In the context of extraction, which teeth are generally preferred for orthodontic anchorage?

In orthodontics, the teeth that are preferred for anchorage during extraction are generally the first premolars. When the first premolars are extracted, it allows for the retraction of anterior teeth without significant loss of anchorage, as first premolars are positioned anteriorly and the extraction creates space for the alignment of the remaining teeth.

Selecting first premolars for extraction is beneficial because their removal facilitates a more favorable distribution of forces during orthodontic treatment, allowing the remaining teeth, including the canines and incisors, to move into the created space. Additionally, this choice minimizes the impact on occlusion and maintains the posterior occlusal stability.

In contrast, extracting second molars or first molars generally results in greater challenges for anchorage as these teeth play critical roles in maintaining posterior support and occlusal function. Removing them may lead to unwanted movements of other teeth and may compromise the overall occlusion and stability of the dental arch.
