No
The device description and performance studies focus on mechanical and optical properties of a dental handpiece, with no mention of AI or ML.

No
The device is a dental abrasive tool used for preparing teeth, not for treating or curing a disease or condition.

No

The device is described as an abrasive tool used for material removal and preparation, not for identifying pathologies or conditions.

No

The device description clearly details a physical, mechanical device (dental handpiece) with various hardware components (air turbine, cooling system, head types, optic light guide, coupling). It is not solely software.

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

Here's why:

  • Intended Use: The intended use clearly describes a device used for mechanical procedures on teeth (removing material, preparing cavities, polishing, etc.). This is a direct intervention on the patient's anatomy.
  • Device Description: The description details a high-speed rotating dental tool. This is a physical instrument used in a dental procedure.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body to provide information for diagnostic purposes. IVDs typically involve analyzing blood, urine, tissue, or other bodily fluids or samples.

This device is a dental instrument used for treatment and preparation, not for in vitro diagnostic testing.

Device Description

The proposed devices, High Speed Air Turbine Handpiece, is a dental abrasive device that rotates at high speed air as the driving force. It has 11 models: G100, G200, G300, G400, G450, G500, G600, G700, G700L, G800 and G800L.
The proposed device has the following features
The cooling system includes air/water spray or only water spray. .
The head types include standard head and miniature head.
The angle of the head and shaft include 45℃ and 90°. In general, dentist usually uses 90° handpiece having teeth treatment. Except for wisdom teeth 45°handpieces is considered more desirable for wisdom teeth operation .It is because the 45° angle is more appropriate for the angle of eruption of wisdom teeth.
High Speed Handpieces are able to run from 320,000rmp to 430,000rmp. G450, G700L and G800L have optic light guide for light function, other models don't have the optic light guide. Coupling is the accessory for the some models of the proposed handpiece to connect with tubes of dental unit. G500 and G600 require additional 4-hole coupling, and the 4-hole coupling is included in the product package. G450,G700, G800 and G800. require additional quick coupling is not included in the product package. The user shall purchase the compatible coupler for G450,G700, G700L, G800 and G800L.
