Among the recent innovations in orthodontics, one of the most significant—skeletal anchorage—opens up new possibilities for complex cases, consolidating our reputation for excellence in dental care. This innovative technique uses temporary anchorage mini-screws as anchor points to move teeth with precision and efficiency. It is particularly useful for treating complex cases that would otherwise require more invasive or lengthier methods. In this article, I will explain what skeletal anchorage involves, its benefits, and how we use it at the Dental Geneva practice to achieve excellent results for our patients.
Understanding temporary anchorage devices (TADs)
A Temporary Anchorage Device, which I employ in my practice, involves temporarily implanted mini-screws into the bone to act as a fixed and sturdy support during tooth movement. This method enables highly precise dental adjustments without the need to involve other teeth or external devices.
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:
- Insufficient traditional anchorage: When traditional methods are inadequate, particularly due to the need for large movements or the loss of dental supports, TADs provide essential support.
- Reduction of visible appliances: For patients concerned about aesthetics or comfort, this method minimizes the use of extensive orthodontic appliances.
- Pre-prosthetic orthodontics: Complex dental movements required for prosthetic preparations, such as the ingression or straightening of molar axes, are facilitated by this technology.
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
Dr. Bruno Gauthier, a specialist in implants at Dental Geneva, performs the placement of TADs. He selects the appropriate type of TAD—long or short—based on each patient’s specific needs and the type of dental movement required. Despite their small size, these devices are extremely robust and are implanted into the jaw.
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.

Placement protocol
The insertion of TADs is conducted under local anesthesia with stringent protocols to minimize any risk. A comprehensive clinical and radiographic examination always precedes the insertion to avoid critical anatomical structures. The placement is generally quick and can often be accomplished without incisions, reducing post-operative discomfort.
Practical applications in orthodontics
Temporary anchorage devices revolutionize the treatment of many complex orthodontic issues, including:
- Correction of severe malocclusions: These devices effectively correct complex malocclusions without intensive surgery.
- Closure of spaces without extraction: Large gaps can be efficiently closed, avoiding the need for extracting healthy teeth.
Conclusion
Embracing TADs at Dental Geneva underscores my dedication to excellence and innovation in orthodontic care. This technology not only transforms treatment possibilities but also improves the patient experience by providing less invasive and more effective solutions.
