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
-
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. -
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.
-

Assistina TWIN (7)
-
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.
-
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.
-
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 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.

Yes, providing that your W&H handpiece carries the relevant sterilization symbol.
-
Why should I use a prophylaxis contra-angle handpiece (WP-66 W)?
Generally, prophylaxis contra-angle handpieces feature a seal on the head that prevents the ingress of saliva and paste. This extends the lifespan of the contra-angle handpiece.
The most effective removal of discolouration that at the same time protects the enamel and dentine as much as possible, depends on the polishing speed, i.e. revolutions per minute, among other things. With a speed ratio of 4:1 (four revolutions of the motor mean one revolution of the cup), the revolution speed of the Prophy cup is reduced. This means during application, there is no risk of paste splattering. -
Can I use any Prophy cup that is available on the market for the WP-66 W?
In order to benefit from the advantages of the LatchShort system and to support the longevity of the contra-angle handpiece (WP-66 W), we recommend using W&H Prophy cups. However, it is possible for Prophy cups from standard latch systems (with a shaft of 2.35 mm) to be used.

Are there pathogens more resistant than mycobacteria?
Yes, the most difficult pathogens to eliminate are spores and prions, for to eliminate of which it is necessary to resort to the use of the autoclave for sterilization.
-
Are all pathogens equally resistant to disinfectants?
No, pathogens have very different resistances depending on the disinfectant substance used to try to eliminate them. The least resistant pathogens range from the encapsulated viruses up to mycobacteria, which are instead the most resistant and require a high level of disinfection to eliminate them.
-
What are the main aspects I have to consider when choosing a disinfectant?
There are three fundamental aspects that must always be considered when choosing a disinfectant: the desired efficacy, i.e. the ability of the product to be active on a wide range of pathogens, the expected efficiency, i.e. the ability of the product to reach its maximum effectiveness in the shortest possible time and, in the case of concentrated products, with the lowest possible concentration and finally the necessary compatibility, i.e. the possibility of using the product without the risk of damaging, destroying or invalidating its use of the tool or surface to be treated.
-
How do I choose the right disinfectant for my practice?
Depending on the categories of pathogenic microorganisms on which the disinfectant is effective, different levels of disinfection are distinguished; high, intermediate and low. In order to ensure total safety in the practice, for both patients and operators, the choice of disinfectant to be used must always fall on a product that ensures a high level of disinfection.
