#### 7. Performance Data(Non-Clinical):

The following properties were tested based on the referenced standards. All the test results support substantial equivalence to the predicate devices.

- Performance test in accordance with ISO 14457:2012 Dentistry Handpieces and motors
- . Sterilization validation testing in accordance with ANSVAAMI ST79, ISO17665-1, ISO 17665-2, ISO 11138-1, and ISO11138-3
- · Electrical safety and EMC test in accordance with IEC 60601-1, IEC 60601-1-6, EN 606011-1-2, EN 61000-3-2, EN 61000-3-3

#### Performance Data(Clinical): 8.

No clinical performance testing was provided in the submission.

#### 9. Substantial Equivalence

MEG-TORQ is substantially equivalent to ISD900 (K110278). The following comparison table is presented to demonstrate substantial equivalence.

The intended use of the subject device is the same as the predicate device. The subject device is also similar to the predicate device in terms of operational modes, type of chuck, patient contacting part, and shank type which confirms to ISO1797-1. The differences between the subject device and the predicate devices are device dimensions, speed in rpm, and torque options. However, the non-clinical performance test results provided in this submission support that the subject device is substantially equivalent to the predicate device. Especially, the maximum speed and torque test was performed to verify that the use of the subject device with the highest rpm does not shear off the abutment screw. The test results showed that this difference does not raise a concern in this regard.
