It is intended for manufacturing - Crowns - Short span bridges - Long span bridges - Removable partials and can be used for • Telescopic and milling work Porta Implant can be veneered with suitable dental ceramics as well as with dentalcomposites.

## Device Story

Porta Implant is a gold-palladium-platinum ceramic alloy (97.6% noble metal content) used by dental technicians to fabricate dental restorations, including crowns, bridges, and removable partials. The alloy is designed for porcelain fusing, offering high sag resistance, making it suitable for implant supraconstructions. It is veneered with dental ceramics or composites. The device is used in dental laboratories; it provides a biocompatible, corrosion-resistant material for restorative dentistry, enabling the creation of durable, functional dental appliances for patients.

## Clinical Evidence

No clinical data. Bench testing only; device complies with ISO 9693 and European directive 93/42/ECC.

## Technological Characteristics

Gold-palladium-platinum ceramic alloy; 97.6% noble metal content. High sag resistance at porcelain fusing temperatures. Corrosion resistant. Complies with ISO 9693.

## Regulatory 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.

#### Device description

PORTA IMPLANT is a gold-palladium-platinum ceramic alloy with high contents of noble metals (97,6%) intended for dental technicians to fabricate dental restorations.

It has an indication for use which ranges from single crowns up to long span bridges with two or more pontics. At porcelain fusing temperatures, it has a high sagresistance and therefore it is suitable for manufacturing of implant supraconstructions.

PORTA IMPLANT is highly corrosion resistant and has an excellent biocompatibility. It fully complies to the international standard ISO 9693 and fulfills the essential requirements of the European directive 93/42/ECC concerning medical devices.

PORTA IMPLANT can be veneered with suitable dental ceramics and with dental composites.

Dear Dr. Polzer:

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.
