Premium Dental Adjustable Torque Ratchet Wrench
- Premium Quality Mechanism
- Made in Germany!
- 6.35mm Hex
- Compatible with: Alpha Bio®, Nobel Biocare® & many other systems as well.
This wrench was designed for use in dental applications. It should only be used by qualified personnel.
It is used to screw in dental implants and to extract them at pre-adjusted torque levels.
Setting the dental implant torque wrench: The desired amount of torque can be set with the adjustment nut (1).
A scale (2)in the front of the wrench indicates the amount of torque that can be applied at that setting. 5 Ncm increments are clearly marked on the sides of the scale (from 10 to 45 Ncm).
Blocking the Torque: Setting the torque to its maximum effectively disables the torque feature.
Do not screw too tightly.
Storage: Store in a relaxed position, not exceeding 20 Ncm.
Force should only be applied at the head of the adjustment nut (1)
When reaching the desired torque, the wrench bends around the pivot (3) in the ratchet head and gives off an audible click. At this point stop pressing on the wrench – otherwise it will be damaged.
The wrench will return to its normal orientation when you stop applying force.
The wrenches are not sterilized prior to shipping.
They must be cleaned, disinfected and sterilized before use.
When cleaning, do not use abrasive detergents and do not apply excessive pressure.
To avoid damage do not clean with wire brush or metal pads.
Use only cleaning and disinfectant solutions with a ph between 5 and 10.
Please follow the cleaning / disinfectant manufacturer’s instructions
Frequent but careful cleaning has little effect on the life of the ratchet.
Product life is determined by wear.
Recalibrate the wrench once a year. The wrench must be cleaned and sterilized after service.
If contamination is suspect at any time, disassemble the wrench and clean all the parts thoroughly.
Clean the parts with cold water and a soft disinfection brush until no residue is visible.
Manual Cleaning and Disinfection
Ultrasound Cleaning Bath
Add a cleaning solution to the ultrasonic bath. Place the parts in a wire basket and then insert the wire basket in the bath. Set the bath to 35-40 kHz and a temperature of 50⁰C. Clean for 3 minutes. Make sure that the parts are totally immersed.
Post Bath Treatment
Rinse the parts in cold water, preferably de-ionized water. Dry the parts on a lint-free towel.
The scale, adjusting nut, and ratchet head should be insufflated by using sterile compressed air.
Automated Cleaning and Disinfection
Washer / Disinfector
Place the cleaned dental implant torque wrench parts in a wire basket. Do not overload the basket.
Start the program. Rinsing is typically followed by a chemical cleaning at 40⁰ to 60⁰C. Chemical residue is cleaned by another rinse cycle. Corrosion due to neutralizing agents must be avoided. Disinfection is reached at 90⁰ to 95⁰C. Parts are then treated with deionized water followed by drying.
The parts should be removed from the washer/disinfector immediately after the end of the program.
Post-Cleaning Maintenance, Control and Functional Testing
Cool the parts down to room temperature and visually inspect the parts for residues and other contaminants. If necessary, repeat the cleaning process.
Apply a tiny drop of handpiece oil to the parts drawing (joint & thread)
Assemble the wrench and functionally test it.
Recommended Sterilization Method
Loosen the ratchet completely prior to sterilization
Method Fractionated pre-vacuum process (according to ISO 17665)
Temperature Heat up to 134⁰C (137⁰C Maximum)
Pressure 3 pre-vacuum phases with at least 60 millibar pressure
Holding Time at least 5 minutes
Drying Time at least 10 minutes
After sterilization check the packaging of the sterilized instruments for damage. Check the sterilization indicators.
Store the sterilized wrenches in a dry, dust-free, corrosive vapor-free area at a moderate temperature.
Do not loosen the Adjustment Nut Screws (6) as that will cause torque loss and a loss of calibration.
