During the extraction of permanent molars, which movement is primarily employed?

In the extraction of permanent molars, the primary movement used is the buccal movement, which plays a crucial role in the successful removal of these teeth. This technique involves applying pressure towards the buccal (cheek) side while simultaneously using rotational and vertical movements to help loosen the tooth from its socket. The buccal movement helps in overcoming the resistance offered by the periodontal ligament and bone, ensuring that the tooth can be extracted more easily.

The technique is particularly important for molars due to their multiple roots, which tend to have complex anatomical relationships with surrounding tissues. By directing the force buccally, dental practitioners are better able to disengage these roots from their bony attachments without causing unnecessary trauma to surrounding tissues.

Other movements, while possibly beneficial in a supportive role during extraction, do not primarily facilitate the removal of molars as effectively as the buccal movement does.
