Intended Use

Indicated for orthodontic movement of natural teeth, excluding mandibular bicuspid teeth.

Device Description

The Orthodontic Ceramic Bracket is in commercial distribution and consists of a chemically treated base. The modification to the Orthodontic Ceramic Bracket consists of a mechanical lock base and the brackets: are referred to as the Mystique MB Ceramic Brackets. Mystique MB Ceramic Brackets are bonded to teeth to apply pressure to the tooth, transmitted through a flexible orthodontic wire, to alter the tooth position. The mechanical lock base includes rhomboid and "torque-in-the-base" features. The bracket is transparent and has indented walls and is available with or without glass coating in the wire slot.

AI/ML Overview

The provided text does not contain information about acceptance criteria or a study proving device performance in the way typically associated with medical device clinical or performance studies (i.e., sensitivity, specificity, accuracy, etc., for a diagnostic device).

This document is a 510(k) summary for a DENTSPLY Mystique MB Ceramic Brackets, seeking substantial equivalence to a predicate device (K042178). The key points from the document are:

  • Device Description: The Mystique MB Ceramic Brackets are a modification to an existing orthodontic ceramic bracket, primarily involving a mechanical lock base and specific design features (rhomboid, "torque-in-the-base"). The bracket itself is transparent and has indented walls, available with or without glass coating in the wire slot.
  • Intended Use: Indicated for orthodontic movement of natural teeth, excluding mandibular bicuspid teeth. This is explicitly stated to be the same as the predicate device (K042178).
  • Technological Characteristics: The manufacturer claims minor design modification and no changes in intended use or fundamental scientific technology compared to the predicate device. All components have been used in legally marketed devices and/or found safe for dental use. The composition is stated as the same as the predicate device.
  • Justification for Safety and Effectiveness: The manufacturer states that "prior use of the components of Mystique MB Ceramic Brackets in the legally marketed devices, the performance data provided, and previously submitted biocompatibility data support the safety and effectiveness."

Based on this, the 510(k) emphasizes substantial equivalence to a predicate device rather than presenting a performance study with explicit acceptance criteria for a new device's efficacy or diagnostic accuracy. Therefore, most of the requested information regarding acceptance criteria, study design, sample sizes, expert involvement, and ground truth establishment is not available in the provided text.

Here's a breakdown of what can be extracted and what is not available:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria (Inferred from 510k)Reported Device Performance
Biocompatibility: Components are safe for dental use, and composition is same as predicate device."All of the components found in Mystique MB Ceramic Brackets have been used in legally marketed devices and/or were found safe for dental use." "Mystique MB Ceramic Brackets are the same composition as the predicate device. Therefore, further biocompatibility testing is not necessary."
Functional Equivalence: Device performs its intended function (orthodontic movement of natural teeth) similarly to the predicate device despite minor design modifications."Mystique MB Ceramic Brackets represent a minor design modification to K042178. There are no changes in intended use or fundamental scientific technology." "The performance data provided" (specifics not detailed in the summary). Implied to be equivalent based on the 510(k) clearance.
Intended Use: Device is suitable for the same indicated uses as the predicate device."Indicated for orthodontic movement of natural teeth, excluding mandibular bicuspid teeth." "These are the same indications for use previously cleared for K042178."

2. Sample size used for the test set and the data provenance:
* Not available. The document refers to "performance data provided" but does not detail any specific test sets, their sizes, or provenance. This is typical for a 510(k) summary relying on substantial equivalence and previous data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
* Not applicable/Not available. No specific "ground truth" establishment for a test set is described, as this is not a diagnostic device and the clearance is based on substantial equivalence to an existing device.

4. Adjudication method for the test set:
* Not applicable/Not available. No test set or adjudication method is described.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance:
* Not applicable. This device is an orthodontic bracket, not an AI-assisted diagnostic or imaging tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
* Not applicable. This device is an orthodontic bracket, not an algorithm or software.

7. The type of ground truth used:
* Not applicable/Not available. No "ground truth" in the context of diagnostic accuracy is discussed. The "truth" for this device lies in its physical properties, biocompatibility, and ability to facilitate orthodontic movement, which is inferred to be equivalent to the predicate device.

8. The sample size for the training set:
* Not applicable/Not available. No "training set" in the machine learning sense is used or mentioned. The manufacturer relies on prior use of components and existing data.

9. How the ground truth for the training set was established:
* Not applicable/Not available. See point 8.

DEVICE DESCRIPTION: The Orthodontic Ceramic Bracket is in commercial distribution and consists of a chemically treated base. The modification to the Orthodontic Ceramic Bracket consists of a mechanical lock base and the brackets: are referred to as the Mystique MB Ceramic Brackets. Mystique MB Ceramic Brackets are bonded to teeth to apply pressure to the tooth, transmitted through a flexible orthodontic wire, to alter the tooth position. The mechanical lock base includes rhomboid and "torque-in-the-base" features. The bracket is transparent and has indented walls and is available with or without glass coating in the wire slot.

INTENDED USE: Indicated for orthodontic movement of natural teeth, excluding mandibular bicuspid teeth.

(ECHNOLOGICAL CHARACTERISTICS: The Mystique MB Ceramic Brackets represent a minor design modification to K042178. There are no changes in intended use or fundamental scientific technology.

All of the components found in Mystique MB Ceramic Brackets have been used in legally marketed devices and/or were found safe for dental use. Mystique MB Ceramic Brackets are the same composition as the predicate device. Therefore, further biocompatibility testing is not necessary.

We believe that the prior use of the components of Mystique MB Ceramic Brackets in the legally marketed devices, the performance data provided, and previously submitted biocompatibility data support the safety and effectiveness of Mystique MB Ceramic Brackets for the indicated uses.

Dear Ms. Lewis:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
