PDF: The optimal position for insertion of orthodontic miniscrews

The search for orthodontic treatment methods requiring minimal patient compliance while simultaneously providing maximal anchorage has led professionals to use a wide array of devices, such as mini-plates, dental implants and miniscrews.


Miniscrews offer advantages such as their small size, low cost, streamlined insertion and removal surgical procedures and immediate load while providing adequate anchorage to enable orthodontic movements.

Determining what type of orthodontic movement will be used prior to miniscrew placement is of paramount importance because insertion at an unsuitable site is likely to restrain the desired movement. Miniscrews can be inserted in a variety of maxillary and mandibular sites, notably in the interradicular spaces between adjacent teeth as well as in the palate and retromolar area.

Screw length is not associated with stability for screws longer than 5 mm, whereas screw diameter has been significantly associated with stability.
