With the best recommendations

The PROPHYflex 4 has excelled in my daily work – it fits perfectly in the hand and can be individually configured through the two grip sleeve lengths. The spray mist can also be easily controlled, which is something my patients like as well.
Tanja Wicharz
Prophylaxis expert and practice instructor, Germany
After each application and before each reprocessing, run the PROPHYflex 4 connected to the turbine coupling with water for one minute and then without water. This lets you ensure that no powder residue is left in your PROPHYflex 4 that could block it. You can also blow out remaining powder residue in the PROPHYflex 4 handpiece using the first level of the three-level adjustment. After subsequent cleaning and reprocessing, it’s ready to use for the next treatment.

In which cases do I need to remove the nozzle in the back?

The nozzle does not necessarily need to be changed. Unlike the PROPHYflex 3, there is only one nozzle available. This nozzle does not have to be removed for use or reprocessing. In case of heavy clogging, the nozzle can be unscrewed using the rear of the key for the cannula. Afterwards, the powder tube can be cleaned from both sides with the cleaning burr.

Why is the powder stream not removing anything when on the lowest cleaning setting?

The lowest power setting is almost powderless. It only pushes the leftover powder out of the handpiece. Therefore, this setting is not meant for the removal of discoloration. This setting can be used to rinse leftover powder off the tooth. It also helps prevent clogging when rinsing the powder out of the handpiece after the use. 

I always work with fine powders with low abrasion effects. Why do I get the feeling that the new PROPHYflex has less cleaning abilities?

With conventional cannula systems, the powder stream is wider although its highest cleaning abilities is in the center of the stream. With the PROPHYflex 4 cannula system, the stream is narrower, more homogeneous and gentler. This makes the new cannula system less abrasive. If the abrasion is not high enough we advise to check the power settings. With the new cannula system, powders with higher abrasiveness can also be used, as even they become gentler.

Why do I need to put the reprocessing seal on the handpiece for proper reprocessing?

The reprocessing seal redirects the cleaning media to the powder tube. Therefore, the seal must be placed on the handpiece to make sure that the powder tube is also properly reprocessed during mechanical reprocessing.

Can I reprocess the cannula and the holding part together?

It is possible to reprocess the complete front part of the PROPHYflex 4 (cannula and holding part). This process has been validated and therefore is an option. However, if there is a risk of there being a contaminated thread on the cannula (e.g. if the cannula has been screwed/unscrewed during the treatment), the parts need to be reprocessed separately.

Can I reuse powder if I seal the powder container with the cap?

No, the cap is meant to help with the preparation of the powders before the treatment. This way, different powders can be prepared and the treatment can be flexibly carried out according to the patient’s needs. The powder should not be reused because there is a risk of cross contamination.

The perio tips from my Perio Kit have been reprocessed 10 times now. How do I refill my kit?

A dedicated set is available to refill the Perio Kit. The Refill PROPHYflex perio tip (1.010.0287) contains 10 perio tips and can be used to refill the PROPHYflex 4 Perio Kits (1.011.9403) as well as the PROPHYflex Perio Kit (1.009.3731) used for the PROPHYflex 2 and 3.

Can I use powders from other manufacturers with the PROPHYflex 4?

It is not possible to use non-KaVo powders with the PROPHYflex 4.

When do KaVo powders expire?

The expiry information can be found on sticks, bottles and outer packaging, with the claim „Use by x years“.

  • PROPHYflex Powder: 5 years
  • PROPHYpearls neutral: 5 years
  • PROPHYpearls flavors: 3 years
  • PROPHYflex Perio Powder: 2 years
