What is the characteristic grip type for burs designed for high-speed handpieces?

The characteristic grip type for burs designed for high-speed handpieces is the friction grip. This type of grip is essential because it allows for a secure connection between the bur and the handpiece, enabling the high-speed rotation necessary for efficient cutting and drilling. The friction grip utilizes a tapered head design, which provides a snug fit within the handpiece, ensuring that the bur does not slip or come loose during operation. This reliability is crucial in dental procedures, where precision and control are paramount.

In contrast, other grip types, such as latch grip and screw grip, are typically designed for different applications or handpieces. Latch grip burs, for instance, have a specific mechanism that relies on a latch to hold them in place and is commonly used with slow-speed handpieces. Screw grips involve a threaded system that requires tightening, which is also more commonly associated with other tools rather than high-speed handpieces. Snap grip is not a recognized term in the context of dental burs and handpieces. Understanding these distinctions helps clarify why friction grip is integral to the operation of high-speed handpieces in dental practices.
