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.

What is validation?

Validation is a documented procedure for collecting, recording and interpreting data required for proving that a procedure constantly complies with the specified specifications. W&H sterilizers feature a process evaluation system, which continually monitors the stipulated specifications (temperature, pressure and time).

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

Country/regional specific laws and guidelines referring to periodical testing or routine monitoring are individual and must be considered. Our recommendation for periodical testing is mentioned in the delivered IFU and depends on the integrated features in your sterilizer.

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

W&H recommends to record all periodic tests, repairs and modifications on the sterilizer in the logbook including date and signature of the person who carried out the test or other activity.

How long should I archive the documentation of regular tests?

Keep the results according your country/regional specific laws and guidelines and the definitions in your QM. Those records can be of assistance in case of service as well.

Does my Lisa/Lina sterilizer need any periodic qualification/validation?

Validation generally comprises a range of tests defined in internationally recognised standards. These tests begin for every device with the factory tests at W&H. In addition, corresponding documentation is included with your device. Prior to commissioning the device at your premises, the technician performs further checks to ensure the device functions correctly. Then, depending on the national/regional laws and directives, the device must be subjected to a so-called renewed performance qualification at regular intervals. For further information, please contact your dealer.

Whom should I get to validate and maintain my Lisa/Lina sterilizer?

All validation and maintenance work should be performed by a qualified individual.

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

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.

Which water quality should I use for my Lisa/Lina sterilizer?

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 jeopardised. Consequently, only water with conductivity of less than 15 µS/cm should be used for your W&H sterilizer. The Multidem system (LINK) is especially suited to preparing suitable water.

Should I pouch wrap my instruments and how long can I store them after sterilization?

To ensure that your instruments are stored in a sterile state from their successful sterilization until they are used, W&H recommends packing them in suitable sterile barrier systems from even before sterilization. The recommended storage periods can be found in your national/regional laws and directives. For further information, please contact your dealer.

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 it can be determined what needs to be sent in and sometimes it is possible to even solve the problem right away.

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 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.
isq scale

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

Piezomed Instruments (5)
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.

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.

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 a 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 contra-angles with only an L suffix cannot be attached to old motors

Can our customers disassemble the new contra-angles

Yes. At W&H the letter "S" always communicates, that the surgical contra-angle is disassemble. The letter "I" communicates, that the surgical contra-angle cannot be disassembled (e.g. WS-75 L vs. WI-75)

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. So connecting the old foot control S-N1 is not possible.

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

Can previous Implantmed units be retrofitted with the wireless foot control

It depends but basically yes. The following units can be retrofitted
Implantmed SI-923 REF16929000
Implantmed SI-915 REF16929001
Elcomed SA-310 REF15933100/15933101/15933102/15933103
Please contact your local W&H Partner to find out if the wireless foot control is already registered in your country

Why doesn't the light on my LED G contra-angle handpiece work when I am positioning an implant?

The generator in the contra-angle handpiece requires at least 300 rpm to produce enough electricity for the LED. The rotary speed is between 15 and 50 rpm when positioning an implant.

Is it possible to set the motor speed with the program for positioning an implant?

No, the speed in program P4 is 15 rpm when in forward operation and 30 rpm in reverse operation. In program P5 (thread cutter function) the speed is 20 rpm in both forward and reverse operation and only the torque can be set.

Does the motor need to be greased?

No, the Implantmed/Elcomed motor does not need greasing. The motor bearings require no maintenance. Any additional greasing would reduce the service life of the bearings.

How can I adjust the torque?

The torque can be adjusted in P4 & P5 only. In- or decreaseing is done via either "+" or "-" button. A detailed description (factory settings, adjstable range,…) can be found in the user manual.

Can handpieces from another manufacturer be used on a W&H surgical motor (implantmed / elcomed)?

For applications which do not require accurate torque (drilling, grinding,…), any handpiece with ISO 3964 connection can be used. Please be informed that hand pieces from other manufacturers might not be able to handle the torque of your unit/motor and therefore might get damaged.

Can other brands of tubing be used?

Not recommended. Due to different specifications (material, dimensions) it could cause problems like leakage, insufficient cooling or even damage the unit. For propper tubing see "correlation of tubing" or user manual.

How to insert irrigation tube?
