This air-powered dental handpiece is intended for removal of carious material, cavities and crown preparations, removal of filings, processing of tooth, restoration of surfaces and as a surgical tool for third molar removal procedures. It is designed for use by a trained professional in the field of general dentistry.

Device Description

The TRAUS Air Dental handpieces are air driven dental handpieces for the use by a trained dental professional. The devices are air-powered handpieces that are reusable and designed accordance with international standard. The devices can be sterilized by the prevacuum steam autoclave methods that have been validated. Through the coupling connected to a dental unit, the proposed dental handpiece receive air for functionality of the high-speed turbine. They also receive cooling water for cutting through one port and light for illumination through another port.

Using in combination with dental unit chair, it is possible to use by installing the instrument at air handpiece according to purpose. It is possible to change the rotation speed by adjusting the flowing air.

AI/ML Overview

The provided document is a 510(k) premarket notification for a dental handpiece (TRAUS Air Dental Handpiece) and does not contain information about acceptance criteria and a study proving a device meets those criteria in the context of an AI/ML medical device.

The document discusses the substantial equivalence of the TRAUS Air Dental Handpiece to a predicate device (Maxima PRO 45L) based on technical characteristics and non-clinical performance data. It explicitly states: "No clinical performance testing was performed."

Therefore, I cannot provide the requested information, such as:

Table of acceptance criteria and reported device performance: This document does not establish performance criteria in the way an AI/ML device study would (e.g., sensitivity, specificity, AUC). Instead, it compares the technical specifications and operational principles of the new device to a predicate device.
Sample size, data provenance, number of experts, adjudication method, MRMC study, standalone performance: These are all concepts relevant to clinical or AI/ML performance studies, which were explicitly stated as "not performed."
Type of ground truth: Not applicable as it's a mechanical device with no AI component requiring ground truth.
Sample size for training set, how the ground truth for the training set was established: Not applicable as there is no training set for an AI/ML model.

The "Non-clinical Performance Data" section (page 6) details bench tests conducted to ensure conformity to ISO standards (ISO 14457, ISO 17665-1, ISO 9168) and demonstrate substantial equivalence. These are engineering and sterilization validation tests, not performance studies as typically understood for AI/ML devices.

In summary, the provided text describes a 510(k) submission for a conventional dental handpiece, and thus does not contain the information requested about acceptance criteria and a study for an AI/ML driven device.

Dear Sanghwa Myung:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

{1}------------------------------------------------

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
