W&H Osstell ISQ module (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 '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.
isq scale

Where can I buy the SmartPegs?

Please contact your local W&H UK partner
A voucher will be included with any unit purchased, enabling the purchaser to request 5 free SmartPegs.

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 can be upgraded with the W&H Osstell ISQ module

Can the Implantmed unit be upgraded by the surgeon or does it require a technical specialist?

The module is easily attached 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

Piezomed Instruments (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. 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 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.

Are previous Implantmed motors compatible with the new Implantmed or vice versa?

No. The new motor has a new technological basis and is the shortest available

What does the LC in EM-19 LC stand for, is there an LED in the motor?

The LC stands for Light Contacts. This means that we have integrated an electrical connection into our new motors. The Light Contacts deliver power to our new contra-angles to offer our customers the best light at any rotation speed. For oral surgery handpieces from W&H, the LED remains in the head of the contra-angles

Can current contra-angles be attached to new motors?

Yes. All W&H surgical contra-angles and handpieces can be attached to the new motor EM-19.

Can the new contra-angles be attached to old motors?

No. In order to deliver the best balance we shortened the inner coupling length. Therefore surgical contra-angles with only the 'L' suffix cannot be attached to old motors

Are old cable foot controls compatible with the new unit or vice versa?

No. The new cable foot control S-N2 is based on the industrial CAN standard, therefore connecting the old foot control S-N1 is not possible.

Should I pre-wrap and how long can I store my instruments after sterilization?

Under current UK decontamination guidance, with a type B vacuum cycle, instruments should be pre-wrapped and once sterilized can be stored for up to 12 months. Wrapping should take place shortly after washing and disinfection. Under current UK decontamination guidance, with a type N cycle, instruments should not be pre-wrapped. Once sterilized, instruments can be immediately aseptically wrapped and stored for up to 12 months. Instruments should always be dry before they are placed in the purpose-designed packaging.

What is validation?

Validation is a series of tests carried out with the use of independent specialist test equipment, as is necessary to demonstrate that the physical conditions required for sterilization, thermal disinfection and/or cleaning (i.e. temperature, pressure, time) are achieved.

What periodic tests do I need to carry out on my Lisa/Lina?

Periodic testing is set out in the current national decontamination guidance document. In addition to a weekly safety inspection and air leakage test, a daily test should be performed by the operator or user and will normally consist of: - A steam penetration test (W&H recommend the Helix Test) - An automatic Control Test Note: These tests may be carried out at the same time. Additional information relating to these tests and how to carry out these tests can be found on the Video Guides section of this web site.

Do I need to document the results of all periodic tests?

Yes, all tests performed by the operator or user should be recorded in a logbook with the date and signature of the individual how carried out the test. Every Sterilizer and every thermo washer disinfector should have a logbook (file) in which test details pertaining to the lifecycle of the equipment (from purchase - disposal) are recorded. A logbook is provided as standard with the Premium Careplus Service Contract from W&H, or as an optional extra with the Premium Care Service Contract.

How long should I Keep periodic test records?

Under current national decontamination guildance, all audit documents should be stored for at least two years and they should not be removed from the premises or destroyed.

Does my Lisa/Lina need to be commissioned from new?

Yes, validation is needed for new equipment at installation and annually thereafter. It will also be necessary to validate equipment after any major repairs have been carried out.

Who should I use to carry out validation and maintenance on my Lisa/Lina?

All validation and maintenance should be undertaken by the Competent Person (Decontamination) or Competent Person (maintenance).

How do I change consumable components on my Lisa/Lina?

Information and videos relating to consumable components and how to replace them can be found on the Consumables & Accessories and Video Tutorial section of this web site.

How do I clean the water tanks and what products should I use?

Information and videos relating to the cleaning of the water tanks and cleaning products can be found on the Video Tutorial section of this web site.

What water quality should I use with my Lisa/Lina?

The use of good quality water in your W&H sterilizer is required to prevent the formation of lime-scale within the internal components. Lime-scale can seriously harm your sterilizer and therefore good quality water with a conductivity reading of not more than 15µS should be used with your W&H sterilizer.

Should I call the service station before sending equipment for repair?

If you are not sure what the cause of the problem is, it is better to call the service station and talk to a technician. Together with the technician you can determine what needs to be sent in, or sometimes the problem can even be resolved over the phone.

How often should I de-scale my Thermoklenz?

Water hardness can differ depending of the region in which the unit is located. Carrying out a water hardness test will enable you to gauge how hard the incoming water is. The frequency of de-scaling cycles will depend on the water hardness and the number of cycles run per week. W&H recommends that at least one de-scaling cycle be run each week. More frequent de-scaling cycles should be run if the washer disinfector has a heavier workload or if the water is hard. Additional information relating to these tests and how to carry out these tests can be found on the Video Tutorial section of this web site.

Do I need to carry out periodic testing on my Lisa/Lina?

Yes, testing is an integral part of ensuring that a small sterilizer consistently performs to operating parameters set during the machines commissioning. Failure to carry out routine periodic tests and maintenance tasks could compromise safety and have legal and insurance-related implications for the registered Manager.

Can an external apex locator be operated with the Entran?

We recommend taking measurements with an external apex locator directly on the file, if this is uncoupled.

For which file systems can Entran be used?

You can use any file systems on the market which are suitable for rotating preparation, have a 2.35 mm standard sheath and a torque of at least 0.5 Ncm.

What happens if the file cannot be freed using the auto forward / auto reverse mode?

Once the set torque is reached, the set mode (auto forward or auto reverse) is activated and Entran makes five attempts to remove the file. If it is not successful, Entran stops. It is recommended to restart it. If the file still cannot be removed, it should be released from the chuck system and removed manually.

Can I use Entran with a Gates bur?

It is not recommended to use Entran with a Gates Glidden bur as the low speed is insufficient to guarantee high removal efficiency.

Where can I find the Entran torque settings that correspond to my file system?

In addition to the overview of the values on the file cards included in the Entran's scope of delivery, the file manufacturers also provide information on the files' maximum torques.

How long can you work on one battery charge?

One fully charged battery is enough for over 20 treatments.

Can the Entran stop working during treatment if the battery runs out?

When the battery indicator starts flashing, there is enough time to finish the treatment. Afterwards, the ENTRAN needs to be charged.

How long does it take to charge the battery?

If the battery is completely dead, it will take approximately 90 minutes to charge fully.
