Multi Unit Abutment Plus

The Multi-unit Abutment Plus are transmucosal abutments used for multiple unit screw retained restorations. The abutment family consists of straight and angled abutments in varying collar heights. The non-angled abutments have a built in screw and the angled abutments are co-packed with a separate abutment screw. The Multi-unit Abutment Plus is compatible with the Nobel Biocare dental implants that have the internal conical connection.

## VI. Comparison of Technological Characteristics

{5}------------------------------------------------

Analysis of Differences Between Subject Device and Predicate

The Multi-unit Abutment Plus is an evolution of the predicate NobelActive Multi Unit Abutment. It differs from the predicate in the addition of a Wide Platform (WP) abutment (K133731, NobelActive WP, as a reference predicate) and through integration of a snap coping feature. The snap feature, when used with corresponding coping, facilitates try-in by allowing the provisional restoration to be positioned without using screws. Once fitting of the restoration is completed the restoration is secured with prosthetic screws.

## Summary:

The documentation submitted in the premarket notification demonstrates that the Multi Unit Plus is substantially equivalent to the predicate device. Differences in technology were evaluated through comparative performance testing.

# 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 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 Temporary Snap Coping is delivered non-sterile. A sterilization validation was performed to ensure sterility of the subject device when processed by the end user. Sterilization validations were performed using fractionated pre-vacuum and gravity displacement. Sterilization validations were performed with the worst case dental devices.
- Device Packaging -
- The packaging for the subject device is the same as the predicate. O 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.

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

- Biocompatibilitv
- o The subject device is manufactured from the same material as the predicate (K072570, Nobel Biocare), uses the 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 Multi-unit Abutment Plus was determined using a modified version of ISO 14801. The modifications to ISO 14801 were done to reflect the likely worst-case clinical use of the device. Both the subject and predicate device were tested under identical conditions. The results of the testing were used to address questions related to substantial equivalence based on difference in design between the subiect and predicate devices.

# VIII. CONCLUSIONS

The Multi-unit Abutment Plus was evaluated for substantial equivalence using standard and/or comparative testing. In cases where the Multi-unit Abutment Plus could be shown to not represent a worst-case with respect to the predicates, data from these predicate devices was leveraged to support the subject device. Based on technological characteristics and non-clinical test data included in this submission, the Multi-unit Abutment Plus has been shown to be substantially equivalent to the NobelActive Multi Unit Abutment (K072570).
