Orthodontic mini-implant pins
Orthodontic Mini-implants: ( or mini implant anchors ) are small screws that are placed into the jaw bone to provide a temporary anchorage point. The procedure is usually performed comfortably with a minimum of local anaesthetic. They are in place for a period of several months and are usually simple to remove. Mini-implants make it possible to move a tooth (or a group of teeth) without pulling on the other teeth in the arch.  Mini- implants facilitate certain tooth movements that are otherwise impossible.
Recorded complications using mini-implants have included premature loosening, and it is also possible to inadvertently insert the implant into delicate structures.
 Occasionally mini-implants may break during their insertion or removal. In this example mini-implants were used to assist space closure.
