ORTHODONTICS : Serial extraction of primary teeth


The term serial extraction describes an orthodontic treatment procedure that involves the orderly removal of selected deciduous and permanent teeth in a predetermined sequence.

Serial extraction can be defined as “the correctly timed, planned removal of certain deciduous and permanent teeth in mixed dentition cases with dento-alveolar disproportion in order to: Alleviate crowding of incisor teeth.

Serial extraction can be defined as “the correctly timed, planned removal of certain deciduous and permanent teeth in mixed dentition cases with dento-alveolar disproportion in order to: Alleviate crowding of incisor teeth.

Thus it is one of the positive interceptive orthodontic procedure generally applied in most discrepancy cases where supporting bone is less than the total tooth material.

Justification for serial extraction:
Dental crowding – The result of inadequate arch size, insufficient basal bone, and / or excessive tooth material – is epidemiologically the most common type of malocclusion.

It can be eliminated by making the dental arch larger or reducing the amount of tooth material.

Expansion of the dental arches by orthodontic alignment may be possible if the tooth material is not too excessive.

However, the stability of expansion may well be compromised by the insufficient alveolar basal bone.
