RETRACTED: Development of a Systematic Course On Orthodontic Temporary Anchorage Devices (TADs) for Orthodontic Residency Program

Abstract

Background: Orthodontic temporary anchorage devices (TADs) offer absolute anchorage for clinical orthodontics. No systematic course on TADs has been described so far. The objectives of this study were to develop a systematic course on orthodontic TADs and to determine its teaching outcome.Methods: Five modules (fundamentals, anatomic sites, clinical applications, complications and insertion techniques, FACCI) were designed in this FACCI course on TADs. A total of 61 orthodontic graduate students from Department of Orthodontics, West China Hospital of Stomatology, Sichuan University were enrolled in this study. Baseline levels on the use of TADs were surveyed through a before-course questionnaire and the teaching outcomes were assessed through an after-course questionnaire.Results: After the course, significantly more students were willing to insert TADs by themselves (p<0.001). Students were significantly more familiar with the clinical applications of TADs for different types of tooth movements (p<0.001) and the insertion techniques of TADs at different anatomic sites (p<0.001). Before the course, most of the students had no knowledge on addressing TADs-associated complication and they were significantly more familiar with the techniques and skills of addressing TADs-associated complication after the course (p<0.001).Conclusions: The FACCI course on orthodontic TADs was effective and promoted the clinical applications of TADs in clinical practice among orthodontic graduate students.
