• Submission Type: Traditional
• Regulation: 21 CFR 872.3275
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Final cementation of ceramic, composite or metal inlays, onlays, crowns, bridges, 2-3-unit Maryland bridges and 3-unit inlay/onlay bridges (excluded for patients with bruxism or periodontitis); Final cementation of post and screws; Final cementation of ceramic, composite or metal restorations on implant abutments; Cementation of abutments made of Lava™ zirconium oxide ceramic.

Device Story

Unicem HM is a dual-curing (chemical and light), self-adhesive resin cement system supplied in a Clicker™ dispenser. It consists of a base paste and catalyst mixed in a 1:1 volume ratio. The material contains bi-functional (meth)acrylate and approximately 70% inorganic fillers (12.5 µm grain size). Used by dental professionals in clinical settings for the final cementation of various dental restorations, including ceramic, composite, or metal inlays, onlays, crowns, bridges, posts, screws, and implant abutments. The cement provides mechanical fixation and bonding to tooth structure and restorative materials. The dual-cure mechanism allows for both light-activated and self-curing polymerization, ensuring setting in both accessible and deep/opaque areas. The device benefits patients by providing a stable, radiopaque, and durable luting agent for restorative dentistry.

Clinical Evidence

Bench testing only. Performance evaluated against ISO 4049 and ISO 9917 standards. Metrics included film thickness (9±3 µm), working time (>60s), setting time (03:45), radiopacity (2.3 mm), flexural strength (57±11 MPa dark cured; 87±9 MPa light cured), compressive strength (247±16 MPa dark cured; 281±15 MPa light cured), and surface hardness. Biocompatibility testing was also performed.

Technological Characteristics

Dual-curing (chemical/light) resin cement; contains bi-functional (meth)acrylate; ~70% inorganic filler by weight (12.5 µm grain size); paste/paste delivery system (Clicker™ dispenser); radiopaque; conforms to ISO 4049 and ISO 9917 standards.

Indications for Use

Indicated for final cementation of ceramic, composite, or metal dental restorations (inlays, onlays, crowns, bridges, posts, screws, implant abutments) and Lava™ zirconium oxide ceramic abutments. Contraindicated for patients with bruxism or periodontitis regarding 2-3-unit Maryland bridges and 3-unit inlay/onlay bridges.

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.

#### Description for the Premarket Notification

i

Unicem HM 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 HM in the Clicker™ dispenser is a dual-curing, self-adhesive resin cement for hand mixing. It contains bi-functional (meth)acrylate. The proportion of inorganic fillers is about 70% by weight; the grain size (D 90%) is about 12.5 um. The mixing ratio; based on volume, is 1 part base paste : 1 part catalyst. The cement is available in various shades.

Unicem HM has been cleared under K062292. This 510(k) Premarket Notification has been submitted in order to seek clearance for additional new Indications for Use listed hereafter:

Final cementation of 2-3-unit Maryland bridges and 3-unit inlay/onlay bridges (excluded for patients with bruxism or periodontitis);

Final cementation of ceramic, composite or metal restorations on implant abutments Cementation of abutments made of Lava™ zirconium oxide ceramic.

The predicate devices to which Unicem HM has been compared are Unicem Aplicap/Maxicap by 3M ESPE AG, Germany (K094007, K020256), Panavia F 2.0 by Kuraray Medical Inc., Japan (K032455) and Maxcem 2 by Kerr Corporation, U.S.A., presumably marketed as Maxcem Elite (K073209).

As its predicate devices, Unicem HM is a dual-curing (chemical and light) resin based cement system containing methacrylate to be used with metal, composite, and porcelain restorations. Maxcem Elite and Unicem HM are both paste/paste systems.

The intended use of Unicem HM is comparable to the area of the intended use of the predicate devices of Unicem HM.

In this 510(k) premarket notification Unicem HM has been compared to its predicate devices with regard to chemical composition, performance data and indications for use. The comparison for chemistry, performance data and indications for use shows that Unicem HM is substantially equivalent to the predicate devices: Unicem Aplicap/Maxicap by 3M ESPE AG, Germany (K094007, K020256), Panavia F 2.0 by

Kuraray Medical Inc., Japan (K032455) and Maxcem 2 by Kerr Corporation, U.S.A., presumably marketed as Maxcem Elite (K073209).

The following table shows the performance data of Unicem HM and its predicate device Unicem Aplicap:
