ORION GX ALLOY is a yellow. high noble, gold-based dental alloy.
This document describes regulatory correspondence for the ORION GX ALLOY and does not contain information about acceptance criteria or a study proving device performance against such criteria. The document states that the device is "substantially equivalent" to legally marketed predicate devices based on its formulation and historical use in Europe, along with biocompatibility test results. However, it does not provide specific acceptance criteria or details of a study designed to demonstrate performance against those criteria in a structured manner as requested in the prompt.
Therefore, I cannot provide the requested information in the table format or answer the specific questions about sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment based on the provided text.
The closest relevant information is:
- Predicate Devices: Degudent H Alloy K821446
- Technological Characteristics: "All of the components found in ORION GX ALLOY have been used in legally marketed devices. ORION GX ALLOY is very similar in formulation to legally marketed dental alloys. This alloy has been on the European market since 1978 with over 1.5 million units placed."
- Biocompatibility Testing: "ORION GX ALLOY was tested for Cytotoxicity and AMES mutagenicity and found to be non-cytotoxic and non-mutagenic."
These points serve as the basis for the FDA's substantial equivalence determination, but they are not presented as acceptance criteria with corresponding performance data from a specific study as outlined in the prompt's request.
§ 872.3060 Noble metal alloy.
(a)
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.(b)
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.
