Mini-screw implants, measuring about 8-10mm in length, are sometimes used to provide an additional source of anchorage to help move the teeth around during orthodontic treatment. They are inserted through the gum, into the jaw bone, under local anaesthesia. These screws are made of titanium or stainless steel. They are removed at the end of orthodontic treatment.
An elastic thread is used to apply force on the upper canine tooth, using the mini-screw implant as anchor. Ceramic brackets are used in the upper jaw; less costly metal brackets are used in the lower jaw.See also: Protruded teeth and Dental implants
