Intended Use

The Impla-NX (Model: ISE-270M) is intended for use in dental oral surgery and dental implant. The main unit is designed to be used with a specific dental micromotor that drives dental handpieces fitted with appropriate tools to cut hard tissues in the mouth.

Device Story

Impla-NX (Model: ISE-270M) is an implant surgical engine for dental surgery. System components include a main control unit, BLDC motor, and foot control. Device operates by converting AC power to DC to drive the BLDC motor, which provides rotational power to connected dental handpieces. Used in clinical dental settings by professionals to perform oral surgery and implant procedures. Output is rotational mechanical energy for cutting hard tissues. Healthcare providers control parameters (speed, torque) via the unit; device assists in precise surgical site preparation. Benefits include controlled, motorized tissue cutting for dental implants.

Clinical Evidence

No clinical data. Bench testing only. Testing included ISO 3964 (coupling dimensions), ISO 7494-1 (dental units), ISO 14457:2017 (handpieces/motors), ISO 17665-1/2 (steam sterilization), IEC 60601-1/1-2 (electrical safety/EMC), IEC 80601-2-60 (dental equipment safety), and IEC 62471 (photobiological safety).

Technological Characteristics

System includes control unit, BLDC motor, and wired foot switch. Operates on AC power converted to DC. Features include adjustable speed (200-40,000 rpm) and torque (max 70Ncm). Connectivity is via wired handpiece/foot control. Sterilization validation per ISO 17665-1, 2. Complies with IEC 60601-1, IEC 60601-1-2, and IEC 80601-2-60.

Indications for Use

Indicated for dental oral surgery and dental implant procedures requiring the cutting of hard tissues in the mouth.

Regulatory Classification

Identification

Dear Priscilla Chung:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

{1}------------------------------------------------

statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

### 8. Indications for Use

The Impla-NX (Model: ISE-270M) is intended for use in dental oral surgery and dental implant. The main unit is designed to be used with a specific dental micromotor that drives dental handpieces fitted with appropriate tools to cut hard tissues in the mouth.

#### 9. Substantial Equivalence Discussion:

The Impla-NX (Model: ISE-270M) is substantially equivalent to Surgic pro( K173905) in the indications for use and the technological characteristics. The following comparison table is presented to demonstrate substantial equivalence.

The Impla-NX (Model: ISE-270M) does not have new Indications for Use: it is the same as the predicate device's indications for use. It shows equivalent specifications with the predicate devices in most of parameters.

The difference between the subject device and the predicate device is the number of memory set but this does not affect the performance as it is just for user convenience. The user can always adjust the setting parameters as needed.

Another difference is the torque of motor that the subject device has a slightly lower max torque than the predicate device. However, the max torque of 70Ncm is more than enough to be used in the clinical setting for the Indications for Use and it is covered by the max value of the predicate device; therefore, it would not raise a question in safety.

We conclude that the subject device is substantially equivalent to the predicate device.
