What are the most common problems with dental high-speed handpieces?
Dental high-speed handpieces play a vital role in dental offices and hospitals, but they often encounter some problems during use. Here is a brief analysis of the most common problems with dental high-speed handpieces.
The head of high-speed handpiece can not clamp the diamond bur or can not be taken down?
Phenomenon: The diamond bur cannot be firmly clamped in the handpiece, or it is difficult to remove from the handpiece when needed.
Reason: 1. diamond bur tail diameter is small, does not meet the requirements.
2. Dirt plugs the chuck groove, causing the chuck to fail to close.
3. The three-lobe spring is worn and damaged.
4. The diamond bur and clamping mechanism rust dead.
The solution:
1. Replace the standard diamond bur.
2. Clean the chuck to remove dirt.
3. Replace the worn or damaged three-lobe spring.
4. Replace the rusty diamond burs and clamping mechanism, and regularly clean and maintain the oil injection.
What will make water supply or gas supply problem?
Phenomenon: During the use of handpieces, there are problems such as insufficient water supply, blocked water outlet or poor gas supply.
The reason:
1. The water quality is not clean, containing rust stains or foreign bodies.
2. The handpiece cable is blocked in the water.
3. The water inside the handpiece is blocked.
4. Insufficient or unstable gas supply pressure.
The solution:
1. Ensure that the water quality is clean and free of rust and foreign matter.
2. Unclog the handpiece cable and water.
3. Adjust the gas supply pressure to the normal range, and adjust it to the best working state according to the handpiece model and brand.
What make high-speed handpiece sound is abnormal, the speed is slow or the cutting force is small？
Phenomenon: There are problems such as abnormal sound, decreased speed or insufficient cutting force during the use of the handpiece.
The reason:
1. The diamond bur is bent and deformed.
2. The back cover of the handpiece is loose.
3. Bearing damage.
4. Cutting pressure is too large or too small.
The solution:
1. Replace the standard diamond bur to avoid the use of bent and deformed diamond bur.
2. Tighten the back cover of the handpiece to ensure that the handpiece is secure.
3. Replace the damaged bearing.
4. Adjust the cutting pressure to the appropriate range to avoid too much or too little damage to the handpiece.
Why high-speed handpiece is vulnerable or short life？
Phenomenon: Dental high-speed handpieces are frequently damaged or have a short life during use.
The reason:
1. Overload use, such as continuous work for a long time or excessive pressure.
2. Improper maintenance, such as not timely cleaning, lubrication or replacement of worn parts.
3. Use inferior diamond bur or do not follow the correct use method.
The solution:
1. Avoid excessive use of handpieces, and arrange work time and rest time reasonably.
2. Clean, lubricate and maintain the handpiece regularly to ensure that the handpiece is in good condition.
3. Use regular standard diamond bur and follow the correct method of operation.
Precautions in the daily use of dental high-speed handpiece
1. Check whether the water and air out of the leather cord of the handpiece are normal. Clean water without rust stains and foreign bodies, and dry and clean compressed air are the two prerequisites for the normal use of the dental handpiece.
2. Try to avoid the dental handpiece and the handheld sandblasting machine using the same pipeline to prevent residual sand from entering the handpiece and damaging the bearing.
3. Adjust the appropriate air pressure, generally the working pressure of high-speed handpieces is 0.20-025MPa, the working pressure of low-speed handpieces is 0.25-0.30MPa, different brands of handpieces have differences, which should be adjusted according to the actual situation, the comprehensive treatment table with standard configuration is equipped with two high-speed interfaces, and one handpiece is used for a period of time (10min is appropriate). Replace the use of another handpiece, two handpiece exchange, which can greatly alleviate the impact of "fatigue" on the life of the handpiece bearing, can extend the life of the handpiece, according to statistics, 60% of the handpiece is damaged because of "fatigue".
4. Dental handpiece must use the regular standard car diamond bur, do not idle when the car diamond bur is not clipped or the standard car diamond bur.
5. Do not overload each dental handpiece. Overheating and excessive oral tissue debris will accelerate its wear and tear.
6. Do not immerse the handpiece in corrosive disinfectant. The quick connector of the handpiece does not need high temperature disinfection, and can be wiped with medical alcohol.
In summary, the most common problems with dental high-speed handpieces include the failure to clamp the car diamond bur, water or gas supply problems, water leakage at the connection, abnormal sound and vulnerability. In view of these problems, corresponding solutions and preventive measures can be taken to ensure the normal use of handpieces and extend their service life.
Although the dental handpiece is small in size, it is an indispensable and important tool in oral clinical treatment. Due to the large number of dental outpatient patients, the number of dental handpieces is limited, which can not be used by special aircraft, and the frequent use, repeated high-temperature disinfection will also cause wear and tear to some parts of the handpiece, so the dental handpiece has the characteristics of fast rotation cycle and easy to wear. Although there are many brands of handpieces available on the market, most of their use, repair and maintenance methods are universal.
There is a product that can do the daily maintenance of high-speed handpiece. Dental Handpiece Cleaning and Lubrication Machine(dental equipment): Dental Handpiece Cleaning and Lubrication Machine automatically cleans and lubricates dental handpieces. Ensures smooth operation, extends handpiece life. Quick and convenient, reduces downtime.
