What attachments fit into the high speed handpiece?

What attachments fit into the high speed handpiece?

Some features available on some high-speed dental handpieces can include fiber optics, electric or air driven, construction material, burr attachments and water and air ports. These attachments have “E” couple connections. Many vendors also offer lubricated handpieces as well as lube-free high-speed handpieces.

What is the chuck on a handpiece?

Chuck. The part in the handpiece turbine used to hold the bur.

What are the three basic parts of a dental handpiece?

Three basic parts to a rotary instrument:

  • Shank: Portion that fits into the handpiece.
  • Neck: Portion of the rotary instrument that connects the shank and the head.
  • Head: The cutting, polishing, or finishing portion.

What is a high speed dental handpiece?

High speed handpieces. 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.

What two attachments are used on the low speed handpiece?

Part 2: Attachments for Slow-speed Handpieces. There are 2 basic types of attachments used with slow-speed motors: nosecones and contra angles. A nosecone is a straight attachment that will accept a slow-speed bur or a shaft-driven angle (contra angle or prophy angle).

What type of burs does the high speed handpiece use?

Diamond burs are most commonly used with high speed handpieces, meaning they are most commonly available as a friction grip shank. Diamond is the hardest material available and is used to grind away tooth tissue, usually enamel. The grinding motion of a diamond bur leaves a rough finish.

How many RPM can the high speed handpiece reach?

High-speed handpiece. High-speed handpieces work at cutting speeds over 180,000 rpm. They are technically categorised into air turbine and speed-increasing depending on their mechanisms. In a clinical setting, however, air turbine handpieces are most often referred to as “high-speeds”.

What Kind of bur system does the high speed handpiece use?

How does a high speed handpiece work?

A high-speed dental handpiece is considered to be a device of precision. It removes tooth tissue in a fast and highly efficient manner. It does not result in heat, pressure increases, or vibrations. These are typically utilized for polishing the teeth and the actual shaping of crowns and fillings.

What is the rpm of the high speed handpiece?

between 250,000 and 420,000 rpm
Air-driven high-speed handpieces typically will have speeds between 250,000 and 420,000 rpm but the torque is relatively low, whereas an electric handpiece may have speeds around 200,000 rpm but relatively high torque.

How fast does the high speed handpiece operate?

approximately 400,000 RPM
What is a High Speed Handpiece? A hand held drill, usually air-driven (can also be electric), that spins cutting burs at approximately 400,000 RPM. Used for cavity preparation, removal of tooth structure and margin creation.

What is the slow speed handpiece used for?

Low-speed handpieces are used for the removal of soft decay, finishing cavity preparation, polishing, trimming and prophy work.

How does handpiece work?

How Does a High Speed Handpiece Work? Air turns a turbine located in the head (front) of the handpiece. The turbine consists of two miniature bearings, an impeller, and a spindle/chuck assembly that holds the bur. Air is introduced into the handpiece via the chair unit foot pedal, goes through the airline attached to the back end of the handpiece, up through the handpiece shell, and

What does handpiece mean?

medical Definition of handpiece. : the part of a mechanized device designed to be held or manipulated by hand; especially : the handheld part of an electrically powered dental apparatus that holds the revolving instruments (as a bur)

What is a dental handpiece?

A dental drill or handpiece is a hand-held, mechanical instrument used to perform a variety of common dental procedures, including removing decay, polishing fillings, and altering prostheses.
