In order to improve orthodontic anchorage, orthodontic implants or temporary anchorage devices (TADs) are temporarily anchored to the bone, either by supporting the reactive unit's teeth or by eliminating the need for the reactive unit altogether. Extra-alveolar TADs are placed away from roots. Infra-zygomatic crest screws, the buccal shelf screws andramal screwsare some of the commonly used extra alveolar implants. They help in various tooth movements like en-mass distalization, intrusion, uprighting, mesialization etc. The purpose of this review is to discuss the type of screw utilised, its size, the locations where extra-alveolar TADs are placed, the indications for its usage, and any unique concerns when treating malocclusion in all three dimensions without damaging reciprocal forces.
