Dental Bur Shapes And Their Uses

Write in brief on dental our design.
Answer:

Dental Bur is a small milling cutter.

“What Are The Different Shapes Of Dental Burs Used In Dentistry”

A dental bur has three parts head, shank, and shaft.

1. Head: Portion carrying the cutting blades.
2. Shank: Portion connecting the head to the shaft.
3. Shaft: Portion which will be engaged within the handpiece.

“Best Ways To Understand Dental Bur Shapes And Their Uses”

Design of dental bur:

• Blade or cutting edge: It is in contact with the horizontal line of work.
• Tooth face: Sides of tooth ahead of cutting edge in the direction of rotation.
• Back or flank of the tooth: The opposite side of the face.
• Rake angle: The face of the bur tooth is at an angle to the radial line from the center of the cutting edge.

“Early Signs Of Problems With Dental Bur Performance”

• • Negative rake angle: If the face is ahead and leading the radial line in reference to the direction of rotation, the angle formed between the face and radial line is
    called negative rake angle.
  • Zero or radial rake angle: if the face is on the radial line the rake angle is zero.
  • Positive rake angle: When the radial line leads the face so that the rake angle is on the inside of the radial line.

“Importance Of Selecting The Right Dental Bur Shape For Procedures”

• Clearance angle:
  • The angle between the back of the tooth and the work is known as the clearance angle.
  • The angle between the land and the work is called the primary clearance angle and the angle between the back and the work is known as the secondary clearance angle.
• Land: The plane surface immediately follows the cutting edge.
• Tooth angle: It is the measurement between the face and the back or between the face and land.
• Flute or chip space: This is the space between successive teeth.
