Intended Use

The SunClear Aligner system is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e. all second molars). SunClear Aligners positions teeth by way of continuous gentle force.

Device Story

SunClear Aligner system consists of series of clear plastic removable orthodontic appliances and proprietary 3D software; alternative to traditional brackets/wires. Dentist/orthodontist performs exam, takes impressions/scans, and sends to lab. Software generates 3D model of final treated state and interpolates intermediate tooth states; clinician reviews, edits, and approves treatment plan. Lab fabricates models and thermoforms aligners. Patient wears each aligner stage for approximately two weeks to apply continuous gentle force for incremental tooth movement. Used in home environment by patient under clinician supervision. Output is physical aligner tray; affects clinical decision-making by providing programmed, staged orthodontic correction.

Clinical Evidence

Bench testing only. No clinical data presented. Flexural strength testing performed on aligner materials to demonstrate equivalence to predicate.

Technological Characteristics

Clear plastic removable orthodontic appliances. Proprietary 3D software for treatment planning. Materials identical to K062828. Manufacturing involves thermoforming aligners over 3D printed models. Connectivity involves digital transfer of dental impressions/scans to lab for processing.

Indications for Use

Indicated for treatment of tooth malocclusion in patients with permanent dentition (all second molars).

#### Device Description:

Orthodontic treatment is conventionally performed using brackets and arch wires. A bracket is bonded to each tooth and a wire is inserted with the goal of moving each tooth to a desired final treatment position. An alternative to traditional bracket treatment has been in existence for the past 20 years. This alternative treatment uses clear plastic aligners to gradually move the teeth. The aligners are designed in a series of incremental stages. A patient wears each aligner stage for a period of two weeks to accomplish the programmed tooth movement. Once tooth movement has been accomplished for a given stage the current aligner is removed and the next aligner in the sequence is worn. This method of orthodontic treatment is popular with patients because it provides a virtually invisible appliance and avoids the appearance of braces on the teeth.

#### Indications for use:

SunClear Aligner system is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e. all second molars). SunClear Aligner positions teeth by way of continuous gentle force.

#### Patient Population:

Patients needing treatment of tooth malocclusion

#### Environments of use: Home

Workflow - The patient actively interacts with the dentist / orthodontist. Interactions include the patient visits a dental office; Dentist/orthodontist completes a comprehensive exam, takes xrays and clears patient for orthodontic treatment; Dentist/orthodontist takes dental impressions or scans of patient and completes diagnostic records and sends to the lab who in turn fabricates models, thermoforms aligners, and sends aligners to the dentist to confirm patient fit.

## Non-Clinical Testing Summary -

Biocompatibility - No testing was performed as the material of the aligners is identical to the K062828 - Dentsply International - Aligner materials which has similar intended use and patient contact.

Bench testing - SunClear Aligners are made of similar aligner material as the predicate. The identified aligner material has been cleared under K06282 for the intended use. We have performed flexural strength of the subject device and predicate materials.

### Substantial Equivalence Conclusion -

The sponsor has demonstrated through performance testing, design and features, and non-clinical testing that the proposed device and predicate have been found to substantially equivalent.
