Intended Use

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

Device Story

The Byte Aligner System is a series of clear, thermoformed PETG aligners used for orthodontic tooth movement. Treatment plans are generated using CAD-CAM software; model archforms are created via rapid prototyping (stereolithography). Aligners are thermoformed over these models. The device is prescribed by dental clinicians. Patients wear the aligners 20-22 hours daily, replacing them in a sequential series to apply continuous gentle force to teeth and roots, causing pressure to the periodontium to achieve incremental repositioning. The system supports the use of attachments, cut-outs, and slits to facilitate specific tooth movements. The device is non-sterile and intended for single-patient, multiple-use.

Clinical Evidence

No clinical data included. Substantial equivalence is supported by bench testing, literature review, and comparison to predicate/reference devices.

Technological Characteristics

Materials: PETG (copolyester) plastic sheets. Principle: Orthodontic tooth movement via continuous gentle force from elastic deformation of thermoformed aligners. Form factor: Sequential series of custom-fit trays. Manufacturing: Thermoforming over 3D-printed model archforms. Connectivity: None. Sterilization: Non-sterile.

Indications for Use

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

Regulatory Classification

Identification

#### 4. Description of Device:

The Byte Aligner System consists of a sequential series of aligners fabricated of clear, thin, lightweight and flexible thermoformed polyethylene terephthalate glycol (PETG) [copolyester] plastics.

The mechanism of action of the proposed Byte Aligner System is mechanical in nature; that is, tooth movement induced by orthodontic force application using continuous gentle forces. The aligners are made from elastic thermoplastic material that applies continuous gentle force to the teeth for treatment of tooth malocclusion. Treatment plans are modeled using CAD-CAM (computer-aideddesign and computer-aided-manufacturing) software. Model archforms are created using rapid prototyping techniques like stereo-lithography. The aligners are thermoformed over the model archforms and are not themselves 3D printed.

With the aligners seated on the patient's upper and/or lower dental arches, the teeth are progressively and gradually straightened over time by mechanical forces that are delivered via minor, incremental changes in tooth positions in each subsequent set of aligner trays that have been customized for the patient, delivered as a sequential series of trays to progressively reposition the teeth. The mechanics of how this happens is based on the forces caused by the elastic deformation of the aligner when worn by the patient. The forces are applied to the teeth, and also to the roots, causing pressure to the periodontium in the direction of the desired movement. Each aligner moves the patient's teeth in small increments from their original state.

- న. Indications for Use:
The Byte Aligner System is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e., all second molars). The Byte Aligner System positions teeth by way of continuous gentle force.

#### 6. Comparison of Technological Characteristics:

The purpose of this Traditional 510(k) is to gain U.S. premarket clearance for the modification to the predicate device Byte Aligner System (K180346).

- . The proposed and predicate device have the same intended use, patient population and indications for use.
- The proposed and predicate devices are made by thermoforming PETG (copolyester) plastic sheets.
- The proposed and predicate devices have the same packaging configurations. ●

The key differences between the predicate device (K180346) and the proposed device are:

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

- The proposed device can be made by thermoforming additionally cleared PETG (copolyester) ● plastic sheets (K062828), and which follows the same manufacturing processes and materials as reference device Sureclear Aligners (K171860).
- . Reference to two additional cleared orthodontic software systems (K213916, K171860) that can be used for treatment planning software prior to the fabrication of the proposed device.
- Revise product label to only include date of manufacture and exclude an expiration date to be . consistent with the reference device Sureclear Aligners (K171860).
- Separate Instructions for Use for patient and doctor. Update patient Instructions for Use to be . more aligned with requirements in FDA guidance document, "Guidance on Medical Device Patient Labeling". Create separate Instructions for Use geared towards the dentist.
- . Allow for the use of cut-outs, slits and attachments similar to the reference devices (K181739 and K182826).

An overview of the similarities and differences between the proposed devices, predicate device, and reference devices is given in Table FS.1.

#### 7. Non-Clinical Performance Data

Testing data that was referenced, or data relied upon to demonstrate substantial equivalence include:

- a) Biocompatibility evaluation in accordance with EN ISO 10993-1:2018 (Biological evaluation of medical devices – Part 1: Evaluation and testing with a risk management process) was performed and it was determined that no additional testing was required to demonstrate biological safety of proposed devices. Testing on file in Sureclear Aligners (K171860) remains valid.
- b) Shelf-life information included in Mouthguard and Aligner Materials (K062828) and Sureclear Aligners (K171860) was reviewed, in addition to literature, and considered to be sufficient evidence to support the addition of alternate PETG (copolyester) materials and modification to the finished device shelf-life.
- c) Literature and material data sheet review was performed on the predicate device (K180346) PETG polyester materials and the proposed PETG polyester materials and confirmed that the materials are very similar in characteristics and performance.

#### 8. Clinical Performance Data

No data from human clinical studies was included to support the substantial equivalence of the proposed Byte Aligner System.

#### 9. Conclusion

The information included in this Traditional 510(k) supports the substantial equivalence of the proposed Byte Aligner System with the predicate device Byte Aligner System (K180346). The proposed device has the same intended use and indications for use as the predicate device, and is an aligner system fabricated by thermoforming PETG (copolyester) plastics that induce tooth movement by orthodontic force application using continuous gentle forces.

The proposed device represents an extension of predicate device Byte Aligner System (K180346) by allowing for the addition of alternate PETG (copolyester) materials to be used for manufacturing of aligners and removing the shelf life of the device based on the nature of the Byte Aligner System and well-known polymer science. The technological differences between the predicate device Byte Aligner System (K180346) and the proposed device are supported with the data included in premarket notifications of reference devices Sureclear aligners (K171860) and Mouthguard and Aligner materials (K062828) and additional data provided in this submission in support of the equivalency between the polyester materials. In addition, this premarket submission incorporates slits and cut-outs into the aligner and allows for the use of attachments which is similar to the additional reference devices (K181739, K182826).

Based on the intended use, indications for use, and technological features comparison, and the review of literature, data on file, and testing by reference, it can be concluded that the proposed Byte Aligner System is substantially equivalent to the predicate device Byte Aligner System (K180346).
