ANCHORAGE IN ORTHODONTICS
Keywords:
Anchorage, Anchorage planning, Anchorage loss, Skeletal anchorage.Abstract
During orthodontic treatment, the teeth are exposed to forces and moments, and according to Newton's third law, these acting forces always produce reciprocal forces that are of the same magnitude but the opposite direction. These reciprocal forces must beappropriately diverted in order to prevent unintended tooth movements and sustain treatmentsuccess.One of the main reasons for unsatisfactory outcomes in orthodontic treatment and a potential adverse effect of orthodontic mechanotherapy is anchoring loss. Multiple factors, including the extraction site, appliance type, age, crowding, and overjet, have been identified as its causes.In order to manage anchorage, clinicians have worked hard throughout the years to identify biomechanical solutions. This article's goal is to review the fundamentals of anchorage and anchorage planning in various appliance systems.
