Intended Use

The ERA® Micro 23° and 30° Females are intended to be used as a retention device in conjunction with the Sterngold Acid Etch Dental Implant System in the maxillary and/or mandibular arch to provide support for overdentures for partially and fully edentulous patients.

Device Story

ERA Micro 23° and 30° Female Abutments are prosthetic components for dental implants; facilitate functional parallelism of ERA females when implants diverge during prosthetic rehabilitation. Two-piece design: straight base with screw post for internal implant threading; angled female component. Used in maxillary/mandibular arches to support overdentures for partially/fully edentulous patients. Operated by dental professionals in clinical settings. Device provides mechanical retention for overdentures; allows clinicians to correct implant angulation issues, improving prosthetic fit and patient comfort.

Clinical Evidence

Bench testing only. Fatigue testing conducted per ISO 14801:2007 on worst-case scenario (30° angled female with 3.75mm diameter implant) at 40° angle of correction. Results demonstrated sufficient mechanical strength and fatigue resistance for intended clinical application.

Technological Characteristics

Two-piece screw-retained dental implant abutment. Material: 6AL-4V ELI titanium (ASTM F136-11). Female receptacle coated with titanium nitride (TiN). Available in 23° and 30° angles. Non-sterile, requires sterilization prior to use.

Indications for Use

Indicated for partially and fully edentulous patients requiring overdenture support in the maxillary or mandibular arch, used as a retention device with the Sterngold Acid Etch Dental Implant System.

Regulatory Classification

Identification

#### Product Description:

The ERA® Micro 23° and 30° Female Abutment is a prosthetic component intended to facilitate functional parallelism of the ERA® Females despite diverging implants during prosthetic rehabilitation. It is intended to be used in conjunction with the Sterngold Acid Etch Dental Implant System in the maxillary and/or mandibular arch to provide support for overdentures for partially and fully edentulous patients.

It is intended to support single and multiple tooth prostheses in the mandible or maxilla. It is provided in a 3.22mm diameter and two angles (23° and 30°).

These devices have a two piece design configuration; the two-piece assembly consists of a straight base which has a screw post that gets engaged into the internal threading of the dental implant and an angled female, which allows the user to achieve functional parallelism with divergent implants.

The specification for the material used to manufacture the ERA® Micro 23º and 30º Female is 6AL-4V ELI titanium classified as ASTM F136-11. The female receptacle of the ERA® Micro 23° and 30° female abutment, which resides at or above the gingival crest and couples with the Stern ERA System male attachments, is coated with titanium nitride (TiN), which has been cleared under K921010. No coating is applied to snap-in post of the angled female insert or the bases.

## Packaging:

These devices are supplied non-sterile in a sealed pouch including instructions for use. Instructions for Use indicate recommended method of sterilization prior to use. These parts are packaged individually.

#### Indications for Use:

The ERA® Micro 23° and 30° Females are intended to be used as a retention device in conjunction with the Sterngold Acid Etch Dental Implant System in the maxillary and/or mandibular arch to provide support for overdentures for partially and fully edentulous patients.

## Substantial Equivalence:

The proposed ERA® Micro 23° and 30° Females are substantially equivalent to other currently marketed devices that have been cleared by FDA through the 510(k) Premarket Notification process.

May 14, 2013 Micro 23° and 30° Female Abutments

Fatigue testing was conducted in accordance with ISO 14801:2007 Dentistry - Implants-Dynamic fatigue test for endosseous dental implants. The testing was conducted on a 30° angled female abutment and a small diameter (3.75mm) Sterngold Acid Etch Dental Implant finished product. This was determined to be the worst case scenario, largest angle, smallest diameter implant.

Samples were tested with the implants long axis at 40° angle of correction.

The hemispherical cap to fix the moment arm at 11mm, ensuring that no lateral constraint occurs is represented by a white ERA male component, which represents how this device is intended to be used.

Fatigue testing demonstrated that the ERA® Micro 23° and 30° Females have sufficient mechanical strength and resistance to fatigue for the intended clinical application and that they are substantially equivalent to the listed predicate devices.

#### Conclusion:

Based on our analysis, the proposed device is substantially equivalent in intended use, material, design and performance to its predicate devices.

- . has the same intended use
- . uses same or similar indications for use
- incorporates the same basic design 0
- incorporates the same or very similar materials
