The pear-shaped dental bur for a high-speed handpiece, identified by the code H7.314.008 and universally known in dental practices as bur number 330, is an essential and extremely versatile tool for high-speed procedures. Unlike its low-speed counterparts, this bur connects directly to the high-speed handpiece, which allows it to operate at much higher revolutions and, as a result, achieve superior efficiency and cutting.

First of all, its design is characteristic: the head has a shape that is perfectly reminiscent of a pear, with an oval and slightly elongated body that culminates in a blunt tip. Manufacturers make it primarily from tungsten carbide, a material that not only gives it exceptional hardness for cutting enamel and dentin but also guarantees a long service life even under intensive use.

Regarding its clinical applications, the 330 bur for high-speed handpieces demonstrates remarkable versatility. Dentists frequently use it as the initial instrument to open cavities and access decay, thanks to its safe tip that minimizes the risk of accidental perforation. Subsequently, it is ideal for performing the cariesectomy, that is, for removing carious tissue quickly and selectively, while最大限度地 preserving healthy tooth structure. Likewise, its rounded shape makes it especially suitable for creating the initial anatomical shape in amalgam restorations and for contouring and smoothing the walls of Class I and II Black preparations with great precision.

However, its usefulness does not end there. It is also excellent for performing occlusal adjustments on metal restorations or for grinding down certain dental areas in a controlled manner. The high speed of the handpiece, combined with the safe shape of the bur, gives the clinician supreme control and a cutting capacity that is both aggressive and yet delicate.

In short, the number 330 pear bur for high-speed handpieces is a workhorse in restorative dentistry. Its unique design and its compatibility with the high-speed handpiece make it a tool of choice for procedures that require efficiency, precision, and safety. Therefore, it establishes itself not only as an instrument for removing decay but also as a fundamental solution for shaping and refinement during the most demanding dental treatments.
