How to use Dental handpiece correctly？
How to prepare dental handpiece at first stage?
Check the equipment:
Ensure that dental handpieces, foot switches, treatment tables and other equipment are connected properly and not damaged.
Check that the air pressure and water pressure systems are normal, and ensure that the compressed air input to the dental handpiece is dry and clean. If the air pressure is too low, it will cause the handpiece to turn weak; If the air pressure is too high, it will accelerate the wear of the bearing.
Exhaust drainage:
Before installing the handpiece, click the foot switch to eject the remaining air and water in the tube, and observe whether the outlet water is normal. This step is to ensure that the handpiece will not affect the work effect because of residual water or gas in the tube during use.
How to install and use dental handpiece?
Select handpiece type:
According to clinical needs to choose the appropriate dental handpiece, such as rotary, press, push and so on. At the same time, according to the different tooth position and the different shape of the spare hole, timely replace the handpiece and the diamond bur.
Install handpiece:
Screw handpiece: Put the handpiece on the treatment table, install the diamond bur, gently tighten with the handpiece key, pay attention not to too much force, in place.
Button type (gland type) handpiece: press the button on the head of the handpiece, you can load and unload the diamond bur, relax the button, the diamond bur is clamped. Install the diamond bur and test it by hand.
Adjust air and water pressure:
Adjust the air pressure to between 0.2-0.25kgf /cm² (or 0.2-0.22mpa) to ensure that the handpiece can rotate normally and does not wear the bearing excessively.
Adjust the water pressure to the right flow rate to ensure that the handpiece can form an even spray during operation, which helps to cool and clean.
Operation specification:
Use must be careful, avoid brutal operation, do not drop the handpiece to the ground.
No matter how the Angle, it should follow the way of lifting up and down to operate, so that light touch and point, avoid lateral force.
Use the improved pen to hold the handpiece, find a stable fulcrum, intermittent operation.
diamond bur Management:
The use of sharp diamond burs, blunt diamond burs not only time-consuming and laborious, but also easy to cause damage to the handpiece and increase the patient's pain.
Often check whether the diamond bur is loose, so as not to cause a flying diamond bur accident. After the diamond bur is installed, it must be pulled and confirmed firmly to avoid the diamond bur flying out if it is not inserted deep.
When loading and unloading the diamond bur, it must be carried out in the state of fully open the clamp spring, so as not to damage the clamp shaft. At the same time, avoid exposing the diamond bur too long.
Alternate use:
When the one-time workload is too large, two handpieces should be used in turn to avoid excessive load and damage to the handpiece.
Check air pressure and water pressure:
The air pressure and water pressure will change with the use of the treatment table, and it is necessary to check frequently to ensure the normal use of the handpiece.
How to maintenance dental handpiece?
Timely cleaning:
It should be cleaned as soon as possible after use to avoid the solidification of dirt and difficult to clean. Before unloading the diamond bur, clean the debris on the working head with water mist; Then scrub with 75% alcohol or clean with an ultrasonic handpiece cleaner. The specific method can be determined according to the specific situation of each clinic.
Remove the diamond bur:
After use, when going to the diamond bur, you only need to loosen the key (turn) 1/4 turn to avoid too much loosening leading to damage to the three-lobe spring.
Lubrication maintenance:
The use of air injection tank for lubrication, it can not only lubricate the handpiece but also clean the bearing and wind wheel. Note that the pneumatic injection tank must be used vertically, with each injection for 2-3 seconds. It is strictly forbidden to lubricate with industrial lubricating oil to prevent poisoning of patients.
handpieces that are not used for a long time should be fully oiled and sealed.
How to deal with malfunction of dental handpiece?
If the handpiece does not turn, slow speed, poor water supply and other faults, should be checked and repaired according to the corresponding steps. For example, poor water supply may involve problems with pipelines, interfaces, handpiece bodies or shafts; The diamond bur easy to fall off may be related to the choice of the diamond bur, improper installation or collision deformation of the handpiece head; The handpiece does not turn or the speed is slow, which may be related to low air pressure, lack of oil or damage to the bearing.
Through the above detailed steps and precautions, you can ensure the correctness and safety of the dental handpiece during use, thereby improving the efficiency of treatment and extending the service life of the equipment.
