### DEVICE DESCRIPTION

The Clear Moves Aligner is a series of clear, light weight thermoformed plastic aligners designed to be worn in sequence to facilitate the movement of the teeth to the final desired position. The sequential aligners introduce increments that move teeth by way of gentle continuous force. The aligners are to be worn 20 to 22 hours a day and are to be removed for eating and for cleaning. Generally the typical wear time for each aligner is a two weeks duration prior to being replaced by the next aligner in sequence.

A digital or traditional mold impression of the patient's dentition is provided by a dental health professional (e.g. orthodontist or dentist). From the digital data of the patient's dentition, a specialized orthodontic CAD/CAM software is used to develop treatment plan. Using the software, dental technicians design a series of intermediate models

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

corresponding to each stage of treatment, gradually realigning the patient's teeth according to the dental health profession's prescription.

The prescribing doctor reviews and approves the model scheme and treatment plan before the molds/models are produced.

Once approved. the specialized orthodontic software is used to generate standard format 3D files which are used to physically produce each model/mold in the treatment plan for aligner fabrication. Space Maintainers Laboratories produces the aligner trays by thermal forming a plastic sheet over each model in the treatment plan. The trays are provided to the dental health care professional who provides them to the patients in sequential stages, confirming fit and design. The dental health professional monitors treatment from the moment of the first aligner is delivered to when the final aligner is finished and treatment is complete. The aligners are held in place by pressure and can be removed by the patient at any time.

# INDICATIONS FOR USE

The Clear Moves Aligners are indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e. all second molars). The Clear Moves Aligners position teeth by way of continuous gentle force.

### Substantial Equivalence Discussion:

The indications of use of the Clear Moves aligners is same as the predicate device. Slight difference in wording will not affect the intended use of the devices as they are both intended for correcting dental malocclusion patients with permanent dentition.

The subjective has very similar technological characteristics as to the predicate device in material, principle of operation, manufacturing process, design and clinical application. The only difference compared to Clear Moves Aligner with the predicate device is the software used to treatment planning and creation of models/mold. However both software are FDA cleared, under product code PNN for its intended use, which will not affect substantial equivalence of safety and effectiveness.

Therefore, the Clear Moves Aligner is considered to be substantially equivalent to the predicate device based on a comparison of intended use and technological characteristics.

### Non-Clinical PERFORMANCE DATA

Non-clinical testing have been conducted to verify that the Clear Moves Aligner meets all design specification which supports the conclusion that it's substantially equivalent (SE) to the predicate device.

Software used for treatment planning and creation of models/mold for Clear Moves Aligner is Guiemia Ortho + manufactured by Guidemia Technologies. LLC. It is a 510(K) clearance (K162850) software under product code PNN for intended use.

An internal manufacturing validation was performed to demonstrate the dimensional accuracy of the manufacturing for Clear Moves Aligner. The critical aspects of the manufacturing process were assessed for accuracy. The final aligner fitness was evaluated according to the in-house fitness acceptance criteria.

{8}------------------------------------------------

Translational measurement were within 0.150mm (150microns) of the target input value, the predefined tolerance of the manufacturing process. The testing results are within the acceptance criteria to demonstrate dimensional accuracy. Additionally, the final aligner fitness evaluation by a trained physician demonstrate all the aligners including in the study passed and were deemed an excellent fit .

The biocompatibility evaluation determined that Clear Moves Aligner and the predicate devices are composed of the same material, fabricated by the similar manufacturing processes, and has identical method of use, which can conclude that Clear Moves Aligners are biocompatible for its intended use.

Biocompatibility testing for the aligner material, the only patient contacting material, was conducted by the material manufacture in accordance with International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process".

### CLINICAL PERFORMANCE DATA

The clinical performance of sequential aligners (product code NXC) has been well established since the first device of this category was cleared by the FDA in 1998. The Clear Moves aligners have equivalent indication and method of use to its predicate, therefore there was no clinical testing necessary to support this device.
