A retrospective study of factors contributing to anchorage loss in upper premolar extraction cases
Conclusion: Compared with treatment-related factors, the patient's physiological characteristics play a more important role in anchorage loss. The pre-treatment angulation of the maxillary first molar is the most influential factor in changes to maxillary molar angulation, which are often predisposing anchorage loss.
