Intrusion is done in orthodontics to correct an anterior deep bite or in some cases intrusion of the over-erupted posterior teeth with no opposing tooth. Intrusion, in orthodontic history, was initially defined as problematic in early 1900s and was known to cause periodontal effects such as root resorption and recession. In terms of stability of anterior open bite treatment using TADs to intrude the posterior maxillary teeth, a study by Baek et al. There are several modalities for intrusion but active intrusion can be achieved by temporary anchorage devices or TAD’s. Introduction: Temporary anchorage devices (TADs) have been shown to be effective in the treatment of VME and/or bimaxillary protrusion but literature focus has been on maxillary miniscrews and not on the efficacy of mandibular TADs.
