Question: Can current contra-angles be attached to new motors?
Answer: Yes. All W&H surgical contra-angles and handpieces can be attached to the new motor EM-19.

Question: Can the new contra-angles be attached to old motors?
Answer: 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.

Question: Can our customers disassemble the new contra-angles?
Answer: 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)

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

Question: Can my W&H handpiece be processed via sterilizer.?
Answer: Yes, providing that your W&H handpiece carries the relevant sterilization symbol.

Question: Which material is used at W&H surgical instruments?
Answer: Internal and external parts are of high quality stainless steel (including the contra-angle handpiece head).

Question: Can LED instruments with generator be sterilized?
Answer: Yes, W&H handpieces with LED and generator are both sterilizable and thermo disinfectable .

Question: Is the removable spray clip of my surgical hand piece sterilizable?
Answer: Yes. In order to extend the live span of the clip, W&H recommends to remove the clip from the hand piece and sterilize it separately (hand piece and clip in one pouch but separated).

Question: What is the difference between WI-75 and WS-75?
Answer: Both assure maximum performance. The WS-75 can be dismantled and therefore it can be cleaned more thoroughly.
