Treating various types of malocclusion is dependant on providing a secure anchorage. In this context, it has been shown that teeth, intramaxillary, and/or extraoral appliances are required to achieve favorable outcomes regarding anchorage treatment. A Temporary anchorage device (TAD) has been introduced in the literature in this context. It has been described as a temporary device that can be used after completing treatment. The aim of the study was to review the indications and uses of TADs in orthodontic treatment. The current evidence shows that introducing TADs in the field of orthodontic treatment has been associated with favorable outcomes that encountered the previous multiple challenges reported with the conventional anchorage approaches. Contemporary orthodontic settings reported various uses for TADs, including corrections in transverse, vertical, and anteroposterior dimensions. Combined use of TADs and conventional approaches were also evaluated with favorable outcomes. These findings indicate the validity of TADs in orthodontic treatment and call for its future implications and clinical applications. However, it should be noted that post-treatment evaluation on a long-term basis was not adequately reported in the current literature, indicating the need for future investigations for further validation.

Molar anchorage loss in extraction case is believed due to the reaction of mechanical force applied to retract anterior teeth. While it may be close to truth in adult patients, it is certainly not true in adolescents. Studies on molar growth show upper molar move forward as mandible growing forward, probably through intercuspation force. Hence, for adolescents, molar anchorage loss shall consist of two parts. One is from retraction force — mechanical anchorage loss; another from biologic force — physiologic anchorage loss. Since physiologic anchorage loss is caused by the continuous biologic force, the strategy of physiologic anchorage control (PAC) is different from the strategy of mechanical anchorage control. A new PAC method is introduced in this article that can reduce the headgear and temporary anchorage device used as sagittal anchorage dramatically in orthodontic clinic.
