General Information for Use and Safety
acurata instruments are intended for the dental medical field and must only be used by dentists or respective experts who, due their training and experience, are familiar with the use of the products. The instruments are supplied non-sterile and have to be prepared prior to first use.
Information for use for dental rotary instruments
Use only technical and hygienic correct drives with a stable ball bearing! Carefully clamp the instruments as deep as possible and assure that the desired speed is reached prior to usage. Please note the maximum allowed engine speed as stated on the packaging label. Avoid levering or canting, otherwise there is risk of fracture. Pay attention that there is sufficient cooling (50 ml/min) otherwise there is risk of thermal dama-ge. FG-instruments with a total length > 19 mm and instruments with a diameter of the work element > 2 mm (ISO 020) need extra cooling. Separate blunt, twisted or damaged instruments immediately and do not use them again. Improper usage increases risk, higher wear and inferior work results!
The contact pressures should be light, do not exceed the maximum of 2N. Excessive contact pressures can cause damage to the instruments. In extreme cases the instrument can fracture! At the same time a higher heat development is generated. Overheating may harm the dental pulp, instruments wear faster and surfaces get coarser.
Polishers and instruments with long working part and respectively long, slender necks (e.g. instruments for micro preparation) or for specific application areas (e.g. crown separator, long chirurgical cut-ter): exceeding the maximum allowed speeds can cause oscillations (vibrating) or displacement (whippings). This can result in fracture or heavy damage. Non observance causes an increased security risk! Therefo-re pay attention to the maximum speed printed on the packaging labels · The respective maximum speed is a theoretical value given on the basis of the geometry of the instruments. The choice of the working speed is determined by the material subsequently to be used, the specific indication, the type of handpiece used and the contact pressures and is at user’s discretion.
