They allow tooth movements that are difficult or impossible to achieve reliably with braces or aligners alone, significantly expanding what can be accomplished during the adolescent growth years without surgery.
At Lusk Orthodontics, TADs are used as part of complex adolescent treatment plans where standard mechanics would be insufficient, giving patients access to a level of precision and capability that was not available to previous generations of orthodontic patients.
Closing Extraction Spaces
When teeth have been removed as part of the orthodontic plan, or when severe crowding requires extraction, TADs allow remaining spaces to be closed efficiently without unwanted movement of the anchor teeth. Space closure over significant distances is more predictable and better controlled with skeletal anchorage than with tooth-to-tooth mechanics.
Correcting Severe Bite Problems
Closing Anterior Open Bites Without Surgery
An anterior open bite where the front teeth do not make contact when the back teeth are together is one of the more complex problems in orthodontics and is prone to relapse. In adolescent patients, TAD-supported intrusion of the back teeth allows the bite to close at the front as the jaw autorotates. This can achieve significant open bite correction without surgery, and doing so during adolescence when the tissues are responsive and growth can be used advantageously often produces more stable outcomes than treatment attempted in adulthood.
Load moreConventional orthodontic treatment uses teeth as anchors. When force is applied to move one tooth, the tooth used as the anchor is subject to an equal and opposite force. This can limit what is achievable, particularly in cases involving significant bite problems, severe crowding, or complex tooth movements.
TADs eliminate this limitation by providing an anchor point fixed in bone that does not move under orthodontic load. This allows forces to be applied with full directional control, enabling tooth movements that would otherwise require surgery or simply could not be achieved.
During adolescence, when the jaws are still growing and the dentition is developing, TAD-supported mechanics can address problems at the optimal biological moment before growth is complete and while the tissues are most responsive.
Placement is a straightforward, minimally invasive procedure carried out in the orthodontic clinic under local anaesthetic. No incisions are required; the mini-screw is placed directly through the gum tissue into the bone. Most adolescent patients tolerate the procedure very well and report only mild pressure during placement and some soreness for one to two days afterwards.
TADs are removed once the tooth movements they were supporting are complete, which is similarly quick and comfortable. In most cases, removal does not require a local anaesthetic.

Read MOREPlacement is done under local anaesthetic and is well tolerated by most teenagers. Mild soreness for one to two days afterwards is common and settles without specific treatment.
Occasionally a TAD becomes mobile during treatment, usually due to the natural bone remodelling around it. If this happens, it can be re-placed in a slightly different position without significant disruption to the treatment plan.
TADs are small and located in areas of the mouth that are not easily visible. Most patients are aware of it initially but adapt quickly and report little to no awareness after the first few days.
Usually, yes — TADs provide the anchorage, while fixed braces or aligners deliver the tooth movements. They are rarely used in isolation.
