Intended Use

The Atlantis 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 prosthesis, in the mandible or maxilla. The prosthesis can be cemented or screw retained to the abutment. The abutment screw is intended to secure the abutment to the endosseous implant. This device is compatible with the following manufacturers' implant systems: The Atlantis Abutment in Zirconia for Astra Tech Osseospeed Implant is compatible with the Astra Tech Osseospeed Plus 3.6mm and 4.2mm Implants. Please note: This device may be used in an early load situation, but is dependent on the specific implant system and protocol used by the dental professional. Highly angulated abutments on small implants are intended for the anterior region of the mouth only.

Device Story

Atlantis Abutment in Zirconia provides prosthetic support for dental implants; interfaces with Astra Tech Osseospeed Plus 3.6mm and 4.2mm implants. Device consists of yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) abutment and titanium alloy (Ti-6Al-4V ELI) screw. Used by dental professionals in clinical settings to support cemented or screw-retained restorations. Supports early load protocols depending on specific implant system. Benefits include restoration of dental function and aesthetics in edentulous patients.

Clinical Evidence

Bench testing only. Static and fatigue compression testing performed on worst-case implant assemblies to verify mechanical integrity and compatibility with Astra Tech Osseospeed Plus implants.

Technological Characteristics

Abutment material: Yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) per ISO 6972 & 13356. Abutment screw material: Titanium grade Ti-6Al-4V ELI per ASTM F-136. Mechanical interface: Abutment placed over implant shoulder, secured with titanium screw. No software or electronic components.

Indications for Use

Indicated for partially or completely edentulous patients requiring single or multiple tooth prosthetic support in the mandible or maxilla. Compatible with Astra Tech Osseospeed Plus 3.6mm and 4.2mm implants. Highly angulated abutments on small diameter implants restricted to anterior region.

Regulatory Classification

Identification

An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.

## INTENDED USE (continued)

Please note: This device may be used in an early load situation, but is dependent on the specific implant system and protocol used by the dental professional.

Highly angulated abutments on small implants are intended for the anterior region of the mouth only.

## DEVICE DESCRIPTION

The devices covered in this submission are abutments which are placed into the dental implant to provide support for a prosthetic restoration. The subject abutments are indicated for cemented or screw retained restorations. The Atlantis™ Abutment in Zirconia for Astra Tech Osseospeed Plus Implant for the Astra Tech Osseospeed Plus 3.6mm and 4.2mm Implants is made of biocompatible material, yttria-stabilized tetragonal for the zirconia polycrystals (Y-TZP) ( meets ISO Standards 6972 & 13356). Zirconia may have variation in shade. The abutment screw is made of Titanium grade Ti-6A1-4V ELI (meets ASTM Standard F-136). The zirconia abutments are placed over the implant shoulder and are mounted into the implant with a titanium screw.

## EQUIVALENCE TO MARKETED DEVICE

Astra Tech Inc. demonstrated that, for purposes of the FDA's regulations of medical devices, the Atlantis™ Abutment in Zirconia for Astra Tech Osseospeed Plus Implant is substantially equivalent in indication and design principles to the abutment in Astra Tech's Implant System K#111287 and the Atlantis™ Abutment in Zirconia for Astra Implants K#071946 which has been determined by FDA to be substantially equivalent to preamendment devices.
