Intended Use

tün® ultrasonic tips are intended for use by dental professionals for the removal of soft and hard tissue during endodonic root canal preparation procedures. They can also aid in the removal of endodontic posts and other intra-canal blockages.

Device Story

tün® ultrasonic tips are stainless steel accessories for piezoelectric ultrasonic handpieces/scaler units; used by dentists, endodontists, oral surgeons, and dental hygienists in dental clinics. Tips vibrate at 20,000–35,000 Hz to remove soft/hard tissue, endodontic posts, and intra-canal blockages during root canal procedures. Device consists of 6 tip variants (some with diamond/zirconium nitride coating) manufactured via sintering. Healthcare providers attach tips to ultrasonic units; output is mechanical vibration for tissue/obstruction removal. Benefits include improved access and efficiency in endodontic procedures. Device is non-sterile and requires cleaning/steam sterilization before use.

Clinical Evidence

Bench testing only. No clinical data provided. Biocompatibility testing performed per ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation/sensitization). Packaging/shipping validated per ISTA 3A.

Technological Characteristics

Material: 17-4PH stainless steel (UNS S17400). Sensing/Actuation: Piezoelectric ultrasonic vibration (20,000–35,000 Hz). Form factor: 6 tip designs with M3x0.5 or M3x0.6 threads. Coatings: Nickel or Diamond Nickel. Sterilization: Steam autoclave. Connectivity: Mechanical interface to third-party ultrasonic handpieces.

Indications for Use

Indicated for dental professionals performing endodontic root canal preparation, including removal of soft/hard tissue, endodontic posts, and intra-canal blockages.

Regulatory Classification

Dear John Ziobro:

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.

- 10. Proposed Indication for Use:
tün® ultrasonic tips are intended for use by dental professionals for the removal of soft and hard tissue during endodontic root canal preparation procedures. They can also aid in the removal of endodontic posts and other intra-canal blockages.

- 11. Compliance to Special Controls / Performance Standards: Compliance to the following recognized consensus standards is declared:
- ISO 7405 Second edition 2008-12-15 Dentistry Evaluation of biocompatibility of medical devices used in dentistry [Including: Amendment 1 (2013)]. The application of this standard resulting in testing to:
- ISO 10993-5:2009 / (R) 2014 Biological Evaluation of Medical Devices-Part 5: Tests for in vitro cytotoxicity
- ISO 10993-10:2009 / (R) 2014 Biological Evaluation of Medical Devices-Part 10: Tests for irritation and skin sensitization
- ISTA 3A General Simulation Performance Test Procedure: Packaged- Products for Parcel Delivery System Shipment 150lbs or less
- 12. Technological Characteristics

The proposed device is similar to the predicate device and as substantially equivalent technological characteristics.

- 13. Comparison to Predicates
The main differences between the tün® ultrasonic tips under review and the predicate device cleared under K132609 are as follows:

- The proposed device is plated while the predicate device is not. This difference is a function of the manufacturing method and does not affect the overall safety or performance of the device. Note: The predicate device chosen by EDS that cleared under K960889 used Titanium Nitride as plating materials.
- The proposed device is manufactured by sintering while the predicate device is machined. The end result ● from either method are ultrasonic tips with similar geometries and identical intended uses. The different manufacturing methods simply reflect the in-house equipment / manufacturing capabilities of the two different companies and do not affect the overall safety or performance of the device.
- . The proposed device uses a Chromium:Nickel:Copper stainless steel alloy, while the predicate device uses a Chromium:Nickel:Molybdenum stainless steel. The materials were chosen based on the manufacturing methods and do not affect the overall safety or performance of the device.
- The proposed device offers 6 variants; the predicate device offers 6 variants, but there isn't an exact 1:1 matchup and the overall sizes and weights are slightly different. However, these differences do not raise any new questions of safety or effectiveness.

The minor differences between the ultrasonic tips under review and the predicate device cleared under K132609 are as follows:

- The proposed device consistently references the ISO standard for thread sizes to interface with the ultrasonic ● generators (M3x0.5 or M3x0.6 thread), while the predicate device references one ISO and one American standard (M3x0.5 and #5-40 thread).
- The proposed device explicitly states the intended users, the intended use environment, the targeted patient . population, the operating & storage temperatures, compliance to specific standards, etc. while the predicate device does not.

The proposed device states that they are to be "used on piezo ultrasonic endodontic and scaler units which operate in the range of 20,000hz - 35,000hz," while the predicate device states that they vibrate "at high frequencies (up to 40,000 Hz)."

A table showing substantial equivalence to the predicate device follows:

| Catalog Numbering | The catalog number schema uniquely identifies each<br>variant as tun-e-X or tun-e-Xe<br>Where e-X = Satelec type threads and X = the tip style<br>from 1 to 6<br>And e-Xe = EMS type threads and X = the tip style from<br>1 to 6. | The catalog number schema uniquely identifies each<br>variant as 610-XX or 615-XX<br>Where 610 = E type threads; 615 = M type threads<br>And XX = the tip style from 01 to 06.<br>Image: 610-xx E-Threads Fit These Units:<br>Image: 615-xx M-Threads Fit These Units: | Both the proposed and predicate devices offer a total<br>series of 6 tips that use two different thread styles for<br>a total of 12 different tips. The proposed devices call<br>M3x0.6 threads "Satelec" style, while the predicate<br>calls them "E" style and proposed devices calls<br>M3x0.5 threads "E" style, while the predicate calls<br>them "M" style. Both devices use a formulaic catalog<br>numbering system to encode for the 12 variants.<br>Although the systems are different, no new issues of<br>safety or effectiveness are introduced.<br>Therefore, Substantially Equivalent |
