Temporary Anchorage Devices in Clinical Orthodontics

Abstract

The temporary anchorage devices (TADs) have been applied in the clinical setting to achieve various tooth movements. TAD placement has a higher failure rate in adolescents than in adults and thinner and less-dense bone has thus been suggested as a risk factor. The thickness of palatal bone has been found to be a key factor for success of temporary skeletal anchorage devices. The thickness differs depending on age, gender, facial growth type, and ethnic group. Several measurement methods have been reported to assess palatal soft tissue thickness. Direct measurements via a needle or periodontal probe taken under local anesthesia have been reported, as well as non-invasive direct measurements using an ultrasonic device. Indirect measurements using computed tomography (CT) and cone-beam CT images have also been applied.
