#### Description of Device:

3MTM Clarity™ Ultra Brackets and Adhesive Coated Appliance System are intended for use in orthodontic treatment. Clarity Ultra Bracket is an esthetic bracket with a sliding door. The brackets are composed of aluminum oxide, which gives them a clear appearance. A nickel titanium wire serves as part of the door mechanism and is attached to the bracket using a cured adhesive. The brackets incorporate a water-soluble color placement indicator system. The archwire slot, vertical slot, and door are marked to facilitate bracket positioning. Tie wing(s) and/or door are color coded with dots to facilitate bracket identification. The brackets are available with or without APC™ Flash-Free pre-coated adhesive. The pre-coated adhesive ensures a consistent amount of adhesive on the bracket.

#### Indications for Use:

3M™ Clarity™ Ultra Brackets and Adhesive Coated Appliance System are intended for use in orthodontic treatment. The brackets are affixed to teeth so that pressure can be exerted on the teeth.

#### Performance Testing:

Bench testing consistent with the clinical application and intended use was used to evaluate the performance of Clarity™ Ultra Self-Ligating Brackets and Adhesive Coated Appliance System compared to the predicate devices, Clarity™ Advanced and Damon 4Clear. Properties evaluated include: rotation play angle, wire rotation strength, shear-peel bond strength, torque strength, and squeeze debond strength. 3M Health Care has tested Clarity™ Ultra Self-Ligating Brackets and Adhesive Coated Appliance System and has concluded that the performance tests results demonstrate substantial equivalence to the predicate devices.

#### Technological Characteristics:

Clarity Ultra Brackets are substantially equivalent in design feature to the predicate devices. Clarity Ultra, Clarity Advanced, and Damon 4Clear brackets all have a bracket body made of ceramic. Clarity Ultra and Damon 4 Clear both have a self-ligating ceramic door with a nickeltitanium spring mechanism. Clarity Ultra and Clarity Advanced both have a water-soluble placement indicator system and a glass-grit bonding base that can be pre-coated with APC Flash-Free adhesive.

#### Mechanism of Action:

Clarity Ultra Brackets are substantially equivalent in mechanism of action to the predicate devices. Clarity Advanced and Damon 4Clear brackets. Orthodontic brackets are affixed to teeth using an orthodontic adhesive. Pressure is exerted on a tooth when the brackets are used in combination with archwires and/or other intraoral modules. The pressure causes tooth movement.

Clarity Ultra and Damon 4Clear brackets both have a self-ligating mechanism that ligates the archwire and secures it inside the bracket's wire slot instead of using a manually-placed elastomeric or steel ligature.

Clarity Ultra and Clarity Advanced brackets can be pre-coated with APC Flash-Free adhesive. The methacrylate functionalities of the APC Flash-Free adhesive resins and surface-treated

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

fillers undergo a light-induced polymerization to form a hard composite that bonds the orthodontic appliance to a tooth and can be removed at the completion of the orthodontic treatment.

## Biocompatibility Testing:

The biocompatibility evaluation for the device was conducted in accordance with the FDA Guidance Docket Number FDA-2013-D-0350 and International Standard ISO 10993-1:2009 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. 3M™ Clarity™ Ultra Self-Ligating Brackets and Adhesive Coated Appliance System are considered mucosal membrane contacting for a duration of greater than 30 days. The following are some of the evaluated endpoints:

- . Cytotoxicity
- Sensitization ●
- Irritation ●
- Systemic Toxicity ●
- Pyrogenicity ●
- Genotoxicity ●

The results of the evaluation met the requirements of internationally recognized guidelines as mentioned above and further support a determination of substantial equivalence.

2 Not Available, details not disclosed by manufacturer

Clarity Ultra Brackets have substantially equivalent Indications for Use as the identified predicate devices. The verbiage of the Indications for Use of the subject device is slightly different than the predicate devices; however these slight differences do not alter the intended therapeutic use of the device as compared to the predicates.

The technological characteristics, how the device functions, and the mechanical properties of Clarity Ultra Brackets compared to the predicates have not fundamentally changed. Orthodontic brackets are designed to be affixed to teeth and to hold an archwire so that pressure can be exerted to move the teeth to new positions. Bench testing shows that Clarity Ultra Brackets are substantially equivalent in performance to the predicate devices.

#### Conclusion

3M™ Clarity™ Ultra Brackets and Adhesive Coated Appliance System are substantially equivalent to the predicate devices in terms of intended use, indications for use, design, performance, technological characteristics, mechanism of action, composition, and biocompatibility.
