Abstract

Orthodontic miniscrews have greatly expanded the limit of clinical orthodontics. Orthodontic miniscrews can provide stationary anchorages for various tooth movements and make it possible to move the tooth in directions which have been impossible with traditional orthodontic mechanics even without patients’ cooperation. On the contrary, the clinical use of miniscrew anchorage accompanies some risks and complications. Among them, screw failure is the most complicated concern. Regardless of screw type, miniscrew failure rate was reported 10-30%, which was considerably higher than that of dental implants. Although a lot of factors are proposed for the reason with screw failure, enhancing miniscrew stability is an urgent task. In this presentation, I would like to propose the following two strategies to enhance initial stability of orthodontic miniscrews: 1. Recommendation of oblique placement of miniscrews; 2. Development of a new secure minicsrew with locking structure. Furthermore, the presentation will refer to the miniscrew-assisted orthodontic treatment using a newly developed secure miniscrew. It is hopefully anticipated that this presentation will provide an insight into an integrated orthodontic treatment by use of miniscrews.
