1. The best approach is to use a slow circular motion over the affected area until sound tooth structure is revealed The tooth is now ready to be filled in the normal way For larger cavities a combination of the AQUACUT QUATTRO and a rotary instrument may be of benefit This is because fluid abrasion is a technique designed to produce a very conservative cut with a working area of less than 2mm diameter Finally the surface of the cavity should then be finished using the AQUACUT QUATTRO to ensure a suitable key for the bonding agent NOTE Fluid abrasion is not a suitable technique for shaping undercuts for amalgam restorations Traditional rotary instruments should be used for this application 8 Aquacut Quattro TREATMENTS REMOVAL OF COMPOSITE RESTORATIONS Settings Powder 53micron Aluminium Oxide red container Cutting Nozzle 0 6mm diameter or 0 8mm diameter Cutting Speed 4Bar to 6Bar Powder Flow 3to5 The AQUACUT QUATTRO is very useful for the removal of old composite restorations Hold the cutting nozzle at an angle of about 45 Deg to the surface of the old composite restoration and about 2mm or 3mm from the surface The best approach is to use a slow circular motion over the old restoration beginning at the edge particularly at the failed margin until all the old composite has been removed and the cavity preparation completed The new restorative can now be applied in the normal manner without any furth2.

7. s of particular use for treating fissure caries To treat the caries use the Settings as listed above Hold the cutting nozzle about 2mm from the surface of the tooth and direct the particulate beam at the caries Use it in short bursts sweeping it along the vein until all the dark caries is removed and the sound tooth structure Is revealed The beauty of this procedure is its speed and the absolute control possible ensuring that the minimum amount of tooth structure is removed The newly prepared surface being dry and abraded is now ready for restorative materials Normally local anaesthetic is not necessary for the above treatment NOTE If there is soft caries present in the dentine a rotary instrument may have to be used or use the Sodium Bicarbonate on cleaning setting This is because soft and moist caries are resilient and therefore not so effectively removed by the use of fluid abrasion Aquacut Quattro 7 TREATMENTS CAVITY PREPARATION Settings Powder 53micron Aluminium Oxide red container Cutting Nozzle 0 6mm diameter or 0 8mm diameter Cutting Speed 4Bar to 6Bar Powder Flow 3to5 The procedure for the preparation of a cavity with the AQUACUT QUATTRO will depend on the size of the cavity and the extent and type of caries For small cavities the cutting nozzle should be held at an angle of between 35 Deg and 45 Deg to the surface being abraded and about 2mm or 3mm from the surface
8. teeth Where the teeth have been stained by coffee and or smoking fluid abrasion comes into its own The fine particles of sodium bicarbonate penetrate the micro crevasses of the tooth surface and the particulate beam easily follows the contours of the tooth surface enabling the staining to be removed very quickly and with no discomfort to the patient The settings as listed above will create a wide particulate beam of high velocity and medium particulate density This is to prevent removal of the tooth enamel yet provide sufficient power to remove staining The cutting nozzle should be held approximately 4mm from the surface of the tooth at an angle of approximately 45 Deg By moving the nozzle further away from the surface of the tooth the rate of removal of staining can be slowed down Move the handpiece slowly over the tooth surface The most effective way to use fluid abrasion for this procedure is to use the handpiece of the AQUACUT as if it were a paintbrush making light strokes across the surface of the tooth until the surface is clean With experience the dentist will be able to work with a high degree of control the learning curve being similar to that when first using a high speed drill 6 Aquacut Quattro TREATMENTS FISSURE CARIES TREATMENT Settings Powder 29micron Aluminium Oxide blue container Cutting Nozzle 0 5mm diameter or 0 6mm diameter Cutting Speed 3Bar Powder Flow 1 The AQUACUT QUATTRO i
9. y of use Generally there is no need to give a local anaesthetic as fluid abrasion is in most cases quite painless however always offer anaesthetic to nervous patients NOTE The following pages give a range of settings for each procedure Start at the lower end of the recommended settings and work up as you become more proficient Increasing the air pressure or the abrasive powder flow will increase the cutting speed or cleaning rate and conversely decreasing either of the settings will decrease the cutting speed or cleaning rate If the air pressure is increased but the abrasive powder flow decreased then the cutting speed will remain substantially the same but with less powder out flow from the working area If the air pressure is decreased but the abrasive powder flow Increased then the cutting speed will remain substantially the same but the patient will be subjected to a less aggressive treatment which is ideal for use on sensitive areas 4 Aquacut Quattro PREPARATIONS BEFORE TREATMENT WARNING BEFORE OPERATING WITH AQUACUT THE PERSON OPERATING THE UNIT ANY ASSISTANTS THE PATIENT AND ANYONE ELSE IN THE OPERATING AREA MUST WEAR EYE PROTECTION TO BS EN 166 IF 415 AND EXCEPT FOR THE PATIENT THEY MUST ALL WEAR RESPIRATORY MASKS TO EN 149 FFP2S Itis recommended that a light coating of petroleum jelly is smeared around the patient s lips to prevent cracking and to attract some of the out flow of abrasiv
