Which tooth has maximum anchorage value?

Which teeth has maximum anchorage value?

The maxillary canines, because of their long roots can be the most difficult teeth to move in certain clinical circumstances. Number of roots: The greater the surface area of the root, the greater the periodontal support and hence, greater the anchorage potential.

What tooth can be used as absolute anchorage?

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.

How do you reach max in anchorage?

Maximum anchorage in the maxilla can only be achieved by using headgear worn full-time or by using an implant. As full time wear requires considerable patient cooperation, we describe a technique for use of the Straumann Ortho Implant, exemplified by a case presentation.

How can anchorage loss be prevented?

Use of skeletal anchorage systems.

What is an anchor for braces?

Anchors for braces are screw like dental implants which are made of titanium alloy. They are usually only used during a few months during treatment and are then removed. The reason they are used is to create a stable anchorage that is able to be moved.

What is leeway space dental?

INTRODUCTION. Leeway space is the difference in size of the mesiodistal crown widths of the primary canines and molars compared with that of their permanent successors (canine, first and second premolars; Figure 1).

What is a temporary anchorage device in orthodontics?

Temporary Anchorage Devices, or TADs, are small titanium anchors used for the purpose of providing orthodontic anchorage, and are removed at the completion of treatment. They may be used in certain cases to help fix more complex orthodontic problems and achieve quicker tooth movement with more efficiency and comfort.
