The prophylaxis treatments are obtained by the projection of water, air and appropriate dental prophylaxis powders, onto the treatment site. PROPHYflex 4 Handpiece and Accessories in supra-gingival configuration is intended for use in the cleaning and polishing of teeth by removal soft deposits and areas of discoloration as well as preparing teeth for fillings or veneers and cleaning fixed bands and brackets on orthodontic appliances. PROPHYflex 4 Handpiece and Accessories in subgingival configuration is indicated for the non-surgical removal of subgingival plaque in pockets up to 5 mm after initial periodontal treatment.
Device Description
The PROPHYflex 4 is an air polishing device/powder jet handpiece that projects a mixture of water and air with sodium bicarbonate, calcium carbonate or fine glycine power onto tooth surfaces. The device includes the handpiece main body with adjustable spray feature, two cannulas, a wrench for installing the cannula, two interchangeable gripping sleeves, powder container with cover, a cleaning burr and nozzle pin, and a set of spare o-rings. An optional adapter and perio tip can be installed for subgingival treatments. The powder is filled into the powder container by the user. When activated through foot control, air is pushed into the powder container, swirling the powder and pushing it through the device and out of the cannula. The spray is only mixed with the air and powder at the very tip of the cannula, providing an even and gentle cleaning effect. The amount of powder can be regulated via three different spray settings by the adjusting ring, helping the users to perform individual treatments such as subgingival biofilm removal, removal of discoloration and bacterial plaque, orthodontics, cleaning prior to fissure sealing, prosthetics, conservative and aesthetic dentistry by providing the possibility to adjust the cleaning effects to the clinical situation of the patient at hand. The components of the PROPHYflex 4, including the powder container, is to be completely reprocessed after each use. The three powder levels are as follows: - Highest Level: Suitable for supragingival treatment and offers full cleaning power . - Medium Level: Suitable for sub- and supragingival treatment and enables . gentle cleaning at a reduced powder quantity - . Lowest Level: Helps rinsing the powder off the tooth and blowing the powder from the system after the treatment During supraqinqival treatments (e.g. stain removal), the device doesn't touch the patient but will be placed 3 – 5 mm from the area that is to be cleaned. During subgingival treatments (biofilm management) with the perio tip, the tip is inserted into the pocket up to 5mm and angled towards the tooth.
More Information

No
The device description and performance studies focus on mechanical and material properties, with no mention of AI or ML. The "adjustable spray feature" is a manual setting, not an intelligent system.

Yes
The device is intended for prophylaxis treatments, including cleaning and polishing teeth, removing deposits, and non-surgical removal of subgingival plaque, which are therapeutic medical interventions.

No

The device is described as an air polishing device/powder jet handpiece intended for prophylaxis treatments, including cleaning and polishing teeth and removing subgingival plaque. Its function is to perform a physical treatment (cleaning/polishing/removing plaque) rather than to diagnose a condition or disease.

No

The device description clearly outlines a physical handpiece with various accessories (cannulas, wrench, gripping sleeves, powder container, etc.) that projects a mixture of water, air, and powder. This is a hardware device, not software only.

Based on the provided information, the PROPHYflex 4 Handpiece and Accessories is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • PROPHYflex 4 Function: The PROPHYflex 4 is a dental handpiece that performs prophylaxis treatments by projecting a mixture of water, air, and powder onto the teeth and into subgingival pockets. It is a therapeutic and cleaning device used directly on the patient's body.
  • Lack of Specimen Analysis: The device does not analyze any biological specimens to provide diagnostic information. Its function is purely mechanical/physical cleaning and polishing.

Therefore, the PROPHYflex 4 Handpiece and Accessories falls under the category of a medical device used for treatment and cleaning, not an In Vitro Diagnostic device.

Principle of Operation / Mechanism of Action:

PROPHYflex 4 connects to a dental treatment unit's tubing via KaVo MULTIflex coupler or a Sirona coupler that supplies air and water to the handpiece separately. The air is redirected through the PROPHYflex 4 main body to the powder container. The powder container – holding the sodium bicarbonate or calcium carbonate or glycine powder – is filled according to the treatment indication. The air draws the powder from the container to the cannula in the front of the handpiece. There, the powder is mixed with water that has been transported from the dental treatment unit coupling system to the tip of the cannula focuses this air, water and powder mixture into a stream. The air and water can be adjusted at the dental treatment unit or via the treatment unit foot control. The powder can be adjusted to 3 different levels using the adjustable ring at the base of the PROPHYflex 4 handpiece.

5. Indications for Use:

Dear Frank Ray:

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

12

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/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); 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).
