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 titanium abutments are compatible with the Keystone 3.5mm, 4.1mm and 5.0mm Keystone Implants. The zirconia abutments are compatible with the Keystone 3.5mm, 4.1mm and 5.0mm Keystone 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 angled abutments on small diameter implants are intended for the anterior region only. ## Device Story Atlantis Abutment is a dental prosthetic component placed into an endosseous implant to support cemented or screw-retained restorations. Used in dental clinics by dental professionals; device provides structural interface between implant and prosthesis. Titanium or zirconia abutment is secured to the implant using a titanium screw. Device supports single or multiple tooth replacements in mandible or maxilla. Clinical benefit includes restoration of dental function and aesthetics for edentulous patients. Early loading is possible depending on specific implant system protocols. ## Clinical Evidence Bench testing only. Static and fatigue compression testing performed on worst-case implant assemblies using Atlantis angled titanium and zirconia abutments with Keystone implants. Results demonstrated compatibility and that the system supports appropriate loads, performing as intended. ## Technological Characteristics Materials: Titanium alloy (Ti-6Al-4V ELI, ASTM F-136) and yttria-stabilized tetragonal zirconia polycrystals (Y-TZP, ISO 6972 & 13356). Form factor: Abutment for 3.5mm, 4.1mm, and 5.0mm implant diameters. Mechanical fixation via titanium screw. No software or electronic components. ## Regulatory 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. ## Special Controls *Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control.

The subject abutments are indicated for cemented or screw retained restorations. The Atlantis™ Abutment for Keystone Implant and abutment screw are made of Titanium grade Ti-6A1-4V ELI (meets ASTM Standard F-136) for the 3.5mm, 4.0mm, 4.1mm and 5.0mm sizes. In addition, the Atlantis™ Abutment for Keystone Implant for the 3.5mm, 4.1mm and 5.0mm sizes are also made of biocompatible material, yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) and meets ISO Standards 6972 & 13356). Zirconia may have variation in shade. The titanium and 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 for Keystone Implant is substantially equivalent in indications and design principles to Lifecore's predicate devices: PrimaConnex Internal Connection Implant System cleared under K051614 and PrimConnex Ceramic Abutments cleared under K062876, each of which has been determined by FDA to be substantially equivalent to preamendment devices. {2}------------------------------------------------ Premarket Notification Section 5: Page – 6 | Table 1: Substantial Equivalence Summary | | | |------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Technological<br>Characteristics | Atlantis™ Abutment for<br>Keystone Implant | Keystone Primaconnex<br>Implant System | | Material | -Titanium Alloy<br>-Biocompatible ceramic<br>material | -Titanium Alloy<br>-Biocompatible ceramic<br>material | | Performance characteristics | Allows the prosthesis to be<br>cemented or screw retained to<br>abutment.
