The objectives of this study was to evaluate the awareness of different ceramic bracket debonding techniques among orthodontists in the USA and the most commonly used debonding technique for ceramic bracket removal.
A survey on preference for debonding and awareness of debonding techniques was emailed to 2,227 members of the American Association of Orthodontists (AAO).
119 orthodontists completed the survey. 111 responses were included in the study analysis of ceramic bracket users. The most common technique used was mechanical debonding. 86.5% used a specially designed bracket removing plier from the manufacturer. Overall, there were 59.5% of surveyed orthodontists who were aware of electrothermal debonding, 73% were unaware of ultrasonic debonding and 83.8% were unaware of laser debonding. There were more orthodontists with an affiliation with an academic institution aware of electrothermal debonding (=0.002). There also was a trend of orthodontists having no affiliation with an institution who were unaware of laser debonding (=0.015).
This survey showed that the majority of orthodontists who responded to the questionnaire were unaware of alternative debonding techniques of ceramic brackets. All orthodontists who use ceramic brackets utilized mechanical debonding technique. Orthodontic ceramic brackets, mechanical, electrothermal, ultrasonic, laser debonding.
本研究的目的是评估美国正畸医生对不同陶瓷托槽去粘结技术的认知情况以及最常用的陶瓷托槽去除技术。
向美国正畸医师协会（AAO）的2227名成员发送了一份关于去粘结偏好和去粘结技术认知的调查问卷。
119名正畸医生完成了调查。111份回复被纳入陶瓷托槽使用者的研究分析。最常用的技术是机械去粘结。86.5%的人使用了制造商专门设计的托槽拆除钳。总体而言，59.5%的受访正畸医生知晓电热去粘结，73%的人不知道超声去粘结，83.8%的人不知道激光去粘结。与学术机构有关联的正畸医生中知晓电热去粘结的更多（P = 0.002）。没有机构关联的正畸医生中不知道激光去粘结也存在一种趋势（P = 0.015）。
本次调查表明，大多数回复问卷的正畸医生不知道陶瓷托槽的替代去粘结技术。所有使用陶瓷托槽的正畸医生都采用机械去粘结技术。正畸陶瓷托槽、机械、电热、超声、激光去粘结。
