[Clinical results of bone anchors for orthodontic anchorage; the indications and surgical complications].
In order to make teeth-movement possible, orthodontic anchorage is necessary. Neighbouring teeth, a headgear, dental implants and bone anchors can be used. During the period 2002-2007 158 bone anchors have been placed in 84 patients by an oral surgeon after referral by an orthodontist in order to achieve anchorage for orthodontic treatment. The bone anchor consists of a titanium osteosynthesis-plate ending in a round neck perforating the soft tissue and a cylinder attached to it. The indications for placement, results and complications were registered. 15 anchors (9,5%) were lost prematurely and in 13 cases (8,2%) complications needing surgical intervention were reported. It is concluded that zygoma-bone anchor is a good alternative for orthodontic anchorage and the number of complications is acceptable, though there is room for improvement.
