Intended Use

TempoCem Clear is indicated for: - Temporary or semipermanent luting of temporary and permanent crowns, bridges, inlays and onlays. - Temporary luting of temporary veneers - Temporary or semipermanent luting of implant-borne dental prosthesis.

Device Story

TempoCem Clear is a transparent, dual-curing, resin-based dental cement; used for temporary or semipermanent luting of dental restorations (crowns, bridges, inlays, onlays, veneers) and implant-borne prostheses. Device consists of two pastes (base and catalyst) in a double-barreled syringe; automatically mixed via single-use mixing tips upon dispensing. Operated by dental professionals in a clinical setting. Provides mechanical fixation of provisional or permanent restorations to teeth or implant abutments. Benefits include ease of use, esthetic transparency, and fluoride release. Clinical decision-making is supported by the cement's physical/mechanical properties, ensuring stable retention of restorations during the temporary or semipermanent phase.

Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing of physical and mechanical properties (solubility, water sorption, dimensional change, gel/setting time, film thickness, peak polymerization temperature, compressive/flexural/shear bond strength, and fluoride release) and biocompatibility testing per ISO 7405.

Technological Characteristics

Dual-curing resin-based dental cement; glass filler in multifunctional methacrylate matrix. Free of methyl methacrylate and peroxides. Filler content: 40 wt% (22 vol%). Packaged in double-barreled syringe with automix tips. Biocompatibility per ISO 7405. Technical properties: 19.0 µg/mm³ water solubility, 65.5 µg/mm³ water sorption, 78 MPa compressive strength, 8.7 MPa shear bond strength.

Indications for Use

Indicated for temporary or semipermanent luting of temporary/permanent crowns, bridges, inlays, onlays, temporary veneers, and implant-borne dental prostheses.

{5}------------------------------------------------

TempoCem Clear is similar to the predicate device Telio CS Link in that they are both automixing, transparent, dual-curing temporary resin dental cements to be used for cementing restorations such as crowns, bridges, inlays and onlays. The devices have substantially equivalent physical and mechanical properties.

TempoCem Clear is different from the predicate device in that it contains sodium fluoride. The subject and predicate devices have slightly different Indications for Use language. The Indications for Use for Telio CS Link do not mention, but do not exclude, the use for specific restorations (temporary and permanent crowns, bridges, inlays, onlays, and veneers). The Intended Use for Telio CS Link as presented in the K042846 Summary was: "For the temporary cementation of temporary inlays, onlays, partial crowns, crowns or bridges." The differences in the Indications for Use affect neither the Intended Use nor substantial equivalence.

The reference predicate device, Telio CS Cem Implant, has the same FDA Product Code (EMA= Dental cement) as TempoCem Clear. Telio CS Cem Implant is a selfcuring resin cement with lightcuring option for the esthetic, temporary, reversible / semi-permanent cementation of restorations on implant abutments. The Indications for Use for Telio CS Cem Implant ("Reversible/semi-permanent cementation of longterm temporary and permanent restorations on implant abutments") are similar to the specific Indication for Use for TempoCem Clear ("Temporary or semipermanent luting of implant-borne dental prosthesis."). The composition of Telio CS Cem Implant (bismethacrylates (approx. 52 %wt.) and fillers (approx. 46 %wt.). Initiators, stabilizers, auxiliaries and piqments are additional components.) is substantially equivalent to TempoCem Clear. Thus TempoCem Clear is similar to the reference predicate Telio CS Cem Implant in composition, curing and indications.

## 7. Non-Clinical Performance Data

Physical and mechanical properties of TempoCem Clear were investigated and compared to the predicate device in accordance with FDA's 1998 Guidance for Industry and FDA Staff: Dental Cements - Premarket Notification (chemistry of the

{6}------------------------------------------------

setting reaction, working and setting times, solubility, dimensional change, bonding strength, film thickness, heat generated during setting and biocompatibility), Comparative data relevant for temporary, dual-curing cements demonstrate substantial equivalence of TempoCem Clear to the predicate device, Telio CS Link.

The biocompatibility testing was performed according to the FDA 1998 Guidance and the following consensus standard:

- ISO Standard 7405 Second edition (2008): Dentistry Evaluation of biocompatibility of medical devices used in dentistry
Equivalence in biocompatibility to the predicate device was demonstrated in cytotoxicity studies.

In addition, TempoCem Clear can be compared to other currently marketed dental products also manufactured by DMG: Luxatemp Ultra (K101710), Luxatemp / Luxatemp-Solar (K013674) and Luxatemp Automix (K924830). These dual-cure or auto-cure devices are not temporary cements, but have many similarities in curing mechanism and composition with TempoCem Clear. For example, the same auto-cure system and many of the same resin and pigment components are used in TempoCem Clear. The Luxatemp products have been marketed world-wide for over 25 years, and there is considerable clinical experience with these products and their components. This experience provides further evidence for the biocompatibility of the materials in TempoCem Clear.

### 8. Clinical Performance Data

Not applicable. Clinical performance testing has not been performed for the proposed device.

### 9. Conclusions

.

Based on the device Indications for Use, composition and physical / mechanical properties, TempoCem Clear has been shown to be substantially equivalent to the predicate device.
