# 4. Identification of Predicate Device(s) [21 CFR 807.92(a)(3)]

The identified predicate devices within this submission are shown as follows:

- . 510(k) Number: K123582
●

Applicant:

- Saeyang Microtech Co., Ltd.
- Common Name: Dental Handpieces ●
- . Device Name: Endo a class
- . 510(k) Number: K111616
- Applicant: Saeshin Precision Co., Ltd
- Dental Handpieces Common Name: ●
- Device Name: E-CUBE

K123582 is the primary predicate and K111616 is the reference predicate. There are no significant differences between the TRAUS ENDO dental handpieces and the predicate devices that would adversely affect the use of the product. It is substantially equivalent to these devices in device design, composition of materials and technical specifications.

#### 5. Description of the Device [21 CFR 807.92(a)(4)]

The TRAUS ENDO is an AC-powered device that includes a power unit, charging station and contra-angle handpieces, ACL(B)-41EP, ACL(B)-42EP and ACL(B)-45EP, are grinding, cutting, and polishing work in dental oral use.

#### Intended Use [21 CFR 807.92(a)(5)] 6.

The TRAUS ENDO, ACL(B)-41EP, ACL(B)-42EP, and ACL(B)-45EP, are indicated for use by dentists in standard endodontic procedures using rotary files and rotary endodontic drills (Gates-Glidden).

# 7. Technological Characteristics [21 CFR 807.92(a)(6)]

- Model Nos. ACL(B)-41EP, ACL(B)-42EP and ACL(B)-45EP ●
- Gear Ratio: 20:1, 16:1, 32:1
- Dimensions: Ø 16.7 X 63 mm, Ø 16.7 X 63 mm and Ø 16.7 X 63 mm .
- Weight: 34.8 g
- Charger: AC 100 - 240 V, 50 /60 Hz, DC 4.5V

One difference noted between the TRAUS ENDO and its predicates is its slower rotational speed, as a result of the 32:1 gear reduction ratio. However, equivalence to predicates has been demonstrated through bench testing and this difference raises no new concerns.
