Diamond grit-coated ZENOSTAR diamonds and diamond coated ZENOSTAR polishers are designed for the
professional grinding and high-quality polishing of dental restorations by dentists after inclusion in the mouth.
There are 2 product-group sets:
a) ZENOSTAR Diamonds and
b) ZENOSTAR Polishers
Set a) includes a total of 4 diamond rotaries in a 2-grit system
ZENOSTAR Diamonds Football fine (379)
ZENOSTAR Diamonds Football extra fine (379)
ZENOSTAR Diamonds Kugel fine (801)
ZENOSTAR Diamonds Kugel extra fine (801)
The instruments have an FG shank according to ISO 314 and are used in a turbine. The fine grit is for pre-
liminary „grinding/eroding/cleaning". These instruments have red ring codes. The extra-fine grit is for „finer
grinding" and has a yellow ring code.
Set b) also includes 5 diamond polishers in a 3-grit system (coarse, medium, and fine):
ZENOSTAR Polisher Pre-polish (S head)
ZENOSTAR Polisher Pre-polish (L head)
ZENOSTAR Polisher Finish (S head)
ZENOSTAR Polisher Finish (L head)
ZENOSTAR Polisher Glossy (S head)
The diamond polishers have an RA shank according to ISO 204 and are fixed in a reduced angle (e.g. 1:3).
The colour-coded polishing instruments are to be used according to grit size as described below. To achieve
an optimal result, all polishing steps should be carried out in sequence (blue, red and grey).
1. Coarse grit (blue ZENOSTAR Pre-polish polisher, for smoothing after „grinding"),
2. Medium grit (red ZENOSTAR Finish polisher, for polishing) and
3. Fine grit (grey ZENOSTAR Glossy polisher, for „optimal shine").
Products for use in dentistry should only be used by dentists, doctors or trained professionals who are familiar
with them, know how to use them, and have specialist knowledge of the respective areas.
Instructi on s
All the instruments have been developed and constructed for specific uses. Improper use may cause damage
to the teeth, premature wear, and destruction of the instruments, and may also endanger the user, patient
or third party.
1. Correct use
Use only technically sound and thoroughly hygienic, serviced and cleaned turbines. The same applies to
handpieces and angle pieces.
Precise drive concentricity of both the turbine and the angle piece is required.
When using these products, make sure that you use sufficient cooling water (50 ml/min) and minimum
grinding pressure (2 N).
Fix the instruments as low as possible.
Bring the instruments to speed before placing them on the object.
Movements should be lightly circular where possible to avoid „bumps" and thermal damage.
Discard bent or non-evenly running instruments immediately.
Centre polishers where necessary to enable vibration-free operation.
Avoid unprotected contact with the instruments and parts at all times (use gloves).
The use of goggles is generally recommended.
Improper use leads to inferior results and increased risk. Rotating instruments should only be used
by qualified individuals.
2. Speed recommendations
The maximum permissible speed should never be exceeded. The recommended speeds and maximum per-
missible speeds vary from product to product. Please ensure for your own safety and the safety of others that
you are aware of the recommended speeds printed on the packaging.

3. Compressive force
Excessive compressive force can cause grinding tools to crack, become clogged or overheat.
Excessive compressive force can also damage the pulp through overheating.
4. Cooling
To prevent unwanted heat during preparation, use an air/water spray (min. 50 ml/min) to ensure sufficient
cooling.
FG instruments with a total length of over 22mm or a head diameter of over 2 mm will require additional
external cooling.
Insufficient water cooling can cause irreversible damage to the tooth and the surrounding tissue.
5. Cleaning and disinfection
Protection against infection is very important for both the patient and the treatment team. Disinfection and/
or sterilization of the used equipment are essential for safe and responsible use. Before use, the diamond
grinding instruments should be sterilized according to the manufacturer's instructions.
After use and before reuse, the following hygiene recommendations should be implemented.
Cleaning, disinfection, sterilization and storage of diamond grinding/polishing instruments:
Place used instruments immediately afterwards in a drill bath containing appropriate cleaning and
disinfecting solutions.
Use disinfectants and cleaning agents with corrosion protection. Pay close attention to the manufacturer's
cleaning and disinfecting instructions.
Check cleaned instruments before each use and clean them again if necessary.
The instruments can be ultrasonically cleaned. Use of drill stands or drill holders is recommended to avoid
damage to the instruments.
Sterilize the instruments in a chemiclave, autoclave or using hot air.
Note:
In order to prevent transmission of infectious pathogens, instruments contaminated with blood or dirt should
be disposed of carefully.
