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.
