What is a dental high-speed handpiece used for?

Today, we will explain what a high-speed dental handpiece is. A high-speed dental handpiece is not a mobile phone with a fast internet connection. Instead, it is a commonly used instrument in dentistry. It mainly consists of a high-speed turbine head, a handpiece, and air-water tubing. It uses high-pressure air to drive the turbine head to produce high-speed rotation, driving the cutting tool to perform drilling, grinding, and cutting operations on teeth. Dental handpieces can produce a high-speed rotation of 350,000-400,000 revolutions per minute, allowing the cutting tool to quickly and efficiently complete dental treatment operations. Dental handpieces can be matched with different cutting tools to achieve various functions such as drilling, grinding, and cutting teeth, meeting different treatment needs. Currently, most high-speed dental handpieces use stainless steel as the main material. Its characteristic is that it can withstand high-temperature and high-pressure sterilization.

Step 1: Please insert the plug on the measuring line into the jack on the side of the host and turn on the power switch. When the battery display appears in the upper left corner of the screen, it indicates that the measuring instrument is working properly and measurement can begin. Step 2: If the volume of the buzzer needs to be adjusted, please press the volume adjustment button until the volume is suitable. Step 3: Please hang the curved metal lip hook on the measuring line on either corner of the patient's mouth, allowing it to contact the oral mucosa as a reference electrode. Step 4: Clamp the root canal needle with the clip on the measuring line, and slowly move the root canal needle towards the apex. When it is less than 2mm away from the apex, there will be a continuous alarm sound. Step 5: In the power-on state, press the power button to turn off the instrument. The instrument will automatically shut down after 5 minutes of inactivity.

Why is there no sound from the root canal length measuring instrument? Is it broken?

Some users have found that their root canal length measuring instrument suddenly loses sound, greatly affecting their work. Let's analyze why this happens. 1. Usually, if the instrument loses sound, it's because the battery is dead and the machine has automatically shut down. 2. If the machine is still on, it's possible that the volume button was accidentally pressed, putting it in silent mode. 3. If neither of the above is the case, there is a problem with the host machine, and it needs to be sent to the manufacturer for repair.

How is the root canal length measuring instrument determined?

Root Canal Length Measurement: The curved metal lip hook on the measuring line is hung at either corner of the patient's mouth, contacting the oral mucosa as a reference electrode. When the root canal file reaches the apex, adjust the rubber stop on the root canal file to the crown reference point (incisal edge or groove edge). Then remove the measured root canal file and measure the length from the tip of the root canal file to the rubber stop. This is the working length of the tooth. Note: When it is inconvenient to measure posterior teeth using a file clamp, a probe can be used instead of a file clamp.

Generally, upon receipt, you will find the host, measuring line, lip hook, file clamp, probe, adapter, and charger. 1. Adapter Connection: Place the host flat on the desktop. Hold the adapter connector in one hand and insert it into the corresponding charging port on the left or right side of the host. When the adapter connector is fully inserted into the charging port, and the power is connected, the indicator light will turn red, and the host will not be able to power on, indicating a successful connection. If charging is not needed, the adapter can be unplugged. 2. Measuring Line Connection: Insert the file clamp and lip hook into the two ports of the measuring line. Insert the measuring line plug into the port on the right side of the host. A line connection test must be performed before each use. Press the power switch and confirm that the LCD screen displays the image for measuring the root canal working length. Touch the file clamp clip on the measuring line with the lip hook and confirm that the root canal length indicator bar on the LCD screen is fully displayed and stably displays the number "-1". Otherwise, it indicates that the file clamp or measuring line is damaged and must be replaced.
