American Board of Orthodontics (ABO) Practice Exam

Question: 1 / 660

What is the most important dimension for TAD stability according to Marquezan?

Length

Width

The most important dimension for TAD (Temporary Anchorage Device) stability, according to Marquezan, is width. This focus on width is critical because the stability of TADs is significantly influenced by their contact surface area with the surrounding bone. A wider base ensures better distribution of forces and enhances the biomechanical support provided by the bony anchorage. This increased surface area minimizes the risk of loosening and enhances the overall retention of the device during treatment.

In orthodontics, the anchorage provided by TADs is crucial for effective treatment outcomes. When TADs are adequately stabilized, they can withstand the forces applied during the orthodontic movement of teeth, making the width dimension vital for long-term success. This underscores the importance of considering the dimensions of TADs carefully during planning and placement to achieve optimal results in orthodontic therapies.
