A TEMPORARY ANCHORAGE
DEVICE (TAD) is a bone anchor made of titanium that looks like a miniature version of a wood screw. Orthodontists use a TAD to provide an anchor that they can use to move a nearby tooth.
TAD’s
Temporary anchorage devices (TAD’s) for orthodontic anchorage are widely accepted. They are changing the way orthodontists treat some patients’ malocclusions. TAD’s provide a fixed
point from which to apply force to move teeth. Placement is customized for each patient. TAD’s contribute to predictable results, shorter treatment time and completion of active treatment on schedule. There is little or no discomfort when a TAD is placed. Caring for your TAD generally requires only routine brushing.
Although small, the TAD does a big job of helping your orthodontistmove your teeth predictably into their optimal positions.
How long are TAD’s left in?
Your orthodontist will advise you how long a TAD will be needed. It may be only for a few months, or it may be needed throughout your orthodontic treatment. TAD’s are versatile and may be used in different areas of the mouth during different parts of treatment.
What are TAD’s?
TAD’s are titanium-alloy mini-screws, ranging from 6 to 12 millimeters in length and 1.2 to 2 millimeters in diameter. They are fixed to bone temporarily to enhance orthodontic anchorage. Titanium alloys are used as joint replacements and for dental implants for many years. These alloys are rarely rejected by the body.
Where are TAD’s placed?
TAD’s are placed in the bone between the roots of the teeth and can be placed in the bone in the roof of the mouth as well.
