Intended Use

The 3MM Clear Tray Aligner system is a series of clear, lightweight, plastic appliances indicated for the treatment of tooth malocclusions in patients with permanent dentition (i.e., all second molars). Utilizing a series of incremental tooth movements, it sequentially positions teeth by way of continuous gentle force.

Device Description

The 3M Clear Tray Aligner System is a series of clear plastic aligners that offer a solution for patients who want an aesthetic orthodontic treatment by utilizing a set of removable aligners to correct tooth malocclusions without the use of conventional wire and bracket orthodontic technology. A dental health professional (e.g. orthodontist or dentist), using a standard personal computer prescribes the 3M Clear Tray Aligner 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 using a standard dental software used for tooth alignment, 3M then designs a series of plastic travs intended to gradually realign the patient's teeth in accordance with the physician's prescription using a standard dental software used for tooth alignment. The prescribing physician reviews and approves the model scheme before the molds are produced. Once approved, 3M produces trays, which are formed of clear, thin, thermoformed plastic. The trays are sent back to the dental health care professional who then provides them to the patient, confirming fit and design. Over a period, additional trays are provided sequentially to the patient by the dental health professional 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 any time.

AI/ML (Artificial Intelligence / Machine Learning)

No
The description explicitly states the use of "standard dental software" and does not mention any AI/ML components in the design or manufacturing process.

Therapeutic

Yes
The device is indicated for the treatment of tooth malocclusions, which is a medical condition, and it functions by sequentially positioning teeth using continuous gentle force, thereby providing a therapeutic effect.

Diagnostic

No

The device is described as a system for treating tooth malocclusions by gradually repositioning teeth. It is used to implement a course of treatment determined by an "assessment of the patient's teeth" by a dental professional, but it does not perform the assessment or diagnosis itself.

SaMD (Software as a Medical Device)

No

The device description clearly states that the device is a series of clear plastic aligners, which are physical objects, not software. While software is used in the design process, the final medical device provided to the patient is a physical product.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

• IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
• Device Function: The 3M Clear Tray Aligner system is a physical appliance used to mechanically move teeth. It does not analyze any biological samples from the patient.
• Intended Use: The intended use is for the treatment of tooth malocclusions, which is a mechanical correction, not a diagnostic process based on analyzing biological specimens.

The device description clearly outlines a process involving dental professionals, molds of teeth, software design, and physical trays applied to the teeth. This aligns with a therapeutic device for orthodontic treatment, not an IVD.

Indications for Use:

The 3M Clear Tray Aligner System is a series of clear, lightweight, plastic appliances indicated for the treatment of tooth malocclusions in patients with permanent dentition (i.e. all second molars). Utilizing a series of incremental tooth movements, it sequentially positions teeth by way of continuous gentle force.

Predicate Devices:

Invisalign® System (K081960) [Primary Predicate] ClearCorrect System (K113618) [Predicate Device]

Description of Device:

The 3M Clear Tray Aligner System is a series of clear plastic aligners that offer a solution for patients who want an aesthetic orthodontic treatment by utilizing a set of removable aligners to correct tooth malocclusions without the use of conventional wire and bracket orthodontic technology.

A dental health professional (e.g. orthodontist or dentist), using a standard personal computer prescribes the 3M Clear Tray Aligner 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 using a standard dental software used for tooth alignment, 3M then designs a series of plastic travs intended to gradually realign the patient's teeth in accordance with the physician's prescription using a standard dental software used for tooth alignment. The prescribing physician reviews and approves the model scheme before the molds are produced. Once approved, 3M produces trays, which are formed of clear, thin, thermoformed plastic. The trays are sent back to the dental health care professional who then provides them to the patient, confirming fit and design. Over a period, additional trays are provided sequentially to the patient by the dental health professional to gradually move the target teeth to the designed position. The dental care professional monitors treatment from the moment

5

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 any time.

The technology is essentially identical to that used by a number of sequential aligner systems including the predicates referenced in Table #1.

Technological Characteristics:

Treatment of tooth malocclusions via a series of plastic appliances that incrementally moves teeth to a desired end-state is the technological principle for both the subject and predicate devices. A comparison between the technological characteristics of the 3M Clear Tray Aligner and that of legally marketed predicate devices has been performed. The results of this comparison demonstrate that the design, technology, materials and composition of the 3M Clear Tray Aligner are substantially equivalent to the predicate devices.

Mechanism of Action:

The mechanism of action is similar to the predicate devices and supports a determination of substantial equivalence. Orthodontic tooth movement occurs through forces applied by the appliance to the dentition as each tooth follows the programmed displacement based on a dental health professional's prescription.

Performance Testing

Although, bench testing was not performed due to the difficulty in evaluating this type of dental device in a laboratory setting: translucency testing, shelf life and life expectancy tests were conducted on the thermoformed tray material which showed acceptable translucency properties and shelf life requirements for all tested samples.

There is sufficient information available from the scientific literature and from the predicate devices to demonstrate that sequential aligners provide reasonable assurance of safety and effectiveness.

Biocompatibility Testing

The biocompatibility evaluation for the device was conducted in accordance with the US FDA Docket Number FDA-2013-D-0350. CDRH Document Number 1811 "Use of International Standard ISO 10993-1. Biological evaluation and testing within a risk management process -Guidance for Industry and Food and Drug Administration Staff" as recognized by FDA. The aligner is considered mucosal membrane contacting for a duration of greater than 30 days. The battery of testing included the following tests:

• Cytotoxicity .
• Sensitization .
• Irritation ●

The results of the testing met the requirements of the study protocols and the material is considered non-cytotoxic, non-sensitizing and is not an intracutaneous irritant. The results of the studies further support a determination of substantial equivalence.

Software Verification and Validation Testing

Software verification and validation testing were conducted on the software that facilitates ordering and processing of the 3M Clear Tray Aligner to support that the device is as safe and effective as the predicates. Documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern.

Substantial Equivalence Conclusion:

The Clear Tray Aligner has substantially equivalent Indications for Use as the identified predicate devices. The verbiage of the Indications of Use of the subject device is slightly different than the declared predicates; however, these slight differences do not alter the intended therapeutic use of the device as compared to the predicates.

The conclusions drawn from the data included in this submission, demonstrates that the 3M Clear Tray Aligner is as safe, as effective, and is substantially equivalent to the predicate devices in indications for use, design, technological characteristics, mechanism of action, performance, materials and biocompatibility.
