7. Mechanical Properties
Widge Wheel and axleLever

8. Lever
Elevators primarily.
Purchase point can be made
and a crane pick can be used
to elevate the tooth.
Straight elevator help mobilize
teeth without the preparation
of a purchase point.

9. Widge
1) Extraction Forceps
2) Small Elevators

10. Wheel and Axle
Triangular Elevator
Multiple-rooted tooth is
left in the alveolar
process

11. Forceps Use
Goals of forceps:
a) Expansion of bony socket
b) Removal of tooth from sockets
1) Apical Pressure
Bone expansion
Center rotation
2) Buccal Pressure
3) Lingual Pressure

12. Forceps Use
4) Rotational Pressure
Maxillary incisors
Mandibular premolars
5) Tractional Force
For delivery!

13. Forceps Use
Variety of forces can be used to remove a tooth.
Apical force is always useful and should be always used
when forceps is adapted.
Most teeth are removed by combination of buccal and
lingual forces.
Rotational movements are useful for single-rooted conical
teeth with no severe curvatures at the root end.
