In recent years, miniscrews have come to occupy an ever greater place in orthodontic treatment plans. Today, we now know how to successfully deploy these particularly adaptable anchorage devices. The benefits of miniscrews have led orthodontists to adopt them, all the more so as they do no damage in the event of failure. We present the indications which are more and more evidence-based although these anchorage devices are suitable for use in any situation. We also describe the different surgical and orthodontic stages designed to facilitate the insertion of miniscrews and ensure their success. Several treated clinical cases will illustrate the principles underpinning their use in a variety of clinical settings.
