It gives the fitting surface in the dental handpiece. There are three different shank styles are available for dental burs. In the dental lab bur, the shank is attached with the high-speed motor while in the dentist bur the attachment is slow of the high-speed handpiece.

1, Friction Grip (FG)

A small cylindrical shank that fits into a handpiece and builds a strong attachment surface. It is used for both carbide and diamond materials. A high-speed handpiece is best suited for friction grip shank style. The sizes of FG diamond burs are available in a very flexible range.

2,Right Angle (RA)

It is also referred to as the Latch-Type shank design of the dental bur. One side of the shank is straight, while the other has a latch attached to the piece of the hand.

3, Handpiece (HP)

The other name is a straight handpiece design. The shank is cylindrical and straight. Diamond cutting disc head is most widely found in long straight piece shanks. The slow-speed handpiece gives the best cutting quality.

In 1979, a specific numbering system was introduced by the international standards organization for dental burs. They give the 15-digit code that is divided into 6 parameters with 3 digits of each code.

The first 3 unique for the material and cutting edge of the bur. the second 3 digits are for the shank design of burs, and the next 3 digits are for the specifications for the length of the total bur. The fourth dight code unique diamond grits. The fifth pair represent grit finesse and coarse surface the and last three codes for bur head diameter.

Dental milling tools: with the technology of cad cam dentistry and optional dental milling system, there are various of cad cam dental milling burs for choice: milling system, application of dental zirconia blocks, lithium disilicate blocks, pmma dental blocks, cobalt chrome dental blocks, etc.
