Usage of temporary anchorage devices: A cross-cultural and cross-sectional survey of orthodontists in Australia and the UK

Introduction > Detailed insight regarding the use of temporary anchorage devices (TAD) in Australia and the United Kingdom (UK) is lacking. The primary aim of the present cross-sectional survey was to investigate TAD usage among UK -based and Australian -based orthodontists. The secondary objectives were to compare TAD -related preferences and protocols between orthodontists in the two countries. Methods > A pilot -tested electronic questionnaire was distributed to members of the British Orthodontic Society and the Australian Society of Orthodontists. Questions pertained to their demographic details, and current use of TADs including protocols, treatment objectives and factors influencing their use. Results > A total of 192 responses were recorded (Australia: 122; UK: 70). One hundred and fortytwo respondents (74.0%) reported using TADs as part of their orthodontic treatment, 77.0% in Australia (n = 94) and 68.6% in the UK (n = 48). Molar protraction was the most common procedure for which TADs were reportedly used (Australia: n = 118; 87.2%, UK: n = 36; 75.0%). "Loosening" was the most prevalent reported complication overall (n = 124; 90.1%). "Confidence", "insufficient postgraduate education" and "availability of equipment" were the factors that most influenced the decision not to provide TADs. Conclusions > Most orthodontists in both countries provided TADs. TAD protocols of orthodontists in both countries were reported. Similarities and differences regarding TAD -related clinical practices and procedures, complications and factors influencing the use of TADs and reasons for not using TADs were explored. Information from the present study can provide baseline data for future related studies in each country and for comparison of TAD usage in other countries.
