Every dentist is trained to use different types of tools and materials to restore teeth and improve the patient’s oral health.
However, the dental handpiece is the most essential one among these tools.
The teeth are hard and mineralized tissues. Therefore, they are not easy to cut or wear. As a result, when a tooth is fractured or affected by caries, the dentist must prepare it before placing the restoration material. However, due to its nature, it can only be done using rotary burs placed inside a dental handpiece.
Nonetheless, the different types of handpieces and burs are designed to perform additional functions. These functions may range from simply polishing a tooth to fixing a temporary crown restoration.
For this reason, the dental handpiece is the most versatile and practical item in any dentist tools kit.
In this article, we’ll talk about the different types of handpieces, how they work, and their multiple parts.
What Is A Dental Handpiece?
ದಿ ಹಲ್ಲಿನ ಕೈಚೀಲ is a versatile device at the disposal of any dentist. This equipment is a thin handheld device that can be equipped with different types of burs and polishing cups.
These devices have a long handle and a small head at the frontal end. The head is where the dentist places the interchangeable burs, cups, and discs.
The dental handpiece is usually made of stainless steel, which prevents corrosion after being in constant contact with the water it expels and the mouth’s humidity.
Nonetheless, they are designed to be lightweight. This ensures the user’s comfort throughout long working sessions. Furthermore, the handle is ergonomic to prevent hand fatigue and other conditions, such as carpal tunnel disease. This condition can be developed by the strain caused by having an uncomfortable grip or hold.
Furthermore, the handpiece can be sterilized in an autoclave. This prevents cross-contamination between patients.
The handpiece can be either air-driven or electric.
This is the most common type of handpiece. They use the pressurized air from the air compressor to work.
These handpieces are connected directly to the dental unit through the connections in the delivery unit.
They have tubes in their interior where the air and water traverse. These tubes extend to the device’s head, where the activation mechanism is located.
Electric handpieces use electrical currents to activate the spinning mechanism.
Unlike air-driven handpieces, these devices are not connected to the dental unit but to a separate control unit.
This control unit has a panel that the dentist can use to adjust different settings, such as the torque and speed of the rotary bur.
Different Types Of Dental Handpieces
Whether electric or air-driven, handpieces can be divided into two main groups: high-speed/turbine and low-speed/micromotor.
● Dental turbine handpiece:
The dental turbine handpiece, also known as the high-speed handpiece, is the most commonly used type for teeth prepping.
As expected, this device operates at high speed. This allows the bur to cut through the teeth’ enamel easily.
However, its speed can cause heat damage to the dental pulp, and it can also damage the enamel and dentin. Therefore, the ಹಲ್ಲಿನ ಟರ್ಬೈನ್ ಕೈಪಿಡಿ is integrated with a refrigeration system. When the device is activated, its head sprays water directly into the spinning bur. This causes it to cool down while also cooling the tooth.
The amount of water expelled from the high-speed dental handpiece is regulated by the dental unit.
Lastly, some dental turbine handpieces are equipped with a LED light on their head. This improves visibility greatly, especially while working on areas that can be hard to illuminate with the dental unit light.
● Dental Air Motor:
ದಿ ಹಲ್ಲಿನ ಗಾಳಿ ಮೋಟಾರ್ is a specialized type of handpiece that operates at low-speed. This makes it ideal to work safely on the tooth’s dentin.
However, it is essential to understand that the dental air motor is only half of the device. An additional handpiece must be plugged on top of the motor. This top handpiece is where the bur or cup is placed.
Two types of handpieces can be plugged into the dental air motor: a contra-angle handpiece and a straight handpiece.
The dentist uses the contra-angle handpiece to remove caries near the pulp chamber. However, it can also be equipped with cups and discs to polish the patient’s teeth and restorations.
Meanwhile, the straight angle is often used to polish prosthetic restorations using polishing mops. Moreover, the dentist can also use special burs to cut and wear down metallic and acrylic appliances.
The dental handpiece is a delicate device that must be used with care to avoid damaging it. However, as with any other mechanical device, its internal mechanism can wear or damage after prolonged usage.
Fortunately, most of its pieces are replaceable, such as:
● Dental handpiece cartridge:
The dental ಕೈಚೀಲ ಕಾರ್ಟ್ರಿಡ್ಜ್ is the heart of the device. It is the spinning mechanism located inside the handpiece’s head.
The cartridge possesses several bearings that form channels where the water and airflow are.
The bur is connected and secured to this cartridge.
● Dental Handpiece Couplers:
The dental handpiece coupler is the mechanism located at the bottom of the handpiece. It acts as a connection between the handpiece and the hoses in the dental unit. The handpiece coupler has several holes where the water and air pass through.
These couplers come in different shapes according to the handpiece model. There are 3 types available:
1. ISO – A: Commonly used in Latin America and Europe. It lacks an exhaust hole.
2. ISO – B: Commonly used in North America. It tends to have 4 to 5 holes. Furthermore, one of them is a large exhaust hole.
3. ISO – C: This is the latest coupler version developed. It has 6 holes.
