What is High Speed Handpieces

High speed handpieces can be electric or air-driven. They provide precision control for rapid, efficient removal of tooth structure and margin creation at high RPMs with little to no pressure, vibration, or heat thanks to friction grip burs. The small head size maximizes visibility and maneuverability.

 

Benefits of the high-speed handpiece in dentistry:

There are different options available in the high-speed handpiece and each handpiece will come with a certain advantage. So, you need to work on every single option to find the one that suits you.

Here are a few benefits of using the high-speed handpiece;

No matter how stronger the cutting power may be, a high-speed handpiece doesn’t emit any pressure or heat
It benefits the patients in a number of ways, as the patients will feel less pain and comfort during the treatment, and also the procedure will get done quickly
If you use the high-speed handpiece, there won’t be any pulp death
The dentist will be able to get more precise cuts through teeth and bone
The dentist will find it easier to use the handpiece for cleaning, cutting, and other dental procedures
Different types of high-speed handpieces:

Air turbine handpiece
The air-turbine high-speed handpiece mostly relies on the air-driven turbine, and it will make the instrument rotate. This is the most popular option in the air-turbine handpiece, and it rapidly removes the tooth structure, without damaging the pulp.

The handpiece comes with an ergonomic weight and size, and also it cost relatively low in terms of purchase and repair. These types of air-driven handpieces start functioning at 400,000rpm, but they will operate between 180,000 and 330,000rpm. But this type of handpiece comes with a disadvantage as, despite the high speed, its relatively low-torque causes the bur to slow down when it endures the heavy loads.

Electric handpiece
The electric-driven high-speed handpiece will use an electrical supply that will power the motor through the control unit. These types of handpieces will be heavier, bulkier, and also more expensive than the air-turbine handpiece. Here, the torque is constant, and also it will perform well under demanding loads, so offers better cutting.

This handpiece comes with a number of different motor attachments, so depending on the need, the rpm of the handpiece can be increased. So, the dentist can use this handpiece for both high-speed and low-speed endodontic procedures.

45 degree contra-angle handpiece
450 contra-angle handpiece combines the benefits of the surgical straight and contra-angle handpiece, and it works well for patients having a smaller mouth as the instrument will get easily accessed. The instrument will come with a professional cooling system and tiny attachment head, which will cover the thermal effects and unobstructed work.
