Dental casting alloy for making dental restorations and appliances.
Device Story
Aurecast 4 is a low gold, silver-palladium based dental casting alloy. It is used by dental professionals to fabricate Type IV dental restorations and appliances. The device is provided as a metal alloy for casting processes. It functions as a restorative material, replacing missing tooth structure or providing structural support for dental prosthetics. The clinical benefit is the restoration of dental function and aesthetics for patients requiring dental prostheses.
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. No clinical data was required or provided.
Technological Characteristics
Low gold, silver-palladium based casting alloy. Composition: Au (4%), Ag (45.7%), Pd (30.3%), Cu (17.6%), Zn (2.3%), Ru (0.1%). Physical properties: Melting range 940-1020°C; Vickers hardness 195 (soft) to 265 (hard); Yield strength 460 MPa (soft) to 700 MPa (hard); Elongation 10% (soft) to 3% (hard); Density 10.6 g/cm3. Tested per ANSI/ADA 5 and ISO 8891.
Indications for Use
Indicated for use in dental casting 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. See § 872.1(e) for availability of guidance information.
