Anchorage has been a worrisome factor since the origin of orthodontics. Many modalities have been suggested in the scientific literature like extraoral anchorage with head gears, Intraoral anchorage with Nance palatal arches and reinforcement of anchorage units with addition of second molars, etc. Yet, the specialty of orthodontics did not find a solution for this problem until the introduction of miniimplants. Orthodontic implants are different from the ones used for prosthetics as there is no osseointegration. Mini-implants provide absolute anchorage and have revolutionized the field of orthodontics. This article reviews the indication, contraindications and their clinical applications in orthodontics.
