TORQTECH transmits rotation of the motor to dental burrs and reamers which cut or grind teeth or dentures with the same or transformed rotation.
The TORQTECH device is a dental handpiece to be attached to an electric or air powered dental motor, designed for polishing, grinding, and drilling of teeth/dentures. The device transmits rotational force from the motor to the rotor shaft through a clutch, and the dental burrs or reamers chucked on the shaft are able to polish, grind or cut the teeth/dentures of the patient receiving these rotations. There are two types of the TORQTECH device: one is a "straight" linear model (Model ST-DH) while the other is angled and geared (Models CA-DC, CA-DC-O, and CA-5IF-O). The geared models vary based on angle and rotation due to the gear between the clutch and rotor shaft. An optional headlight is available, fed through the light-guide from the motor portion.
Here's an analysis of the provided text regarding the TORQTECH device's acceptance criteria and the study proving it, structured according to your request:

2. Sample Size Used for the Test Set and Data Provenance
The provided summary does not mention a "test set" in the context of a clinical study or a specific dataset used for performance evaluation of the device against a ground truth. The primary method for proving the device meets acceptance criteria appears to be adherence to recognized standards and a substantial equivalence comparison to predicate devices, rather than a direct performance test against a separate "test set" as one might find in software or diagnostic device submissions.
The provenance of data is not applicable in the sense of patient data as no clinical tests were performed.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. No "test set" with ground truth established by experts is described in the document. The evaluation relies on compliance with technical standards and comparison to predicate devices.
4. Adjudication Method for the Test Set
Not applicable. No "test set" requiring adjudication 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 a dental handpiece, not an AI or diagnostic imaging device. Therefore, no MRMC study or AI assistance evaluation was conducted.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
Not applicable. This device is a manual dental instrument, not an algorithm.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for this device's acceptance is primarily established by:
- Compliance with recognized international standards (ISO, EN).
- Demonstrated substantial equivalence to legally marketed predicate devices, implying that if the device is similar in technology, intended use, and performance characteristics to a device already deemed safe and effective, it is also safe and effective.
- Results of specific non-clinical tests (sensitization, irritation, cytotoxicity) against relevant ISO standards.
8. The Sample Size for the Training Set
Not applicable. This device is a hardware dental handpiece, not a machine learning model. Therefore, there is no "training set" in the AI sense.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.

6. DEVICE DESCRIPTION/SUBSTANTIAL EQUIVALENCE
DEVICE DESCRIPTION
The TORQTECH device is a dental handpiece to be attached to an electric or air powered dental motor, designed for polishing, grinding, and drilling of teeth/dentures. The device transmits rotational force from the motor to the rotor shaft through a clutch, and the dental burrs or reamers chucked on the shaft are able to polish, grind or cut the teeth/dentures of the patient receiving these rotations.
There are two types of the TORQTECH device: one is a "straight" linear model (Model ST-DH) while the other is angled and geared (Models CA-DC, CA-DC-O, and CA-5IF-O). The geared models vary based on angle and rotation due to the gear between the clutch and rotor shaft. An optional headlight is available, fed through the light-guide from the motor portion.
SUBSTANTIAL EQUIVALENCE
The TORQTECH and its predicate devices have similar general intended uses, similar principles of operation, and similar technological characteristics. Although there are minor differences in the characteristics of the TORQTECH and its predicate devices, these differences do not raise new questions of safety or. effectiveness.
The TORQTECH is substantially equivalent to the following devices:
(1) Kaltenbach & Voight GmbH's "INTRAmatic," "INTRAcompact," and "GENTLEpower" (K#080677) for purposes of performance characteristics; and
(2) J. Morita Manufacturing Corp.'s own "Twinpower Turbine" handpiece (K#061701) for purposes of biocompatibility of materials
(3) J. Morita Manufacturing Corp.'s own "AR Spray" (included as part of K#070074) and KAVO "KavoQuattrocare" spray (K#012308) for purposes of the LS Spray that is included with the TORQTECH device.
Two charts identifying the specific characteristics of these various devices appear below:

7. INDICATIONS FOR USE
TOROTECH transmits rotation of the motor to dental burrs and reamers which cut or grind teeth or dentures with the same or transformed rotation
8. SUMMARY OF NON-CLINICAL TESTING
The TOROTECH was developed and tested in accordance with the following standards:
ISO 7785-2:1995 (dental handpieces - Part 2: straight and geared angle handpieces)
ISO 3964 (dental handpieces - coupling dimensions)
ISO 14971:2007 (medical devices - application of risk management to medical devices)
ISO 10993-1:2203 (biological evaluation of medical devices -- Part 1: evaluation and testing)
ISO 10993-5:2009 (biological evaluation: test for in vitro cytotoxicity)
ISO 10993-12:2007 (biological evaluation: sample preparation and reference materials)
ISO 17664:2004 (information to be provided by the manufacturer for the processing of resterilizable medical devices)
EN 980:2008 (graphical symbols for use in the labeling of medical devices)
EN 1041:2008 (information supplied by the manufacturer with medical devices)
The spray used with the TORQTECH device is considered a mucosal contacting substance of less than 24 hour duration under Annex A of ISO 10993-1: 2009. Results of sensitization and irritation testing under ISO 10993-1 showed the spray to not cause sensitization and that it is not an irritant. The cytotoxicity test results under ISO 10993-1, combined with risk analysis under ISO 14971:2007, demonstrate that the spray is suitable for the clinical application. Finally, with respect to the propellants in the spray, the same gases have been cleared for use in the Kavo predicate device K#012308.
{4}------------------------------------------------
9. SUMMARY OF CLINICAL TESTING
No clinical tests were performed for the TORQTECH device.
10. CONCLUSION
The information above demonstrates that the TORQTECH device is substantially equivalent to the predicate devices.
