## VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS

Analysis of Differences Between Subject Device and Predicate

The subject device Healing Cap Multi-unit Titanium is a single-piece healing cap made entirely of titanium alloy (ASTM F-136). The predicate Nobelpharma Branemark System - Healing Cap (K925780) has both one-piece healing abutments made entirely of CP titanium and two-piece designs made of plastic with integrated stainless steel screws.

Both subject and predicate devices are intended to be connected to the dental abutment as temporary components during soft tissue healing. The Healing Cap Multi-unit Titanium has a maximum intra-oral use of 180-days.

Nobel Biocare Traditional 510(k) Notification Healing Cap Mu Ti April 2017

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

The subject healing caps are available in three diameters to fit the compatible abutments and two heights that allow the dentist to adapt to the existing soft tissue. The predicate single-piece healing cap is available in only one diameter and height combination. Details regarding the available sizes are in the table above.

The subject healing cap is made of titanium alloy Ti6Al4V ELI (ASTM F136). The predicate single-piece healing Cap is made entirely of commercially pure titanium. The use of titanium alloy will not have an impact on the use of the healing cap.

### Summary:

The documentation submitted in the premarket notification demonstrates that the Healing Cap Multi-unit Titanium is substantially equivalent to the predicate device.

### 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 -
- The sterilization method for the subject device is the same as the reference o predicate. The sterilization method is Gamma radiation and has been validated in accordance with ANSI/AAMI/ISO 11137. Therefore, no additional testing was required.
- -Device Packaging
- The packaging for the subject device is the same as the reference predicate. o This is a thermoform tray with peel top lid. Therefore, no additional testing was required.
- -Shelf Life
- o The packaging for the subject device is the same as the reference predicate and 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 as the reference o predicate, 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.

## VIII. CONCLUSIONS

The Healing Cap Multi-unit Titanium was evaluated for substantial equivalence using standard and/or comparative testing. In cases where the Healing Cap Multi-unit Titanium 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, the Healing Cap Multi-unit Titanium has been shown to be substantially equivalent to the NobelPharma Branemark System Healing Caps (K925780).
