The Integral Dental Unit is intended to supply power to and serve as a base for dental devices and accessories. This device includes a dental chair and is intended for use in the dental clinic environment and is designed for use by trained dental professionals, dentists and/or dental assistants.

Device Description

The Integral Dental Unit (Model: YD-A4) is a dental operative unit specially designed and provided for a qualified dentist to be used in a professional clinic or hospital facility to carry out dental procedures.

Integral Dental Unit is intended to be used in a professional environment for dental diagnosis, treatment, or operation.

It includes a treatment chair, dentist element, assistant element and a dental light as offering several additional options and electronically-controlled chair movements with software and water/air unit functions.

The dental unit consists of an electronically operated dental chair and integrated control unit control for electricity, water and air supply to handpieces or some other dental instrument. The device is equipped with an instrument tray, pipes for water supply and tube air supply, a mouth lamp, a saliva aspirator, a spittoon, a three-way syringe, a film viewer, a foot switch and chair with driving motors and armrest.

The dental chair is intended to be used with dental hand pieces, cure light, ultrasonic scaler, camera system or other doctor stool, which is not provided by the manufacturer. The user will select the dental instruments and accessories with FDA clearance by themself. So, the device in the submission does not include these parts and accessories.

2. Sample size used for the test set and the data provenance

Not applicable. Clinical performance testing was not performed. The testing conducted was primarily engineering and bench testing against recognized standards.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. Ground truth as typically understood for clinical studies (e.g., expert interpretation of medical images) was not established. Performance was assessed against engineering specifications and international standards by relevant testing laboratories.

4. Adjudication method for the test set

Not applicable. No expert review or adjudication method was described as clinical performance testing was not performed.

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. No MRMC study was conducted as this device is an Integral Dental Unit, not an AI-assisted diagnostic or therapeutic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This device is not an algorithm or AI system.

7. The type of ground truth used

The "ground truth" for this device's performance is based on conformance to international engineering and safety standards (e.g., IEC, ISO) and the device's adherence to its own design specifications and functional parameters. There is no clinical "ground truth" derived from patient outcomes or expert consensus in this submission.
