The ability of absolute anchorage systems to create skeletal anchorage has revolutionized the field of orthodontics over the past 20 years, turning cases that were on the verge of surgery into non-surgical ones, extraction cases into non-extraction cases, and even creating an aesthetic effect that was challenging for traditional mechanics to accomplish. Mini-implants or micro-screws, which have an inter-radicular site of placement, are the most often used skeletal anchorage devices. Early loosening during treatment is the most frequent drawback, while their major advantage is the simplicity and minimally invasive installation techniques. With the introduction of Orthodontic Bone Screw (IZC and Buccal shelf TADs), an appropriate balance was reached. These screws not only had an extra-radicular site of placement in the buccal shelf area of the mandible and the infra-zygomatic crest of the maxilla, but they also had significantly lower failure rates than standard mini-implants. The aim of this case report to overview IZC TAD and its efficacy for full arch distalization.
