Intended Use
The Clear Aligners indicated for use in the alignment of permanent teeth (i.e. all second molars) through orthodontic treatment of misalignment and malocclusion.
Device Description
The Clear Aligners are intraoral thermoformed plastic aligners that are worn 22 hours per day and are designed to be used in a sequence, each aligner providing a gentle continuous force, to allow for the movement of teeth to the final desired position. The aligners are to be removed for eating and for cleaning. The Clear Aligners are fabricated using a three-step process. The first step is to obtain the dimensions and details of the patient's baseline dentition. This is generally done using an oral scan data or a physical impression. This scanned data (digital CAD/CAM models or patient models) are imported into specialized dental software for treatment planning. The second step is the printing of 3D models of the treatment plan for use in step 3 (thermoforming). In the second step, the doctor utilizes a software application to plan the treatment by creating a series of sequential models that gradually position the their final desired position. A 3D printer is used to create the molds needed for each treatment step to provide the surface around which the aligner is thermoformed. The final step is the thermoforming of a plastic sheet material to each of the sequential treatment steps. This process is done using a standard thermoforming equipment and the appropriate material as outlined in this submission.
More Information

Not Found

No
The description focuses on the physical manufacturing process and software for treatment planning, without mentioning AI/ML for analysis or decision-making.

Yes

The device, Clear Aligners, is designed to align permanent teeth through orthodontic treatment to correct misalignment and malocclusion, directly addressing a health condition.

No

The device is an orthodontic treatment device used for the alignment of teeth, not for diagnosing any medical condition. It moves teeth to a desired position rather than identifying or characterizing a disease or condition.

No

The device description clearly states that the device is an intraoral thermoformed plastic aligner, which is a physical hardware component. While software is used in the manufacturing process, the final device is not software-only.

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

Here's why:

  • Intended Use: The intended use is for the "alignment of permanent teeth... through orthodontic treatment of misalignment and malocclusion." This describes a therapeutic intervention on the patient's body, not a diagnostic test performed on a sample taken from the body.
  • Device Description: The device is an "intraoral thermoformed plastic aligner" that is worn by the patient. It is a physical device used to apply force to teeth.
  • Lack of Diagnostic Function: The description focuses on the process of creating the aligners based on patient data (scans or impressions) and a treatment plan. There is no mention of the device being used to diagnose a condition or provide information about a patient's health status based on in vitro analysis.
  • Anatomical Site: The device acts on "permanent teeth," which is a part of the patient's body, not a sample taken from the body.

IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for the diagnosis, monitoring, or treatment of a disease or condition. This device does not fit that description.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-clinical tests have been conducted to verify that the Clear Aligner meets all design specifications which supports the conclusion that it's Substantially Equivalent (SE) to the predicate device.

Manufacturing Validation Accuracy Testing:
A manufacturing validation was performed to demonstrate the manufacturing process for Clear Aligner. Three critical aspects of the manufacturing process were assessed: digital dentition models from treatment planning, 3D printed molds, and the final thermoformed aligner.
An independent 3rd party software and digital calipers were used to perform point-to-point measurement. All translational measurements were within 0.3mm of the target input value, the predefined tolerance of the manufacturing process. There were no statistical differences in the difference in the intended and measured values observed from any of the groups. This test has met the pre-established acceptance criteria.
The results of the manufacturing validation accuracy testing support a determination of substantial equivalence.

Biocompatibility Testing:
The biocompatibility evaluation for the device was conducted in accordance with "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 Clear aligner is considered surface contacting for a duration of greater than 30 days. The testing included the following tests: Cytotoxicity, Irritation, Sensitization.
The results of the testing met the requirements of the study protocol 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.

Clinical Test:
No clinical study is included in this submission.

510 (K) Number: K201450 Straight T Clear Dental Aligner Produced by Straight T, Inc.

Indication for use:

The Clear Aligners indicated for use in the alignment teeth (i.e. all second molars) through orthodontic treatment of misalignment and malocclusion.

Device Description

The Clear Aligners are intraoral thermoformed plastic aligners that are worn 22 hours per day and are designed to be used in a sequence, each aligner providing a gentle continuous force, to allow for the movement of teeth to the final desired position. The aligners are to be removed for eating and for cleaning.

The Clear Aligners are fabricated using a three-step process.

The first step is to obtain the dimensions and details of the patient's baseline dentition. This is

generally done using an oral scan data or a physical impression. This scanned data (digital CAD/CAM models or patient models) are imported into specialized dental software for treatment planning.

The second step is the printing of 3D models of the treatment plan for use in step 3 (thermoforming). In the second step, the doctor utilizes a software application to plan the treatment by creating a series of sequential models that gradually position the their final desired position. A 3D printer is used to create the molds needed for each treatment step to provide the surface around which the aligner is thermoformed.

The final step is the thermoforming of a plastic sheet material to each of the sequential treatment steps. This process is done using a standard thermoforming equipment and the appropriate material as outlined in this submission.

Software Description

Specialized orthodontic CAD/CAM software will be used to develop the treatment plans and to produce standard 3D printer files that will facilitate the manufacturing of each sequential aligner in the treatment plan. The software application used for the manufacturing validation in this submission is the 3Shape®.

Mechanism of Action

In the same manner as the predicate device, each aligner exerts gentle force to achieve progressive realignment of the teeth until the final correction has been attained. This is based on the treatment plan and proceeds over time.

Comparison with predicate

A summary comparison of features is provided in the following Table:
