  • Assistina TWIN (9)
    • Je nutné před odesláním zařízení do servisu nejprve kontaktovat servisní středisko?
      Pokud si nejste jisti, co je příčinou závady, je lepší servisní středisko kontaktovat a záležitost konzultovat s technikem. Technik Vám může poradit, jakou část zařízení stačí zaslat, a někdy je dokonce možné ve spolupráci s technikem problém okamžitě vyřešit.
    • Which processing steps are carried out in the Assistina TWIN?
      • Cleaning the spray channels with W&H Activefluid
      • Lubricating the rotating parts with W&H Service Oil
      • Throughout the maintenance process, potentially contaminated aerosols are extracted from the process chamber and the exhaust air is cleaned using a HEPA filter.
    • What instrument adaptors are available for the Assistina TWIN?
      All adaptors that are suitable for the Assistina 3x2/3x3 can also be used in the Assistina TWIN. There is only one exception: the RM/ISO adaptor for the Assistina 3x2/3x3 is not compatible with the Assistina TWIN. The HPI adaptor can be used for the Assistina TWIN instead.
    • Why does the Assistina TWIN have a HEPA filter?
      During the maintenance process in the Assistina TWIN, the rotating parts are lubricated with oil and the spray channels rinsed with cleaning solution. These liquids are introduced to the handpieces using compressed air, which produces aerosols that may contain potentially contaminated body fluids (e.g. blood and saliva). In order to ensure that the apparatus poses no risk to the user, the patient or third parties, the law stipulates that aerosols must be prevented from leaking out of the apparatus. We make sure of this by using active suction and the HEPA filter. This HEPA filter must of course be changed regularly, which is why the lifespan of the filter is matched exactly to the capacity of the two cartridges. The HEPA filter therefore reaches the end of its service life once one set of cartridges has been used.
    • What does HEPA mean, and what is filtered out of the air?
      HEPA is short for 'High Efficiency Particular Air', and the filter is classified as HEPA class E11. This means that the filter retains all particles larger than 1 µm, which includes, among other things, a wide range of bacteria and viruses, suspended particles such as dust and respirable aerosols.
    • How does the user know when the TWIN Care Set needs to be replaced?
      The intelligent process monitoring system documents the number of maintenance cycles that have been performed, thereby automatically calculating the number of instruments that can be serviced with the remaining quantity of fluid. The user receives an alert 300 cycles before the cartridge needs replacing (the oil and cleaner LEDs on the top of the unit turn yellow in colour).
    • How often does the TWIN Care Set need to be replaced?
      The consumption volumes for each instrument are 0.07 ml of oil and 0.07 ml of cleaning solution. This gives a maximum capacity of 2857 cycles. In reality, the value is around 2800 to 2850 cycles, as initial filling is also required and the fill quantity of the cartridges is subject to certain tolerances that are regulated by the applicable standards.
    • How do you replace the TWIN Care Set?
      The two cartridges and the filter can be changed easily without any tools. As with the Assistina 3x2/3x3, the fluid is supplied via tapping needles in the bottom of the cartridge spaces that penetrate the cartridge membrane, thereby drawing the fluid out of the cartridge. The two cartridges have different shapes to ensure that the two fluid types cannot be mixed up. In addition, it is only possible to install the HEPA filter incorrectly by using force, which is not necessary.
    • Why is there no rotational lubrication option in the Assistina TWIN?
      The oil is atomized in the Assistina TWIN before it is enters the instrument. This ensures full coverage of the gear parts, eliminating the need for technically complex and time-consuming rotational lubrication. However, there is no negative impact on the maintenance quality: the results of a maintenance operation correspond to those achieved with the Assistina 301 Plus.

  • Piezomed (8)
    • How does it work to wirelessly control the Implantmed and the Piezomed?
      W&H introduces a new concept in oral surgery and implantology. Via dongles (receiver), which can be connected to the unit by the doctor, the wireless foot control S-NW communicates with the surgical units of W&H.wireless foot control
    • How long is the useful service life of the instrument detection?
      The instrument detection is located in the LED socket and is automatically replaced at the same time as the LED socket.
    • Is it necessary for the torque driver to engage audibly when tightening the instrument?
      Yes, it must engage audibly once, as otherwise the required torque is not achieved.
    • How long is the useful service life of the LED?
      The user must replace the LED socket as soon as the protective coating on the LED discolours and the luminous power is impaired as a result. The length of time this takes can differ depending on the type of steriliser or sterilization process.
    • Can Piezomed instruments also be used on third-party devices?
      No
      a. Different thread
      b. Third-party device cannot find the correct resonance point – instrument fails to oscillate
    • How long do the instruments last and when should they be replaced?
      The useful service life of the instruments is determined by the length of time they are used reprocessing and sterilization cycles have only marginal influence.
      a. Instruments need to be replaced
      - If there is a loss of power while working
      - Where there is visible damage on the working part or the shank of the instrument.
      b. Saws must be replaced if
      - Teeth are broken off
      - Teeth are worn
      c. Diamond-coated instruments must be replaced
      - As soon as the diamond coating is worn
    • How are the instruments prepared for cleaning?
      a. Preparation in the ultrasonic bath:
      - Place the instruments in the instrument tray and lower into the ultrasonic bath.
      - Use cleaning agents and disinfectants suitable for hand instruments (probes, mirrors, forceps, etc.).
      DO NOT USE a bur bath, as this is very aggressive.
      - After cleaning in the ultrasonic bath, rinse adequately with water to remove any remnants of the cleaning agent and disinfectant from the coolant channels.
      - Blow dry with compressed air after rinsing
      - Replace dried instruments in the instrument tray and package for sterilization

      b. Mechanical preparation in the cleaning unit and disinfector
      - Use the cleaning adapter for cleaning units and disinfectors (see Instructions for Use – Accessories)
      - After preparation in the cleaning unit and disinfector, check that the coolant channels are dry and, if necessary, dry again with compressed air.
    • Can third-party instruments be used on the Piezomed?
      No

  • Proxeo TWIST (1)
    • Proč je nutné používat profylaktický kolénkový násadec (WP-66 W)?
      Hlavním důvodem je, že hlavička profylaktického násadce je opatřena těsněním, které zamezuje vniknutí slin a pasty. Tím se zachovává maximální životnost kolénkových násadců.

      Aby při odstraňování zabarvení byla do maximální míry zachovávána zubní sklovina a dentin, je nutné při leštění mimo jiné nutné používat optimální otáčky. U profylaktického násadce jsou otáčky sníženy díky převodovému poměru 4:1 (čtyři otáčky motoru na jedno otočení kalíšku), při kterém nedochází k rozstřikování pasty.

  • W&H Osstell ISQ modul (7)
    • What does ISQ stand for?
      The abbreviation ISQ stands for Implant Stability Quotient. It is a value between 1 and 100 and gives the surgeon an insight of the implant stability after placing the implant. With the ISQ value the surgeon can monitor the osseointegration.
    • How does the measurement of the ISQ work?
      > To measure the ISQ of an implant, you first screw a so called SmartPeg into the placed implant. The SmartPeg, with its magnet on top, works like a small tuning fork. The magnet on the SmartPeg is ‘hit’ with magnetic pulses, from the probe, which makes the SmartPeg vibrate. Due to the stiffness in the interface between the implant surface and the bone the SmartPeg will vibrate accordingly. The more dense the bone is the higher stability and the higher ISQ value.

    • Where can I buy the SmartPegs?
      Please contact your local W&H partner
      The sale of SmartPegs will be defined per country
      The surgeon will receive 5 free SmartPegs. A voucher will be provided with the delivery of the product.
    • Is the ISQ scientifically proven?
      The Osstell ISQ technology is proven by over 700 scientific studies. These studies have shown, that torque and ISQ correlate.
    • What’s the difference between torque and ISQ?
      Torque is a one time, static measurement at the time of placement of the implant and cannot be repeated later on in a non-invasive way. Osstell ISQ measures the lateral stability of the implant and the measurements can be repeated in a non-invasive, dynamic way to monitor the development of osseointegration.
    • Is every new Implantmed compatible with the W&H Osstell ISQ module?
      Yes. All control units SI-1023, SI-1015 and SI-1010 can be upgraded with the W&H Osstell ISQ module
    • Can the surgeon upgrade the unit by themself or does the unit need technical service?
      The surgeon or dental nurse can easily attach the module to the right side of the Implantmed with the help of the provided quick manual. The module is plug-n-play via a USB connection.Implantmed with ISQ model comparison
