### 4. Device Description:
The Zimmer Zfx Titanium Abutment for the NobelActive Implant system is designed for use with NobelActive and NobelReplace Conical Connection endosseous dental implants to support single or multi tooth restorations. The abutment/implant interface is an internal conical connection with a hexagonal interlock.
The Zimmer Zfx Titanium Abutment for NobelActive Implant System is a patient specific dental implant abutment with a competitor compatible interface. The purpose of a Patient-Specific abutment is to satisfy customer needs that are otherwise difficult to meet with off-the-shelf abutments. They can be manufactured in multiple sizes, shapes, and angles within the limits established in this submission. They frequently incorporate the modifications typically done at a dental laboratory or "chair-side" by a dentist. Traditional methodologies require the customer (dentist/laboratory technician) to begin with a "stock" abutment and use manual subtractive techniques to remove material from this original "stock" design. However, a Patient-Specific abutment will incorporate these same modifications desired by the customer (dentist/laboratory technician) at the time of fabrication at the manufacturing facility.
The engineering drawings list ranges in areas (attributes) of the abutment that may be modified depending upon patient-specific needs.
The abutment is composed of Titanium alloy (Ti6Al4V), and is secured to the implant with a separate Titanium alloy screw for retention.
The new abutments will all be available with a choice of 3.5mm and 3.9mm implant platform diameters.
#### 5. Indications for Use:
The Zimmer Zfx Titanium Abutment for NobelActive Implant System is designed for use as a terminal or intermediate abutment for cement retained prostheses. The abutment can be used with NobelActive and NobelReplace Conical Connection implants with a Narrow Platform (NP) Ø 3.5mm or a Regular Platform (RP) Ø 3.9mm.
## Device Comparison: 6.
The new abutment device is substantially equivalent to the predicate relative to material, manufacturing process and general design features. It is fabricated from Titanium alloy and utilizes an internal conical connection with hexagonal
{2}------------------------------------------------
interlocking implant/abutment interface, which is identical in size and shape (for a given platform diameter) to the predicate device. The new abutment device will be affixed to the implant by a retaining screw, the same manner as the predicate.

#### 8. Non-Clinical Testing:
Non-clinical test data was used to support the decision of substantial equivalence. This consisted of reverse engineering, compatibility analysis and mechanical fatigue testing. The NobelActive interface was reverse engineered based on actual measurements taken from NobelActive implants, abutments and retaining screws in order to assure that the Zimmer Zfx Titanium Abutmentis compatible with NobelActive and NobelReplace Conical Connection Implant Systems. Dimensional specifications were developed for the Zimmer fabricated components based on the reverse engineering results. A tolerance analysis as well as a rotational analysis was conducted to illustrate the nature of fit between the Zimmer fabricated parts and the OEM implant. To verify the compatibility of the Zimmer device to the OEM device, fatigue testing was completed using Zimmer fabricated abutments assembled to OEM implants in accordance with the FDA guidance Class II Special Controls Guidance Document: Root-form Dental Implants and Endosseous Dental Implant Abutments. The results were
{3}------------------------------------------------
compared to fatigue testing data of the predicate #3 device. Based on the reverse engineering process, as well as verification of the final connection dimensions and tolerances, the Zimmer Zfx Titanium Abutment for NobelActive Implant System can be deemed compatible with the NobelActive and NobelReplace Conical Connection implant interface.
The Zimmer Zfx Titanium Abutment for the NobelActive Implant System will be sold non-sterile and will be sterilized by the end user. The sterilization procedures listed in the Instruction For 'Use were validated to provide a minimum sterility assurance level of 10-6.
Additionally, Zimmer Dental implant systems were evaluated for interactions with magnetic fields during Magnetic Resonance Imaging (MRI) in accordance with the FDA Guidance: Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment. This was done to determine that the presence of the abutment poses no additional restrictions on MRI beyond those that would otherwise occur for the patient.
## 9. Clinical Testing
No clinical testing was performed. Non-clinical testing was used to support the decision of safety and effectiveness.
## 10. Conclusion
Based on our analysis, the device is substantially equivalent to the predicate.
