axis burs dental

A slender cylinder crafted for dental procedures, axis burs (also called AB) are indispensable tools for dentists. Varied in length from 18 to 25 mm and in diameter from 0.8 to 1.2 mm, these burs make oralsurgery a breeze; they can be used to form canals, ready cavities, and divest aged fillings.

Axis burs are usually constructed from either high-speed steel (HSS) or carbide. Although HSS is more cost-effective than its alternative, it tends to be liable to faster wear and can generate considerable vibration during use compared to carbide.

Costlier than their HSS counterparts, carbide burs offer superior resilience that keeps them sharper for longer periods. Besides, these burs also conduct their tasks without any typical vibration, making them the ideal choice for more intricate projects.

When it comes to dental needs, there is an array of axis burs available. The round varieties are perfect for sculpting canals and cavities, while the oval shapes are ideal for taking out fillings. On the other hand, tapered versions are best suited for fitting canals.

When it comes to axis burs, there are three types of cuts available – cross-cut, straight-cut, and taper-cut. The cutting edge of the cross-cut bur is oriented perpendicular to the shaft. The cutting edge of the straight-cut bur, however, runs parallel to the shaft. On the other hand, a taper-cut bur has a tapered cutting edge.

The axis burs come in three standard sizes – 2, 4, and 6 – and their designation stems from the size of the shaft. Specifically, 2-sized burs are 0.8 mm in shaft diameter, 4-sized burs measure 1.0 mm across the center of the shaft, and 6-sized burs are 1.2 mm in diameter.

With a connected high-speed handpiece, the dental drill is used to make the axis burs whirl at controlled velocity. Each adjustment to the drill’s speed will affect the rapidity of rotation, allowing for a speedy or subdued mobility according to the desired result.

Axis burs enable dental professionals to create smooth, perfectly formed canals and prepare the necessary cavities. In addition, these tools come in handy when it comes to erasing old fillings and refining the edges of cavities in order to make them free from any abnormalities. Last but not least, they are an ideal way to discard any excess cement which may be lurking around crowns and bridges.

Prices vary when it comes to burs due to the material they are crafted from, as high-speed steel options are relatively cheaper while carbide counterparts cost more but last longer. HSS burs may not be as durable but they are less expensive than their carbide varieties, while carbide burs remain sharp for extended periods despite the steep price tag.

A variety of burs come in differing forms and magnitudes; the most popular models are round, oval, or tapered while the standard dimensions are 2, 4, and 6.

A high-speed handpiece links the burs to the dental drill, allowing for adjustable rotation speeds. When faster motion is desired, the speed of the drill can be increased to increase how quickly the bur rotates.

Canals, cavities, and fillings are shaped and smoothed using burs, while crowns and bridges are cleared of superfluous cement with the same instrument. These tiny tools also make ready cavities and eliminate prior filings.
