crowns or bridges, or to be applied to a tooth to protect the tooth pulp. Dental cement other than zinc oxide-eugenol is a device composed of various materials other than zinc oxide-eugenol intended to serve as a temporary tooth filling or as a base cement to affix a temporary tooth filling, to affix dental devices such as crowns or bridges, or to be applied to a tooth to protect the tooth pulp.

### 510(k) Summary

Submitter: Mr. Eugenio Miceli, QA Manager, Micerium SpA. Via Marconi, 83, 16030 Avegno (GE), Italy. Phone: [phone].

- I. Classification Name and Number: Cement, dental (EMA 872.3275).
- II. Common/Usual Name: Dental cement for post and core, direct and indirect restoration.
- Proprietary Name: ENA CEM. III.
- IV. Registration No .: K062355
- V. "ISO 4049:2000 Dentistry - Polymer - Based Filling, Restorative and Luting materials".
- VI. Description of the Device: The ENA CEM is a luting material available in a flowable consistency (Ena Cem) and also in a high viscous version (Ena Cem HF) that is available in different colours. Both can be used for cementing prosthesis appliances made in laboratory to the tooth. They can be used also for post-cementation. Ena Cem HF can also be used for core build-up and as a liner. The accessories and try-in materials contact tissue for less than 1 hour and therefore are exempt from 510(k) requirements and are described only generally.
- VII. Labels and Labeling: Draft labels of the ENA CEM and instructions for use are provided.
- VIII. Substantial Equivalence: The ENA CEM system is substantially equivalent to some other dual composite cements currently on the market used by dentist for luting prosthesis made with several types of dental materials as well as for post and core. A list of these is provided.

The composition of these dental composite cements is very similar: resin matrix made of polymerizable monomers, (glass) fillers, and all of them are dual cure materials, The packaging is similar because all products are packaged in self mixing syringes. Regarding indications, all products can be used for luting of almost all dental appliances. Physical characteristics are similar although one version of Ena Cem, Ena Cem HF, has better physical properties that allow also the core build up and a better performance regarding wear resistance.
