Intended Use
Dental casting alloy for making restoration.
Device Story
Aurecast 74 is a high gold casting alloy used by dental professionals for the fabrication of Type III dental restorations. The device is a metallic material supplied for clinical use. It functions as a restorative material, replacing lost tooth structure. The alloy is processed by dental technicians or dentists through casting techniques to form the final restoration. The clinical benefit is the provision of durable, biocompatible dental restorations for patients requiring tooth repair.
Clinical Evidence
Bench testing only. Physical and mechanical properties (melting point, Vickers hardness, yield strength, elongation, density) and chemical composition were compared to the predicate device. Testing conducted per ANSI/ADA 5 and ISO 1562 standards.
Technological Characteristics
High gold casting alloy. Composition: Au 74.1%, Ag 13.4%, Pd 2.3%, Pt 1.6%, Cu 6.8%, Zn 1%, Sn 0.7%, Ir 0.1%. Physical properties: Melting range 930-970°C, Vickers hardness 130-210, yield strength 310-390 MPa, density 16.3 g/cm3. Tested per ANSI/ADA 5 and ISO 1562.
Indications for Use
Indicated for use as a dental casting alloy for the fabrication of dental restorations.
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. See § 872.1(e) for availability of guidance information.

## Discussion
The noble metal content is equivalent. There is a negligable difference in the other constituents, Aurecast 74 contains Sn for improved brazing properties.
## Conclusion
In practical respect are the two alloys identical.
