It has been suggested that more effective anchorage reinforcement may be offered by surgically placed temporary anchorage devices.There is little evidence to support the use of surgical anchorage systems over conventional means of orthodontic anchorage reinforcement. However there is evidence from one recent trial that showed mid-palatal implants are an acceptable alternative to conventional techniques for reinforcing anchorage.
