Dental casting alloy used in combination with dental ceramics for fabrication of metallo-ceramic restoration.
Gold reduced palladium based casting alloy
The provided document is a 510(k) summary for a dental casting alloy, Hipallaur 19. It focuses on demonstrating substantial equivalence to a predicate device (Aurolite 2A) through a comparison of composition and physical/mechanical properties. This type of submission is not a clinical study report and therefore does not contain the information requested in your prompt regarding acceptance criteria, study design, expert ground truth, or human-AI performance.
The document discusses the technical characteristics of the device and its predicate, including:
-
Comparison of composition (weight %):
- Legal (Aurolite 2A): Au (13.5), Ag (27.8), Pd (49.5), Sn (4.6), In (4.4), Fe (0), Mn (0), Ru (x < 1%)
- New (Hipallaur 19): Au (19), Ag (10.4), Pd (57.1), Sn (10.3), In (2.3), Fe (0.3), Mn (0.5), Ru (0.1)
-
Comparison of physical and mechanical properties:
| ALLOY | Property | Aurolite 2A | Hipallaur 19 |
|---|---|---|---|
| Melting point (solid.) | 1270°C | 1210°C | |
| Melting point (liquid) | 1335°C | 1250°C | |
| Hardness (Vickers 5/30) | 170 (soft) | 270 (hard) | |
| 370 (hard) | |||
| Yield strength (MPa) | 462 (soft) | 640 (hard) | |
| 670 | |||
| Elongation (%) | 8 (soft) | 20 (hard) | |
| Density (g/cm³) | 14.6 | 13.7 |
- Test Methods Applied: ANSI/ADA 5 and ISO 9693 standards were used for testing the characteristics.
The report concludes that the new alloy (Hipallaur 19) is very similar to Aurolite 2A based on its constitution, with potentially slightly better corrosion resistance due to higher noble metal content.
In summary, the document does not contain the information you requested about acceptance criteria and a study proving device performance in a clinical or AI context because it is a regulatory submission for a dental casting alloy, not a clinical trial or AI performance study.

Discussion
Both alloys have the same constituents with the exception of two minor ones, i.e. Mn and Fe in Hipallaur 19. Nevertheless, these are oxidized out of the alloy during melting.
- Nevelliedess, aloos are onlines on ent (67.1 % vs. 63 %) and less silver and base metals.
Conclusion
AND A STATE A CALL A CARA A CARA
On the basis of the constitution the new alloy is very similar to Aurolite 2A, and it may be assumed that due to the higher noble metal content Hipallaur may have slightly better corrosion resistance.
