Atlantis™ Abutment and Atlantis™ Crown Abutment are compatible with Ø5.4 Astra Tech Implant System EV.

Device Story

OsseoSpeed Angled Abutment EV and Atlantis Zirconia abutments serve as prosthetic interfaces for Astra Tech Implant System EV. Components connect endosseous implants to dental prostheses (bridges, overdentures, or crowns). Abutments are provided in various diameters, angles (20°, 30°), and gingival heights to accommodate anatomical variations. Used in dental clinics by clinicians to secure restorations via screw-retention, cementation, or friction fit. Device provides structural support for final dental restorations, restoring masticatory function and aesthetics for edentulous or partially edentulous patients.

Clinical Evidence

Bench testing only. Mechanical strength validated via dynamic fatigue testing per ISO 14801.

Technological Characteristics

Dental implant abutments; available in 3.6, 4.2, 4.8, and 5.4 mm diameters; 20° and 30° angulations; indexed and non-indexed interfaces. Materials consistent with predicate systems. Sterilized components. Mechanical fixation via abutment screws.

Indications for Use

Indicated for partially or fully edentulous patients requiring maxillary or mandibular dental implant-supported restorations, including bridges, overdentures, or single/multiple tooth prostheses.

Regulatory Classification

Identification

## INTENDED USE

OsseoSpeed™ Angled Abutment EV is intended to be used in conjunction with Astra Tech Implant System EV in fully edentulous or partially edentulous maxillary and/or mandibular arches to provide support for bridges or overdentures.

The AtlantisTM Abutment is intended for use with an endosseous implant to support a prosthetic device in a partially or completely edentulous patient. It is intended for use to support single and multiple tooth prostheses, in the mandible or maxilla. The prosthesis can be cemented, screw retained or friction fit to the abutment. The abutment screw is intended to secure the abutment to the endosseous implant.

The Atlantis™ Crown Abutment in Zirconia is intended for use with an endosseous implant to function as a substructure that also serves as the final restoration, in partially or completely edentulous patients. The prosthesis is screw retained. The abutment screw is intended to secure the crown abutment to the endosseous implant.

Atlantis™ Abutment and Atlantis™ Crown Abutment are compatible with Ø5.4 Astra Tech Implant System EV.

### DEVICE DESCRIPTION

OsseoSpeed Angled Abutment EV is designed for multi-unit, screw-retained restorations in a partially or fully edentulous situation. It is provided in three platform diameters (3,6, 4,2 and 4.8 mm) and two angles (20° and 30°). It is intended to fit Astra Tech implants of corresponding diameters cleared under K111287 and K120414. All abutments with a 20°angle are provided in two gingival heights (1.0 and 2.0 mm) with an indexed interface. All abutments with a 30°angle have a non-indexed interface and are provided in two gingival heights (1.0 and 3.0 mm).

OsseoSpeed Angled Abutment EV is not compatible with Astra Tech 3.0 mm diameter implants.

Atlantis Abutment in Zirconia for OsseoSpeed EV is a custom abutment for prosthesis attachment. Atlantis Crown Abutment in Zirconia for OsseoSpeed EV is fabricated as a custom single-tooth final restoration and is shaped in the design of the final prosthesis onto which porcelain is added. Both Atlantis abutments are provided in a platform diameter of 5,4 mm.

#### EQUIVALENCE TO MARKETED DEVICE

OsseoSpeed™ Angled Abutment EV is substantially equivalent in indications and design principles to the following legally marketed predicate devices:

Astra Tech AB - K111287 Astra Tech, Inc. - K112138 Astra Tech, Inc. - K110356

{2}------------------------------------------------

The purpose of this submission is to expand the OsseoSpeed Plus implant system to include three new components, the OsseoSpeed Angled Abutment EV, the Atlantis Abutment in Zirconia for OsseoSpeed EV, and Atlantis Crown Abutment in Zirconia for OsseoSpeed EV.

OsseoSpeed Angled Abutment EV is provided in two angles (20° and 30°). Platform sizes correspond to OsseoSpeed Plus implant diameters cleared in K111287. OsseoSpeed Angled Abutment EV is indicated for multi-unit restorations as are the predicate devices.

The original Atlantis Abutment in Zirconia for OsseoSpeed Plus was cleared in K112138 and the Atlantis Crown Abutment in Zirconia for OsseoSpeed in K110356. The interface remains the same as in K112138. A new size of Ø5.4 mm has been added for both designs.

Testing of OsseoSpeed™ Angled Abutment EV according to ISO 14801 Dentistry - Implants -Dynamic fatigue test for endosseous dental implants, was performed and the results show that OsseoSpeed™ Angled Abutment EV has sufficient mechanical strength for the intended clinical application and demonstrate that it is substantially equivalent to the listed predicate devices.

Overall, OsseoSpeed Angled Abutment EV has the following similarities to the predicate devices:

- has the same intended use,
- uses the same operating principle, . ●
- . incorporates the same basic design,
- . incorporates the same or very similar materials, and
- has similar packaging and is sterilized using the same materials and processes .
