    Your question – our answer & FAQ

    • Please see the video of Christian Lechner about your question "How do I ensure safety in my practice?"
      Christian Lechner is responsible for the application segment of reprocessing and infection control at W&H. We are daily receiving inquiries from dentists all over the world, on how to protect themselves, their staff and their patients from infections, especially during Covid-19.

      1. What is a proper disinfectant?
      Important, when choosing a ready to use disinfectant, is primarily the microbiological efficacy in combination with the contact time. Please read the instructions for use of the manufacturer carefully. Some local institutions are offering free information on this topic. As an example for Germany you can consult the free accessible VAH list, for the US there is an official information available on the FDA website.

      2. How to clean and reprocess your instruments properly?
      Sterilization, hygiene and maintenance are increasingly important in the dental practice!
      W&H offers a complete and flexible workflow solution for your instruments. Hygiene guidelines and recommendations differ from country to country – we would like to give a best practice example
      P.S. W&H offers a wide range of accessories for optimizing of the sterilization process. Minor extras lead to major results. Work in the practice is easier and your team saves time.

      3. What are the advantages of a B-class sterilizer?
      Did you know, that you can save valuable time by using our B- class sterilizers with eco-dry technology? Find out more about the new LISA.

      4. Why should you use a thermal washer disinfector in your dental practice?
      The new Teon is a highly efficient thermal washer disinfector. Thanks to its dedicated programs it offers the best cleaning and disinfection for your dental practice. Teon improves the job organization of your hygiene room, reduces the reprocessing time and increases the protection against cross contamination.
    • Tobias Schwarz is responsible for the product portfolio restorative dentistry at W&H. Since there is more common awareness about the role of aerosols in infection transmission we are receiving many questions. Whats the right highspeed handpiece to be used to reduce the formation of aerosols? And many more...

      Do air turbine handpieces produce more aerosol than electric highspeed handpieces?
      The amount of water spray, coming from both kind of handpieces, is basically the same. The essential difference is the bur speed, that would have different acceleration effects on the water drops once they hit the bur as well as different air velocity at the area around the bur. Turbine handpieces are running approximately 400.000 rpm. Electric highspeed handpieces are operated at 200.000 rpm, so half the speed as turbines. As a matter of fact, the intensity how particles are distributed is less. This has a beneficial effect on limiting the exposure of water spray generated aerosol into the dental operatory environment. Additional air, leaking at the turbines head – caused by the drive air to run the turbine - increases the distribution radius of floating particles around the air turbine handpieces head. This effect is significantly less with electric highspeed handpieces as well. Nevertheless, W&H Turbine handpieces are known to have noticeable less air leakage at the turbine head then the average product on the market.

      Do air turbine handpieces produce more aerosol than electric highspeed handpieces?
      What’s the purpose of the water spray at dental highspeed handpieces?
      Highspeed preparation procedures require proper cooling at the contact area between the rotating instrument and the tooth. Especially the heat, generated during gross reduction of tooth structure, would cause significant thermal damage to vital teeth.
      That’s why dental highspeed handpieces are equipped with an ideally multi-directional water spray system with 3, 4 or 5 ports directed to the burs tip. Positive side effect is, that the cutting ability of rotating instruments is supported as the water spray does cleans out debris at the cutting part of the bur.

      What’s the purpose of the water spray at dental highspeed handpieces?
      How does the water spray affect the formation of potentially harmful aerosol?
      The water spray itself, as it comes from the handpiece, is not a risk at all for infections if the water quality is ensured with the dental delivery system. Only, when the water drop got contact with the patient, it could have absorbed potentially germs which then subsequently rebounds from any surface within the oral cavity and spreads as infectious aerosol.

      Why can’t I just turn off the air used for the spray to reduce the formation of aerosol?
      A water jet alone would not have enough cooling efficiency for highspeed preparations. That’s why compressed air is added to create the spray. Due to the higher moistening capabilities of this small waterdrops, a much better cooling is ensured – in favour to the vitality of the patient’s teeth!

    Our service tips for you

    • Does my transmission instrument need maintenance?


      Whether straight and contra-angle handpieces, couplings or turbine handpieces – in daily operation it can happen again and again that transmission instruments suddenly fail. For people who want to be on the safe side and value the long service life of the products, we would like to point out the recommended annual maintenance. Regardless of this, there are various signs that indicate a need for maintenance or repair. Here are some examples of how you can determine the maintenance need for your transmission instruments:

      • High temperatures
      • Strong vibrations
      • Increased volume
      • Lower power/speed
      • Reduced bur holding force
      • Decreasing light intensity/light fluctuations
      • Impairment of spray intensity/spray fluctuations
      • Coolant failure or leakage

      If you notice one or more of the above-mentioned operating malfunctions, contact an authorised "W&H service partner".

    • Safety technical checks for medical devices


      To ensure safety of users, patients and third parties, medical electrical devices must be checked regularly. For this reason, the Medical Devices Act provides safety checks. During the check, it is determined whether a device is functional, electrically safe and in proper condition at the time of inspection. The safety check must be carried out every three years or according to the manufacturer's instructions. For W&H devices such as Implantmed or Piezomed, the safety check is mandatory every three years. National regulations can include exceptions for shorter inspection periods. In Germany, for example, the safety check has to be carried out every two years.

      The safety check may only be carried out by qualified companies and institutions. These companies confirm the proper functioning of the devices and thus ensure the safety of patients, users and third parties.

      The safety check is subject to all W&H stand-alone devices such as Implantmed, Elcomed, Piezomed, Pyon, Tigon/Tigon+ or Proxeo Ultra.

    • Maintenance at the touch-of-a-button


      After 35 seconds, our Assistina 301 plus leaves a perfectly maintained transmission instrument. The maintenance process starts automatically at the touch of a button. The automatic rotational lubrication ensures optimum distribution of the oil and that an even film of lubricant is created. Dirt particles are loosened and removed. The lifespan of the straight- and contra angle handpieces and turbines is significantly increased whilst service costs are reduced.

      But our Assistina 301 plus also needs a little care. Our tip: Check the functionality of your device once a week: the liquid level, the position and condition of the O-rings, the filter, and the tightness of the connections.

      The "weekly checklist" gives you an overview.

    • What are maintenance kits? And why are they so smart?


      Every product, whether in the private or professional field, is exposed to a certain amount of wear over time. This wear could only be visually disturbing or lead to a real defect. Maintenance kits can help, since they contain exactly the spare parts that need to be replaced – no more and no less!

      Maintenance kits are designed either for end users or for service partners and are tailored to a defined product. A popular example is our maintenance kits for W&H sterilizers, which are normally used after 800 or 4,000 sterilization cycles for the recommended service.

      • Service after 800 cycles: Do it yourself! The spare parts included in the maintenance kit can be replaced by the end user. The costs can be calculated exactly. The original spare parts contribute to the long service life of the sterilizer.
      • Service after 4,000 cycles: The service after 4,000 cycles can only be carried out by an authorised service technician or a specialist workshop. The device must be opened and the parts included in the maintenance kit must be replaced. The costs for this can also be calculated exactly.

      Maintenance kits thus offer absolute cost transparency. The advantage over purchasing individual spare parts is obvious. For information on all available maintenance kits, please contact your
      "W&H service partner".

    • Perfect cleaning – without tools


      Surgical interventions are a great challenge. In order to meet the high hygiene requirements, the W&H surgical straight and contra-angle handpieces of the S and WS series can be disassembled quickly and easily. Total simple – without tools. This not only facilitates thorough cleaning, but also extends the service life of your instruments. The surgical straight and contra-angle handpieces can then be reassembled just as quickly and easily.

      How to properly disassemble and reassemble our surgical contra-angle handpiece WS-75 is shown in this "video".

    Protective measures in the dental practice

    • Good hygiene management is an essential part of everyday work in dental practices.

      Especially nowadays, the focus on hygiene and protective measures for patients and staff has increased. Wearing protective masks and protective clothing are two important measures to reduce the risk of infection in the practice and during dental treatment.

      Possible risks of infection also include the "aerosols" released during dental treatment. The right protective gear can help to keep patients and staff save.

      Interrupting the chain of infection

      Within the next weeks we will guide you through the hygiene process to ensure best practice reprocessing of dental instruments and thus your personal protection.
      What is the chain of infection?

      The chain of infection is the way of transmitting an infection from one host to another. Hosts can be humans, animals, but also other environmental components. The transfer can take place mutually.

      The infection chain consists of six different links: first, the pathogen. In second place is the reservoir, where the pathogens replicate and can cause further infections. Third, the portal of exit, for example through sneezing or coughing (airborne infection) or other body fluids.

      The modes of transmission, the fourth link in the chain, take place indirectly by touching living beings or contaminated objects or directly, by smear infection. Now the portal of entry opens the door for the pathogen. This means that the pathogens eventually reach the next susceptible host through the mucous membranes of the eyes, mouth, nose, the digestive system or excoriations. People with a weakened immune system are particularly affected. (The time between contamination and onset of symptoms is called the incubation.)
      However, this chain of infection can be interrupted through various means and on each link. W&H is taking selective measures with Advanced Infection prevention Management Solutions.
