  • W&H Osstell ISQ module (7)
    • 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
    • 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
    • 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.
    • 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.
    • 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.

  • Piezomed Instrumenter (4)
    • 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
      a. Different thread
      b. The Piezomed instrument detection cannot detect third-party instruments

Vedligeholdelsesudstyr

  • Assistina TWIN (7)
    • 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.
    • 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.
    • 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.
    • 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 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. Quick Connect adaptors ISO and RM can be used for the Assistina TWIN instead. An overview of all adaptors is available on the product website.
  • Assistina ONE (6)
    • How do you replace the ONE Care Set?
      The two cartridges and the filter can be changed easily without any tools. 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.
    • What instrument adaptors are available for the Assistina One?
      All adaptors that are suitable for the Assistina 3x2/3x3 can also be used in the Assistina One. There is only one exception: the RM/ISO adaptor for the Assistina 3x2/3x3 is not compatible with the Assistina One. Quick Connect adaptors ISO and RM can be used for the Assistina One instead. An overview of all adaptors is available in the product website.
    • Why does the Assistina One have a HEPA filter?
      During the maintenance process in the Assistina One, 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 legislation 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.
    • How does the user know when the ONE Care Set needs to be replaced?
      The ONE Care Set must be replaced when the cartridges are empty. The levels can be checked thanks to the device's fill level indicators, located on the right and left sides.
    • How often does the ONE Care Set needs 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. 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.
    • Why there is no rotational lubrication option in the Assistina One?
      The oil is atomized in the Assistina One before it 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.

  • Osmo (1)
    • Which water quality should I use for my sterilizer?
      Answer: The water quality for sterilizers is internationally specified by standards and directives. The reasons for this are that your sterilizer can be seriously damaged by it or the sterilization can be jeopardized. Consequently, only water with conductivity of less than 10 µS/cm in North America and 15 µS/cm for the rest of the world should be used for your W&H sterilizer. The Water treatment devices Multidem and Osmo are especially designed to prepare suitable water (see chapter “Water quality” in the Instructions for Use).

    • Lisa 17/22
      When the sterilizer is connected to an automated water supply system: there is no clean water in the tank, but the automatic water filling does not fill the water.
      POSSIBLE CAUSE
      Water fill system not connected
      SOLUTION
      Connect the water fill system to the sterilizer (see ANNEX 7 for water quality requirements).

      POSSIBLE CAUSE
      When the water fill system attempted to fill the tank, water was temporarily unavailable
      SOLUTION
      Since water tank filling is attempted only once in-between cycle execution, this event inhibits water feeding. Switch the sterilizer OFF and then ON again.
      Check the external water supply system.
      Check for water leaks from the sterilizer.

      POSSIBLE CAUSE
      Faulty MIN water level sensor in the clean water tank
