General characteristics, types

Dental burs and cutters are in the form of a rod, at one end of which there is a working part, and at the other end - a shank. They are driven by a drill. High RPM while spinning creates a force that relieves plaquedamaged tissue and dental materials.

Cutters and burs are produced for dentists of various specialties:

  • therapeutic;
  • surgical;
  • orthopedic (for dental technicians).

According to the material produced, there are:

  • carbide;
  • of steel;
  • diamond coated.

By the shape of the working part:Hog cutting

  • round;
  • lance-shaped;
  • spear-shaped;
  • cylindrical;
  • conical;
  • reverse conical;
  • in the form of a disk.

By slicing:

  • very large;
  • large;
  • small;
  • super small.

Shank shape:

  • for a turbine machine;
  • for the contra-angle;
  • for a straight handpiece.

Distinctive features

Below is a comparative description of both types of rotary instruments with the main differences:

Name Working part size Material from which they are made Where are used What are they used for?
Bora 0.1 to 0.8 cm From any possible Turbine, straight, contra-angle handpiece Therapy, surgery, orthopedics
Cutters 1.0 to 2.0 cm Predominantly carbide Straight tip Predominantly orthopedics

It follows from the table that the cutters are of a larger size, are made of carbide material, mainly for orthopedic work (processing of prostheses). Burs have a wider range of applications.

Burs: characteristics, types, application

These rotary instruments are presented in various modifications.

Who are used

Burs are used in the work of dentists of all specialties: therapists, surgeons, orthopedists:

  • to remove carious tissues and form a cavity for a filling;
  • grinding and polishing the finished filling;
  • separation of the tooth piece by piece to remove it;
  • preparation of the coronal part for prosthetics.


They have many modifications:

  • diamond of various grain sizes - for therapeutic dentistry;
  • steel with fine notch - removal of softened dentin from a carious cavity;
  • diamond with a large notch - for surgical and orthopedic work;
  • carbide - used for tooth extraction.
Preparation burs

Preparation burs

How are used

The tail part is placed in the drill head and fixed there (depending on the handpiece - automatically or with a special clamp). It is advisable to work in the patient's mouth with water cooling to avoid overheating of soft and hard tissues. Denture treatment should be carried out with air extraction.

Cutters: characteristics, types, application

These rotating tools have a narrower application.

Who are used

Dental cutters are essential for the work of orthopedic dentists and dental technicians outside the oral cavity. Main area of ​​application - initial processing and polishing removable dentures, adjustment bridge structures and crowns.


They differ from each other in the shape of the working part and are:

  • spherical;
  • pear-shaped;
  • conical;
  • reverse conical;
  • in the form of a disk.

When processing individual sections of the prosthesis, the doctor individually selects the specific shape of the working part. For coarse grinding, disc-shaped, pear-shaped tools of large size are used, for polishing - ball drills with a fine notch.

How are used

They have a long shank and are suitable mainly for a straight handpiece. The cutter is fixed by a locking mechanism in micromotor. To work with this group of instruments, it is necessary to have an air extraction system to remove plastic chips from the prosthesis.
