What is absolute anchorage in orthodontics?

Absolute or infinite anchorage is defined as no movement of the anchorage unit (zero anchorage loss) as a consequence of the reaction forces applied to move teeth. Such an anchorage can only be obtained by two means, using ankylosed teeth or using implants, both relying on bone for their anchorage.

What are anchorage devices?

Temporary Anchorage Devices (TADS) are small, screw-like dental implants made of a titanium alloy. As the name implies, they're temporary — they usually remain in place during some months of treatment, and then they are removed.

What structures are used as anchorage?

Intra-oral anchorage: When intra-oral structures such as teeth and other anatomic areas are used as anchor units it is called intraoral anchorage. Mini-screws can be considered as an absolute intraoral anchorage. Extra-oral anchorage: Extra-oral anchorage is the anchorage established from extra-oral structures.

What is an auxiliary wire?

Can malocclusion cause bruxing?
