User information
- Use adequate supply of water spray in order not to damage teeth and fillings. The water should be distributed over the entire length of the working part. A deflection of the cooling jet can cause heat related damages.
- Additional cooling is required for FG instruments with a total length exceeding 19 mm and for instruments with a head diameter exceeding 2 mm.
- Immediately remove any instruments that are damaged, bent or do not run concentrically.
- Pressure should be 0.3 - 2N (30 - 200p) for FG-instruments and 2 - 5N (200 - 500p) for HP instruments; in other words work with as little pres- sure as possible.
- The turbine, right angle and hand piece must be in perfect technical conditions.
- Insert the instrument carefully and without using force. Miniature instruments should be inserted no further than the end of the cylindrical part.
- Avoid canting or levering when grinding.
- Observe the recommended speeds indicated in the table below and on the packages.
- Full speed should be reached outside the mouth of the patient. Technicians should run the hand piece at full speed before application to the product on which is worked.
Hygiene recommendations (disinfection, cleaning, sterilization and storage of the instruments).
- FG instruments must always be disinfected, cleaned and sterilized before they are used on patients.
- Immediately place used instruments in a special anti-corrosive disinfectant bath - but for a short time only, otherwise their colour code may come off. Do not use too aggressive products (hydrochloric acid, ...), they may corrode the instruments.
- Clean the instruments in an ultrasonic bath or under running water (preferably distilled water).
- After cleaning, immediately dry the instruments otherwise they can corrode.
- Before sterilization, place the instruments in stands and trays suitable for sterilization.
- Sterilize the instruments.
- After sterilization, keep the instruments in dust-free places. Instruments used for surgery should be kept in sealed containers.
