Which is better for a low-speed dental handpiece, external water or internal water?

Hello everyone, today I'll answer a question many friends have asked: low-speed mobile phones have external and internal waterways, but which one is better? Actually, the difference between external and internal waterways lies in whether the water is outside or on the bending and straightening machines. Generally speaking, external waterways are cheaper. If you need a more cost-effective option, you can choose an external waterway. However, if you find connecting water pipes to an external waterway too troublesome, then an internal waterway is definitely your best choice.

What are the outer and inner waterways of a dental low-speed handpiece?

What are the outer and inner waterways of a dental low-speed handpiece?

Hello everyone, today I will explain the difference between the low-speed mobile phone's external waterway and internal waterway. The external waterway is where water enters the pneumatic motor, and then passes through an external hole of the pneumatic motor via a water pipe to the bending machine. Since the water does not enter the bending machine, it is called the external waterway. The internal waterway is where water enters the pneumatic motor and then directly enters the bending machine, and the water exits directly from the bending machine's water outlet. It's the same as a high-speed mobile phone. Actually, all the functions are the same, only the difference between the external waterway and the internal waterway.

What is the speed of a dental slow-speed handpiece?

What is the speed of a dental slow-speed handpiece?

How fast does a low-speed dental handpiece actually rotate? First of all, the operation of a low-speed handpiece relies on a motor. The typical rotational speed of an air motor is 20,000-30,000 rpm. The motor speed is constant, but different procedures require different conditions and therefore different speeds. This is why handpieces with ratios such as 1:5, 20:1, and 16:1 exist.

What are the precautions for dental low-speed handpieces?

What are the precautions for dental low-speed handpieces?

Hello everyone, today I'll be talking about precautions for low-speed handpieces. First, the operating air pressure for low-speed handpieces is generally set to 0.3-0.35 MPa. Refer to the instruction manual for different brands. Regularly check air pressure stability to avoid affecting device performance due to changes in the usage of the treatment table. Use standard burs with a diameter of 1.59-1.6mm, and match the length to the model (19/21/25mm). Strictly prohibit the use of blunt or bent burs. When installing, ensure they are fully inserted into the chuck. Failure to follow the above instructions may easily cause problems with the low-speed handpiece, leading to a long wait for repairs.

What product is a endo motor with apex locator?

Many people have heard of root canal expanders and root canal length measuring instruments. However, many people have not heard of integrated root canal length measurement and expansion devices. This device looks like a root canal motor (root canal expander), but it has a cable similar to a root canal length measuring instrument. It combines the functions of an expander and a measuring instrument, allowing for simultaneous expansion and measurement. This simplifies the process and eliminates the need to constantly monitor the root canal length measurement data during expansion, as the measured length is displayed on the screen. This makes the process more convenient and efficient.

Is it better to cure with a light curing machine for 1 second or 5 seconds?

Is it better to cure with a light curing machine for 1 second or 5 seconds?

There are many light-curing options on the market today, with different brands and different choices. This leads to a common question: is 1-second curing better than 5-second curing? Actually, different light intensities are better suited for different applications. For example, orthodontics may require a higher light intensity, but some doctors say that 1-second curing is better for certain resins. However, other doctors say that lower light intensity and slower curing is better for some resins. Does this mean you need to buy two curing lights to solve this problem? Actually, you don't. [Brand Name] now offers an adjustable light curing unit, allowing you to adjust the light intensity as needed—high or low. This easily solves all the problems.

Do you know the little tricks for low-speed dental handpieces?

Do you know the little tricks for low-speed dental handpieces?

Today, I'd like to share a little trick for low-speed handpieces. This trick can easily help you solve the problem of the motor not rotating. First, lubricate the motor, then connect it to the dental chair, and then run it dry without water. If it doesn't rotate, adjust the air pressure slightly higher to drive it. This should basically get it rotating. Motors also need lubrication; without it, the gears inside will wear out quickly.

How should I maintain a low-speed dental handpiece?

How should I maintain a low-speed dental handpiece?

Today, I'll talk about how to maintain a low-speed dental handpiece. Dental handpieces require meticulous maintenance because they are essential tools for dentists, significantly improving work efficiency. However, neglecting maintenance will lead to malfunction. So, how should we maintain them? Attach the oiling tube to the rear of the straight handpiece and inject oil into the tube; attach the oiling tube to the rear of the contra-angle handpiece and inject oil into the tube; inject oil into the bur hole and the second largest hole of the motor to ensure internal lubrication. Many people mistakenly believe that low-speed handpieces don't need oiling maintenance. In fact, low-speed handpieces are the same as high-speed handpieces. Without lubrication during rotation, they will quickly be damaged. Proper maintenance is necessary for the motor, contra-angle handpiece, and straight handpiece.

Is a photocuring machine only capable of curing?

Is a photocuring machine only capable of curing?

Many people think that light curing machines only serve to cure. However, with the advancement of times, more and more innovative products are slowly being introduced. This product, for example, can not only cure resin but also perform caries detection. It features blue light curing and purple light caries detection, achieving two functions in one machine. It can both cure and detect caries, which is very convenient. However, currently, there aren't many such two-in-one products on the market. This is because mainstream products still focus on one-second curing, which is currently the most popular type of light curing.

What are the advantages of dental instrument manufacturers?

Many people don't know where to find sources when exporting dental instruments, and often don't find manufacturers. The advantage of manufacturers is that they have first-hand sources. Factories produce and ship directly, ensuring the quality assurance period. Furthermore, factory prices can be lower than those from external channels. However, factories have the pressure of factory rent, water and electricity, and labor costs. Therefore, factories focus on volume; purchasing large quantities from a factory can provide significant advantages.
