Temporary anchorage device (TAD): a revolution in orthodontics

Among the most significant recent innovations in orthodontics, the Temporary Anchorage Device (TAD) opens new possibilities for complex cases, reinforcing our reputation for excellence in dental care. This cutting-edge technique uses Temporary Anchorage Devices as support points to precisely and efficiently move teeth. It is especially beneficial for treating complex cases that would otherwise require more invasive or prolonged methods. In this article, I will explain what TADs involve, their benefits, and how we utilize them at Dental Geneva to achieve superb results for our patients.

History and development

Since their development in the early 2000s, TADs have evolved thanks to continuous research. I adopted this technique because it has become a preferred tool for us, orthodontists, aiming to solve complex cases previously deemed too difficult or impossible to manage with traditional methods.

Indications and applications of TADs

The use of TADs is particularly suited to several specific scenarios:

Benefits of TADs

  • Increased control and precision: The stability provided by TADs allows for extremely precise adjustments, crucial for achieving the desired aesthetic and functional outcomes.
  • Reduction in treatment duration: These techniques enable faster dental movements, significantly shortening the overall duration of treatment.
  • Predictability of results: The outcomes I achieve with TADs are highly predictable, enhancing patient satisfaction and optimizing treatment plans.

Types of TADs and application methods

TADs can be:

  • Transgingival: They pass through the gum and delve into the spongy bone. These screws are chosen for their ability to support significant orthodontic loads, necessary in cases of substantial dental movements.
  • Cortical: These screws are shorter and primarily anchor in the cortical bone, used when movements require less force or are more limited in amplitude.

Practical applications in orthodontics

Temporary anchorage devices revolutionize the treatment of many complex orthodontic issues, including:

  • Closure of spaces without extraction: Large gaps can be efficiently closed, avoiding the need for extracting healthy teeth.
