Intended Use

Dental casting alloy for making dental restorations and appliances.

Device Story

Aurecast 10 is a low-gold, silver-palladium based dental casting alloy. It is used by dental professionals for the creation of Type IV dental restorations and appliances. The device functions as a restorative material, providing the necessary physical and mechanical properties for dental applications. It is supplied as a metal alloy for casting processes in a dental laboratory setting.

Clinical Evidence

Bench testing only. Physical and mechanical properties (melting point, hardness, yield strength, elongation, density) were compared against the predicate device using ANSI/ADA 5 and ISO 8891 test methods.

Technological Characteristics

Low-gold, silver-palladium based casting alloy. Composition: 10% Au, 59.9% Ag, 20% Pd, 9% Cu, 1.0% Zn, 0.1% Ru. Physical properties: Melting point 1000-1030°C; Density 10.6 g/cm3. Tested per ANSI/ADA 5 and ISO 8891 standards.

Indications for Use

Indicated for use as a dental casting alloy for the fabrication of dental restorations and appliances.

Regulatory Classification

Identification

A noble metal alloy is a device composed primarily of noble metals, such as gold, palladium, platinum, or silver, that is intended for use in the fabrication of cast or porcelain-fused-to-metal crown and bridge restorations.

Special Controls

*Classification.* Class II (special controls). The special control for these devices is FDA's “Class II Special Controls Guidance Document: Dental Noble Metal Alloys.” The devices are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 872.9.

## Discussion

The major components of the two alloys are identical and their concentration is the same. The only difference is in the small amount of Zn and the grain refiners such as Ru and Ir. These minor differences have negligible effect upon the alloys.

## Conclusion

The two alloys are practically identical
