2PRINCIPLES OF ELEVATOR AND FORCEPS USE

The primary instruments used to remove a tooth from the alveolar process are the elevator and extraction forceps. Elevators help in the luxation of a tooth, and forceps continue that process through bone expansion and disruption of periodontal attachments.

3PRINCIPLES OF ELEVATOR AND FORCEPS USE

The goal of forceps use is twofold: (1) expansion of the bony socket by use of the wedge-shaped beaks of the forceps and the movements of the tooth itself with the forceps, and (2) removal of the tooth from the socket.

4PRINCIPLES OF ELEVATOR AND FORCEPS USE

• The dental elevator consists of a handle, a shank, and a blade.• Blades can be straight, triangular (Cryer), curved (Potts), or pointed

(Crane pick).

5PRINCIPLES OF ELEVATOR AND FORCEPS USE

• Forceps can apply five major motions to luxate teeth and expand the bony socket: The first is apical pressure, which accomplishes two goals:

(1) the tooth socket expansion (2) the center of rotation of the tooth is displaced apically.

6PRINCIPLES OF ELEVATOR AND FORCEPS USE

• The second major pressure or movement applied by forceps is the buccal force.

7PRINCIPLES OF ELEVATOR AND FORCEPS USE

• Third, lingual or palatal pressure is aimed at expanding the linguocrestal bone .

8PRINCIPLES OF ELEVATOR AND FORCEPS USE

• Fourth, rotational pressure, which causes some internal expansion of the tooth socket and tearing of periodontal ligaments.

9PRINCIPLES OF ELEVATOR AND FORCEPS USE

• Finally, tractional forces are useful for delivering the tooth from the socket once adequate bony expansion is achieved.
