FACULTY FILES TADs in ORTHODONTICS: a Review By Glen Roberson, DMD, Clinic Director & Assistant Professor, College of Dental Medicine, Henderson Campus, Roseman University of Health Sciences I n orthodontics, anchorage is an important factor to consider during the treatment planning process. Failure to consider anchorage can create a vast array of treatment anomalies, including increased treatment time, compromised case results, and increased costs for the orthodontist. As such, any device that may help the orthodontist to establish the necessary anchorage, whether used during the entire course of treatment or for only a portion thereof, should be considered. One such device is a temporary anchorage device (TAD) or skeletal anchorage device. TADs have become valuable tools in the orthodontist's armamentarium, allowing for anchorage situations that were at one time unachievable without the full compliance of the patient. used for restorative purposes, TADs are designed such that osseointegration is not the primary method of retention. Instead, the screwlike design allows the threads of the TAD to engage the cortex of the alveolar bone in the area of insertion. As such, the quality and thickness of the cortical bone have been shown in studies to be a factor in the success rate of TADs in orthodontic use.1-4 TADs The design of the TAD also contributes to the simplicity of inserting the device. Most, if not all, of the newer TAD designs employ both a selftapping and self-drilling construction. Self-tapping DESIGN TADs are designed and manufactured to be both functional and easy to use. They are constructed primarily of surgical-grade titanium with a polished surface that allows for not only good biocompatibility, but also for ease of removal at the completion of treatment.
