The combination of Temporary Anchorage Devices (TADs) and elastic devices has significantly expanded the possibilities for precise and controlled tooth movement in orthodontics. Traditionally, elastics have been used in conjunction with teeth to generate inter-arch or intra-arch forces, which often resulted in anchorage loss or unwanted reciprocal movements. TADs have revolutionized this process by serving as absolute, non-dental anchorage points, allowing elastics to deliver targeted forces without relying on other teeth for support. This synergy enables clinicians to move specific teeth or segments more efficiently and predictably, particularly in complex cases like Class II or III corrections, open bites, and asymmetries.
One of the most effective uses of TADs with elastics is in anterior retraction or molar protraction, where elastics are stretched from brackets or buttons on teeth to a TAD placed in the buccal or palatal region. This approach minimizes side effects such as flaring of anterior teeth or mesial drift of molars. It also helps in achieving true bodily movement rather than tipping, which improves both esthetic and functional outcomes. In open bite or vertical control cases, vertical elastics can be anchored to palatal or posterior TADs to intrude molars, promote mandibular autorotation, and close the bite effectively without requiring surgery or patient-dependent devices like headgear.
