Tractional forces: This delivers the tooth out of the socket. This force should be
gentle and the tooth should not be pulled out of the socket. The final movement by
which the tooth is removed from its socket should be always directed outwards, so
reducing the trauma to the opposing teeth and preventing slipping of the tooth in the
mouth which may be swallowed or aspirated by the patient.
If the tooth dose not yield (no movement) after applying a reasonable force,
excessive force should not be used, stop and re-evaluate the case clinically and/or
radiographically because the tooth may be need surgical extraction.

Rotational pressure: Here the tooth is rotated resulting in internal socket expansion
and tearing of periodontal ligaments. This force must only primarily applied to the
teeth with single and conical roots. Teeth with multiple or dilacerated roots are prone
to fracture on the primary application of this force. So rotatory movements or figure
of 8 movement are useful in completing the removal of such teeth previously
loosened by other means and this is called secondary rotatory movement.
