The surgical dental handpiece, also known as "drill" -- is the essential dental equipment in all dental practice. A wide assortment of dental handpiece parts manufacturers, dental hygienists, oral health specialists, and lab technicians research dental handpiece and accessories to optimize the oral health of patients all around the world.

No matter it is a standard prophy appointment or a comprehensive surgical treatment is being conducted, the surgical dental handpiece is essential. In this guide, we will outline the differences between high speed dental handpiece and slow speed dental handpiece and other types of dental handpieces. What is Slow Dental HandpieceA Low (Slow) Speed Handpiece is an air-driven or electric-driven handheld motor, which spins the dental burs. The low speed dental handpiece is designed to handle much more air pressure than high speed handpiece. When air is introduced into the handpiece (via the chair unit foot pedal), the air is forced over the vanes of the rotor (consisting of vanes or blades), which causes it to spin. It is widely used in the removal of caries, refining a cavity preparation, performing prophylaxis, and other endodontic and implant procedures. High speed dental handpiece is usually an air-driven or electric-driven handheld drill, which always works with surgical
dental burs. Typically, it is used for cavity preparation, removal of tooth structure, and margin creation. And the working principle is similar to the slow-speed dental handpiece. The air turns a turbine in the head(front) of the handpiece. The dental handpiece turbine consists of two miniature bearings, an impeller, and a spindle/chuck assembly that holds the dental burs. Then, when the air is introduced into the handpiece via the dental chair foot pedal, the air
would over the impeller of the dental handpiece turbine, causing the turbine to spin. High Speed Dental Handpiece VS Slow Speed Dental HandpieceSince I have clearly illustrated the definition of the slow speed dental handpiece and high speed dental handpiece. It is time to outline the differences between them. The differences cover three factors. RPMAs their name implies, they have
different speeds in the operation. Typically, a dental handpiece low speed at a rate of 5,000 to 40,000 RPMs. Because of the low operating speed, this type of dental handpiece tends to have a longer service life than that of high speed dental handpiece. The high speed dental handpiece operates at a rate of 250,000 to 400,000 RPMs. ApplicationsVarious types of dental
surgical dental handpieces are applied to various operations. The low speed dental handpiece is designed for removing soft decay, finishing cavity preparation, polishing, trimming, and prophy work. And the high speed dental handpiece is used for removing tooth tissue at a high operating speed. Therefore, compared with the high speed dental handpiece, the low speed dental handpiece could handle a more delicate job with its slow operating speed, during the operation. In summaryThe high speed one is typically used for preparing teeth while low-speed ones are more appropriate when finishing and polishing restorations. Other Types of Dental HandpieceExcept for these two dental handpieces, there are other commonly used dental handpiece for dental surgery. Endodontic HandpieceThis dental handpiece is specially designed for cleaning and shaping canals during root canal treatments. With the endodontic apex locator and endodontic motor, they are capable of driving endodontic files with precision, regardless of the rotating methods. Implant Dental HandpieceThe implant dental handpiece is specially designed for oral and maxillofacial surgery. The implant dental handpiece is made of good quality stainless steel and covered with a special coating.
Because of it, the implant dental handpiece is highly robust. It generally works with the dental implant burs to complete the surgery. ConclusionAll in all, there are some differences between low speed dental handpieces and high speed dental handpieces, but they are still similar in their working principle. Like other dental handpieces, they play an important role in oral surgery. And most dental equipment suppliers try to research the best dental handpiece for making a contribution to dental surgery. What is the difference between a high speed and low speed dental handpiece?The speed depends upon the pressure (PSI) of the air supply, the configuration of the rotor components, and the gears inside the motor. Low speed handpieces are designed to handle much more air pressure than high speed handpieces.
What is a low speed handpiece used for?Low-speed handpieces are used for the removal of soft decay, finishing cavity preparation, polishing, trimming and prophy work.
What is a high speed handpiece used for?The high speed handpiece is a precision device for removal of tooth tissue efficiently and rapidly with no pressure, heat or vibration and cut the tooth like butter.
How fast does a high speed dental handpiece go?Reaching speeds as high as 420,000 rpm, high-speed air-turbine dental handpieces may outrun electrics, which generally top out at 200,000 rpm, but they lack the torque of the latter, and have been known to stall under load. In fact, their speed may drop as much as 40% or more once their burs hit a surface.
