Principle of elevator use of all the following EXCEPT.. widening the socket wall

Principle of elevator use of all the following EXCEPT:

  • 1- wheel and axle.
  • 2- widening the socket wall
  • 3- wedging.
  • 4- lever.

The principle of (widening the socket wall) is not a typical principle of elevator use in dentistry.

Here's why:

- Wheel and axle:

This principle applies to elevator handles, where rotating the handle creates a mechanical advantage to apply force to the blade tip.

- Wedging:

This is the primary principle behind elevator use. The blade acts as a wedge to separate the tooth structure from the surrounding bone or ligament.

- Lever:

Similarly, the elevator handle acts as a lever to amplify the force applied to the blade tip.

Main Functions Of an Elevator:

Widening the socket wall isn't directly involved in using an elevator. While the elevator might slightly displace the surrounding bone during wedging, its primary purpose is not to widen the socket. The main functions of an elevator are to:

- Section a tooth:

Break a tooth into smaller pieces for easier removal.

- Luxate (loosen) a tooth:

Separate the tooth from the surrounding bone and ligament.

- Elevate (lift) a tooth:

Dislodge and remove the loosened tooth from the socket.

Therefore, while other principles mentioned are integral to elevator function, widening the socket wall is not a direct or intended purpose of their use.
