USER GUIDE
- Ensure that the correct bur is selected (shape, size, and grit type) according to the preparation being carried out.
- Ensure that all handpieces, high-speed, and contra-angles are in perfect working order.
- Ensure that the bur's shank is fully inserted and adequately gripped by the handpiece.
- Ensure that you have selected the correct speed to ensure optimum performance and strictly observe the recommended speed constraints as shown below. Only apply the diamond grit to the surface once the recommended operational speed has been reached.
- Ensure that preparation work is carried out without exerting excess pressure. The recommended contact pressure range is 0.3-2N. Excess pressure will adversely affect the outcome of your preparation.
- Ensure that you use an adequate supply of water to prevent damaging the tooth structure, pulp, and any adjacent fillings. To achieve this, Crosstech recommends high-speed handpieces with three coolant spray jets, which spray the coolant along the entire length of the instrument's cutting surface. The minimum coolant supply is 50ml/min. Note that burs with lengths in excess of 21mm and a head exceeding 2mm in diameter require additional cooling.
- Avoid using blunt, damaged, bent, or non-concentric diamond instruments. They will adversely affect your preparation work and can damage the handpiece turbine.undefined
HYGIENE RECOMMENDATIONS
- All diamond burs must be disinfected and sterilized before use.
- After use, diamond instruments must be immediately immersed in a suitable cleaning agent. Use a cleaning agent that contains a corrosion inhibitor. Do not use strong acidic or alkaline disinfectants as these will adversely affect the instruments. If necessary, clean by mechanical means such as with a brass bristle brush, ensuring that absolutely no residue is left.
- Crosstech diamond burs may be cleaned ultrasonically and sterilized in an autoclave, chemiclave, or in hot air.
- After sterilization, keep burs in our dust-free bur blocks ready for reuse. Important: To prevent the spread of infectious germs, please carefully dispose of instruments contaminated with blood or saliva.
