It connects to a standard dental unit turbine hose (Midwest 4-hole or KaVo MULTIflex) which supplies compressed air and water. Compressed air acts as the energy source, driving an internal vibrator to generate subsonic mechanical vibrations (2000-3000 Hz) transmitted to an attached endodontic file. Water is supplied for cooling and cleaning the treatment site. The device is supplied non-sterile and requires steam autoclave sterilization by the user between patients. By utilizing mechanical and abrasive action, the device removes dentine debris from root canals, facilitating endodontic treatment. ## Clinical Evidence No clinical data. Bench testing only, including frequency output, amplitude, resistance to autoclave sterilization, and corrosion testing in accordance with ISO 18397:2016 and ISO 9168:2009. ## Technological Characteristics Air-driven dental handpiece; materials include stainless steel, aluminum alloy, silicone rubber, and fluoro-rubber. Operates via compressed air (0.28 MPa) to generate subsonic vibrations (2000-3000 Hz). Connects to dental unit via 4-hole or quick-disconnect coupling. Sterilization via steam autoclave. Mechanical device; no software or electronic algorithms. ## Regulatory Identification An ultrasonic scaler is a device intended for use during dental cleaning and periodontal (gum) therapy to remove calculus deposits from teeth by application of an ultrasonic vibrating scaler tip to the teeth. ## Predicate Devices - Sonic Air MM1500+ (MID) ([K081268](/device/K081268.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Sonic Air MM1500+ (MID), K081268 #### DESCRIPTION OF DEVICE The prosed device is used by dental professionals for removal of dentine debris in root canals in the field of endodontics. A turbine hose from a dental unit that supplies the device with compressed air and water is attached of the device in order to use the device. The compressed air is the energy source of the device to generate mechanical vibration. Water from the dental unit is used for cooling and cleaning the treatment site. The device consists of the handpiece including the connection to a hose and file holder. The proposed device has two model 4H connects to the Midwest 4-hole turbine hose and the model K A connects to the KaVo MULTIflex® quick-disconnect coupling. The associated accessories include: - file holder to attach endodontics files - replacement wrench for the holder {4}------------------------------------------------ The proposed device and accessories are supplied non-sterile and must be sterilized in an autoclave prior to the first use and after every patient by the end-user. #### TECHNOLOGICAL CHARACTERISTICS When compressed air enters inside of the vibrator in the device, vibration generates and is transmitted to an endodontic file attached to the device. Dental treatment with the devices is performed by use of the vibration. #### COMPARISON OF TECHNOLOGY #### * Similarities: The proposed and predicate devices use compressed air supplied from a dental unit as energy source. The both devices have very similar design: handpiece with a connection at the rear end to hose of a dental unit and a file holder or head to accept the specific instruments (endodontic files). Their operation principle is same. When compressed air enters inside of the vibrator in the device, vibration generates and is transmitted to an endodontic file attached to the device. Dental treatment with the devices is performed by use of the vibration. Both the proposed and predicate device are supplied non-sterile and require sterilization by the user. #### * Differences: The proposed device use a difference working air pressure and air consumption volume from the predicate device. The working air pressure is to gain the desired performance of endodontic treatment, and the air consumption volume is influenced by the working air pressure. The output frequency of the proposed device is based on the actual measured values from the performance testing. No breakage of the endodontic files occurred in the performance testing when operated at the specified air pressure. Thus the submitter believes these points does not raise concerns about safety and effectiveness. Performance testing of frequency output and amplitude was conducted at the air pressure of 0.28 MPa and passed the acceptance criteria of the applicable standard ISO 18397:2016 (see "NON-CLINICAL PERFORMANCE TESTING" below). | | K171150 | K081268 | |--------------------------|-------------------------------------------------------------------------------------------------|--------------------------------------------------------| | Product name | AW-100 | Sonic Air MM1500+ (MID) | | 510(k) number | K171150/S001 | K081268 | | Manufacturer / submitter | Micron Corporation | Micro Mega S.A. | | Indications for use | The device is intended to be used for

head to accept the specific instruments (endodontic files). | | | Operation principle | The both devices are air-driven handpieces transmitting sonic waves along an
endodontic file, which generates when compressed air enters inside of the
vibrator in the device. The handpiece produces subsonic vibrations.
The cutting action is produced by mechanical and physical movement on the
root canal (abrasive action) the handpieces remove dentine debris. | | | Performance | Output frequency 2000 to 3000 Hz. | Output frequency 1500 to 3000 Hz. | | Working air pressure | 0.28 MPa (40.6 psi, 2.8 bar, 2.86 kgf/cm²) | 2.2 to 2.5 bar (31.9 to 36.2 psi) | | Air consumption volume | 0 - 26 l/min | 18 -25 l/min | | Water flow volume | 56 ml/min. (at water pressure 0.2 MPa). | Not available. | | Weight | 71g (model 4H) or 72g (model KA) | Not available. | | Material used | Stainless steel, aluminum alloy,
silicone rubber and fluoro-rubber | Not available but metal and rubber
materials that can withstand steam
autoclave sterilization are used. | | Components | Handpiece and file holder or head to accept the specific instruments
(endodontic files). | | | Sterile or non-sterile | Supplied non-sterile. | | | Sterilization | Steam autoclave | | At a high level, the proposed and predicate devices are based on the same technological characteristics as above. There are some small different technological characters between the proposed device and the predicate including working air pressure, air consumption volume or the range of output frequency as in the chart above. However, the working air pressure of 0.28 MPa is for the desired performance at the same level as the predicate device and this working air pressure accompanies the air consumption volume of 26/min. The output frequency is based on the actual values measured in the performance testing. Bench performance testing was conducted at the working air pressure of 0.28 MPa and in this testing, no breakage of the endodontic files occurred. #### NON-CLINICAL PERFORMANCE TESTING The proposed device was evaluated in accordance with elements of applicable international standards for medical devices in which the proposed device is categorized (dental powered scaler). Performance tests included evaluation of basic safety and performance requirements, risk management, biocompatibility testing, and reprocessing validation. The device passed all of the compliance tests. Bench performance testing, including frequency output, amplitude, resistance to autoclave sterilization and corrosion was conducted in accordance with the following standards: ISO 9168:2009, Dentistry -- Hose connectors for air driven dental handpieces, ISO 18397:2016, Dentistry -- Powered scaler {6}------------------------------------------------ The device passed all of the performance criteria. ## CLINICAL PERFORMANCE TESTING Clinical performance testing was not conducted. ## CONCLUSIONS Based on the same intended use, principle of operation, comparison of technology and results of non-clinical performance testing, we conclude that AW-100 is substantially equivalent to Sonic Air MM1500+ (MID), K081268. --- **Source:** [https://fda-staging.innolitics.com/device/K171150](https://fda-staging.innolitics.com/device/K171150) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
