Anchorage control in orthodontic treatment is an important factor affecting treatment results. In the conventional approach, intra-oral anchorage such as application of differential force and moment, Nance holding arch and lingual arch, as well as extra-oral anchorage such as head gear were used for anchorage reinforcement. However, these anchorages may result in undesired tooth movement and require patient cooperation. To overcome these disadvantages, skeletal anchorage system was introduced as orthodontic anchorage. Types of skeletal anchorage include implant, onplant, miniplate and miniscrew. Especially, miniscrew has many advantages such as reduced patient cooperation, low cost and easy placement. Recently, it is successfully used in orthodontic treatment. This cases were treated using orthodontic miniscrews for retraction of ectopically erupting maxillary canine and impacted mandibular canine and intrusion of maxillary incisors.
