There is limited data on how temporary anchorage devices (TADs) are currently used in orthodontics. The aim of this study was to survey two groups of orthodontic providers-graduate orthodontic residencies and private practitioners-about their use.
A 15-question survey was prepared and administered to all 61 accredited orthodontic residencies and an equal number of private orthodontic practitioners (all in the United States). A second survey was also included and provided to the residency programs.
The response rate was 63.9% for private practitioners and 70.4% for orthodontic residency programs. The majority of the residency programs (82.9%) and practitioners (69.2%) reported placing TADs in their practices. TADs were placed in 6.0% of the patients treated by private practitioner and in 5.3% of patients treated in residency programs. A combination of topical and local anesthesia was the anesthetic of choice for 59.0% of private practitioners and 65.0% of orthodontic residency programs. A large majority of the private practitioners (79.0%) and orthodontic residency programs (61.9%) reported that the TADs were loaded immediately. The most frequently cited use for TADs was anterior en masse retraction. In total, 27.9% of the residency programs used miniplates, compared to 17.9% of the practitioners.
Since 2005, a large number of US programs have incorporated TADs into their didactic/research curriculum and residency programs. Both mini-implants and miniplates may have a far-reaching impact on the clinical practice of orthodontics for decades to come. This survey detailed the trends and differences between practitioners and residencies in the TAD utilization experience and provided important information that is otherwise not available in the literature.
关于临时锚固装置（TADs）目前在正畸治疗中的使用情况，相关数据有限。本研究的目的是对两组正畸治疗提供者——正畸研究生住院医师和私人执业医师——的使用情况进行调查。
准备了一份包含15个问题的调查问卷，并发放给所有61个经认可的正畸住院医师项目以及数量相同的私人正畸执业医师（均在美国）。还包含了第二项调查问卷并提供给住院医师项目。
私人执业医师的回复率为63.9%，正畸住院医师项目的回复率为70.4%。大多数住院医师项目（82.9%）和执业医师（69.2%）报告在其临床实践中使用TADs。私人执业医师治疗的患者中有6.0%使用了TADs，住院医师项目治疗的患者中有5.3%使用了TADs。59.0%的私人执业医师和65.0%的正畸住院医师项目选择局部和表面麻醉联合使用作为麻醉方法。绝大多数私人执业医师（79.0%）和正畸住院医师项目（61.9%）报告TADs是立即加载的。TADs最常被提及的用途是前牙整体后移。总体而言，27.9%的住院医师项目使用微型钛板，而执业医师中这一比例为17.9%。
自2005年以来，美国大量项目已将TADs纳入其教学/研究课程和住院医师项目中。微型种植体和微型钛板在未来几十年可能会对正畸临床实践产生深远影响。这项调查详细阐述了执业医师和住院医师在TADs使用经验方面的趋势和差异，并提供了文献中未有的重要信息。
