One of the many important advances in orthodontics has been the development of temporary anchorage devices, or TADs. Made of bio-compatible titanium alloy, TADs are miniscrew anchors which are inserted into specific places in the mouth to be used as a fixed point from which teeth can move. TADs can help Dr Mibab move severely angled, impacted or ankylosed ( fused to bone ) teeth. They are also helpful in achieving orthodontic movement in a mouth with missing teeth.
