Device Description
The STRONG Dental Handpieces; ACL(B)-03C and ACL(B)-03F are gear driven handheld dental handpieces with Gear Ratio of 1:1. They can be driven by torque adjustable electrical motors for surgery treatment. They are attached to drive via ISO 3964 coupling. The head clamp accepts instrument complying with ISO 1797-1. They have contra-angle attachment for difficult to reach areas intended to prepare dental cavities for restorations, such as fillings, and for cleaning teeth.
More Information

Not Found

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

Yes
The device is described as being used for various dental procedures such as implant placement, periodontal surgeries, bone grafting, and removal/sectioning of teeth, all of which are considered therapeutic interventions.

No

Explanation: The device description and intended use clearly indicate that the STRONG Dental Handpieces are used for various dental procedures such as implant placement, bone contouring, and removal of teeth, which are all treatment-oriented actions, not diagnostic ones. There is no mention of the device being used to identify or analyze medical conditions.

No

The device description clearly states it is a "gear driven handheld dental handpiece" and describes physical components and performance characteristics related to hardware (extraction force, eccentricity, temperature rise, resistance to sterilization). There is no mention of software as the primary or sole component.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Description and Intended Use: The description and intended use of the STRONG Dental Handpieces clearly indicate they are used for surgical procedures directly on the patient's body (implant placement, periodontal surgeries, bone grafting, tooth removal). They are mechanical tools for manipulating tissue.
  • Lack of Specimen Analysis: There is no mention of the device being used to analyze any biological specimens.

Therefore, based on the provided information, the STRONG Dental Handpieces are not IVD devices. They are surgical instruments.
