Reconstruction of dental restorations.

Device Story

e-Sarang 86, DM-78, and DM-55 are gold-based dental casting alloys used by dental professionals for the fabrication of dental restorations, including inlays, onlays, crowns, fixed partial dentures, and removable partials. The alloys are cast into specific shapes to restore tooth structure or replace missing teeth. The device is used in a dental laboratory or clinical setting. The output is a physical dental prosthetic that provides structural support and functional replacement for damaged or missing teeth, benefiting the patient by restoring oral function and aesthetics.

Clinical Evidence

No clinical data. Safety and effectiveness were established through bench testing and literature review of dental gold alloy biocompatibility.

Technological Characteristics

Gold-based dental casting alloys. Materials and design are similar to predicate gold-based alloys. No specific ASTM standards or software components are described.

Indications for Use

Indicated for reconstruction of dental restorations. e-Sarang 86 is indicated for inlays in non-stress-bearing areas. DM-78 is indicated for full crowns, 3/4 crowns, and short-span fixed partial dentures. DM-55 is indicated for full crowns, long-span fixed partial dentures, and removable partial dentures. Contraindicated in patients with allergies to metals.

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.

Dear Mr. Mouser:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
