Intended Use

Adhesive fixing of ceramic, composite or metal inlays, onlays, crowns, bridges, posts, screws, veneers and orthodontic strips.

Device Story

Unicem is a dental adhesive cement used to affix dental devices such as crowns, bridges, inlays, onlays, posts, screws, veneers, and orthodontic strips. The device is used by dental professionals in a clinical setting. This modification introduces 'Unicem HM,' a multi-dose handmix version dispensed via the 3M ESPE 'Clicker' delivery system, supplementing existing single-dose 'Aplicap' and 'Maxicap' systems. The cement consists of a base and catalyst paste. The device provides fluoride ion release. Clinical benefit is derived from the secure adhesive fixation of dental restorations, improving prosthetic retention and stability.

Clinical Evidence

Bench testing only. Physical and chemical properties of the modified Unicem HM were compared to the predicate Unicem. Fluoride release rates were measured in accordance with the FDA guidance document 'Dental Cements - Premarket Notification' (August 18, 1998).

Technological Characteristics

Dental cement (Product Code: EMA). Multi-dose handmix delivery system (Clicker) or single-dose capsules (Aplicap/Maxicap). Composed of base and catalyst pastes. Features fluoride ion release capability. Class II device.

Indications for Use

Indicated for the adhesive cementation of dental restorations including ceramic, composite, or metal inlays, onlays, crowns, bridges, posts, screws, veneers, and orthodontic strips in patients requiring dental prosthetic fixation.

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.

#### Predicate Device

Unicem by 3M ESPE, K 002364

## Description for the Premarket Notification

Unicem is classified as a Dental cement other than zinc oxide-eugenol (21 C.F.R. §872.3275[b]) because it is a device composed of various materials other than zinc oxideeugenol. Unicem is intended to affix dental :.cvices such as crowns and bridges. Unicem currently is available in two single dose delivery systems called Unicem Aplicap™ and Unicem Maxicap™. The existing and 510(k) cleared device Unicem is modified as follows: A multi-dose handmix version of Unicem, called Unicem HM, will be added to the single dose delivery systems. Unicem HM is considered as a modification to its predicate device Unicem. Unicem HM consists of a base and catalyst base and will be available in 3M ESPE's multi-dose device Clicker™. The intended use of Unicem HM is the same as cleared for Unicem, and the slight differences in chemical composition have been assessed for any effects regarding biocompatibility. The physical and chemical properties of Unicem HM were compared to those of Unicem. Furthermore, the physical-chemical property to release fluoride ions is added to the product description of Unicem. For this purpose, the fluoride release rates of Unicem have been measured following the guidance document: "Dental Cements - Premarket Notification" issued by CDRH on August 18, 1998, section 6.0. In summary, Unicem modified as described in this 510(k) premarket notification submission is, in our opinion, substantially equivalent to the predicate device.
