Temporary anchorage devices (TAD’s) provide Dr. Carlson with a fixed, immovable anchor that makes many tooth movements easier. Uprighting molars, molar intrusion, closing spaces and correction of anterior open bites  are some of the movements made easier by the placement of TAD’s. Temporary anchorage devices are temporary micro implants that look like a miniature version of a screw.  The screw is about the width of the head of a pin. It is generally made of Titanium steel, and is placed painlessly with a mini-“screwdriver”.  The procedure takes a few minutes once the local anesthesia has taken effect. These microscrews are generally placed next to the teeth in front or back of the mouth, on the roof of the mouth or the check side of the mouth.  Springs or rubber bands can be attached from the TAD’s to individual teeth or archwires.

TAD’s are an example of absolute anchorage inside the mouth that can be utilized to perform movements difficult or impossible by other means.  Many times extractions can be avoided, asymmetry more easily treated and in some cases, jaw surgery can be avoided by the use of TAD’s.  Another advantage is that other auxiliaries such as headgear are not necessary, the treatment results are faster and it reduce compliance.  Dr. Carlson  will explain the specific purpose for the placement of TAD’s  as it applies to your treatment.

There is generally little or no discomfort in using or removing TAD’s. The actual removal takes less than a minute and causes no pain.  A minor complication is that approximately 15 – 20% loosen during use.  If the TAD is slightly loose, it can sometimes still be utilized.  If it loosens significantly, it can be removed and replaced in a slightly different area.

TAD’s have been used in orthodontic for 10 to 15 years and our use has been  9 plus years, without any complications.  Please feel free to ask any other questions you may have regarding the placement of TAD’s as an integral part of your orthodontic treatment.
