Analysis of Differences Between Subject Device and Predicate

The On1 Concept and predicate NobelProcera Angulated Screw Channel Conical Connection (K132746) are both two piece endosseous dental implant abutments intended to fit the Nobel Biocare internal conical connection dental implants.

The On1 Concept base is designed to be placed either when the dental implant is placed or with the final abutment. Once placed on the dental implant the On1 Base is not intended to be removed. The predicate NobelProcera Angulated Screw Channel Conical Connection (K132746) base is intended to adapt the abutment post to the internal conical connection implant and is placed along with the post when the definitive abutment is placed.

The On1 Concept components are all fixed design components. The abutments do not have any angulation built in. The predicate NobelProcera Angulated Screw Channel Conical Connection (K132746) abutments are individually shaped and can be angulated.

{6}------------------------------------------------

### Summarv:

The design differences between the subject and predicate devices were evaluated through comparative performance testing. The documentation submitted in the premarket notification demonstrates that the On1 Concept is substantially equivalent to the predicate devices.

# VII. PERFORMANCE DATA

Summary of Non-Clinical Testing:

Since the subject device does not represent a new worst case, data from the predicate device was leveraged in the following aspects of the 510(k).

- Sterile Device Information
- o The sterilization method for the subject device provided sterile is the same as the predicate. The sterilization method is Gamma radiation and has been validated in accordance with ANSI/AAMI/ISO 11137. Therefore, no additional testing was required.
- o The sterilization methods for the subject devices provided non-sterile and to be end user sterilized are pre-vacuum and gravity moist heat sterilization and have been validated in accordance with ANSI/AAMI/ISO 17665-1.
- Device Packaging
- o The packaging for the subject device is the same as the predicate. This is a thermoform tray with peel top lid. Therefore, no additional testing was required.
- Shelf Life -
- The packaging for the subject device is the same as the predicate and o is labeled with a 3-year expiration date. Real time aging was used to determine the expiration dating. Therefore, no additional testing was required.
- Biocompatibility -
- The subject device is manufactured from the same material using the o same manufacturing method as the predicate, has the same intended use, and the same patient contact type and duration. Therefore, no additional testing was required.

The fatigue limit of the On1 Concept was determined using the methods described in ISO 14801. The results of the testing were used to address questions related to substantial equivalence based on difference in design between the subject and predicate devices.

# VIII. CONCLUSIONS

The On1 Concept was evaluated for substantial equivalence using standard and/or comparative testing. In cases where the On1 Concept could be shown to not represent a worst-case with respect to the predicates, data from these predicate

{7}------------------------------------------------

devices was leveraged to support the subject device. Based on technological characteristics and non-clinical test data included in this submission, the On1 Concept has been shown to be substantially equivalent to the NobelProcera Angulated Screw Channel Conical Connection Abutment (K132746).
