## Predicate Device

Invisalign® System (K081960)

## General Description

eCligner® is a transparent and removable orthodontic appliance.

eCligner® is a digitally- made Clear Aligner by the 3DCAD/CAM system. By printing the completed setup data into a series of plastic models, eCligne® is produced by a simple stamping procedure (Vacuum forming). eCligner® is designed for orthodontic tooth movement.

Each step for using orthodontic appliance, eCligner® consists of 3 weeks (1 week for soft, 1 week for medium and 1 week for hard) and wearing the appliance 17 hours a day for each sequence is required. * More than 3 weeks of wearing may be required per step depending on the direction of orthodontic treatment and dentist's instruction.

{4}------------------------------------------------

* eCligner® -H is used for 3 weeks during Final process.

During one individual step of treatment, three aligners of different layer thickness are worn in weekly intervals. The applied layer thicknesses are 0.5 mm (medium) and 0.75 mm (hard). Each individual step is consisting of three different thickness appliances as follows:

- 1. eCligner® -S (Soft)
- 2. eCligner® -M (Medium)
- 3. eCligner® -H (Hard)

*eCligner® -UH (Ultra Hard, 1.00mm) is used only for the patient with Bruxism (Teeth Grinding) since the aligner can be broken while the patient grinds their teeth unintentionally.

#### Indication for Use

eCligner® is a series of clear, lightweight, plastic appliances indicated for the correction of dental malocclusion in patients with permanent dentition (i.e.all second molars). The eCligner® is intended for minor anterior tooth movement by way of continuous gentle force.

#### Mechanism of Action

Each eCligner® exerts gentle force to achieve progressive realignmen to the teeth until the final correction has been attained.

## Summary of Technological Characteristics

A dental health care professional (e.g. orthodontist or dentist), prescribes the eCligner system based on an assessment of the patient's teeth, determines a course of treatment with the system, takes molds of the patient's teeth, and completes a prescription form, eCligner designs a series of plastic trays intended to gradually realign the patient's teeth in accordance with the physician's prescribing physician reviews and approves the model scheme before the molds are produced. Once approved, eCligner produces the trays, which are formed of clear, thin, thermoformed plastic. The trays are sent back to the dentist who then provides them to the patient, confirming fit and design. Over a period, additional trays are provided sequentially to the patient by the physician to gradually move the target teeth to the designed position. The dental care professional monitors treatment from the moment the first aligner is delivered to when the final aligner is delivered. The trays are held in place by pressure and can be removed by the patient at anytime.

The technology is essentially identical to that used by a number of sequential alignment systems including the predicate device.

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

#### Performance Testing

Biocompatibility tests such as cytotoxicity, irritation, and sensitization were performed in accordance with ISO 10993.

In addition, software validation test for CAD/CAM system used to fabricate this subject device was performed according to Guidance for Industry and FDA Staff, Guidance for the content of premarket submissions for software contained in medical devices. A performance qualification of the available software utilized in the processing steps of the subject device has been included to support substantial equivalence.

## Comparison to the Predicate Devices

The subject device is substantially equivalent to the following predicate devices:

- K081960, Invisalign system manufactured by Align Technology.

{7}------------------------------------------------

#### Substantial Equivalence Discussion

The eCligner® has a substantially equivalent intended use as the identified predicate. The subject device is similar in fundamental scientific technology to the predicate device in that they all have been designed, manufactured and tested in compliance with 21 CFR 872.5470.

The subject and predicate devices are similar in indications, design, mechanism of action and materials.

The difference between the subject device and the predicate device is the aligners with various layer thicknesses. The subject device needs three steps of treatment with 0.5 mm (soft), 0.62 mm (medium) and 0.75 mm (hard) thickness.

The verbiage of the Indications for Use of the subject device is slightly different than that of the declared predicates; however, these slight differences in wording does not change the intended use of the subject device has compared to the declared predicate.

Any differences in technology characteristics are accompanied by information that demonstrated the device is as safe and as effective as the predicate and do not raise different questions of safety and effectiveness than the predicate.

#### Conclusion

Testing to demonstrate the acceptability of the software utilized in the treatment planning steps has been included to support substantial equivalence. Based on the similarities of the two devices, it is concluded that the eCligner® is substantially equivalent to the predicate device.
