Swedish orthodontists' opinions and experiences regarding miniscrew implants.

Miniscrew implants (MSI) can be a useful tool when maximal anchorage is desired in ortho- dontic treatment.The aim of this study was to describe the opinions and experiences of mini- screw implants among orthodontists currently practising in Sweden. A web-based anonymous questionnaire containing 17 multiple choice questions was sent to 218 listed members of the Swedish Association of Orthodontists during fall 2012. Descriptive statistics were used for analysing the collected data set. In a total of 147 (67%) respondents 80 were women, 62 were men and five did not specify gender. MSI had been used by 78 (53%) respondents in orthodontic treatment.The majority of the respondents, 53 (70%), had used i-io MSI.The majority of MSI placements were made by orthodontists (84%) while 18 (9%) referred the procedure to an oral surgeon. The most common indications for MSI were space closure, intrusion, and bodily movements. The use of MSI enabled 61 (81%) of the respondents to set higher treatment objectives.The suc- cess frequency of the MSI was perceived as satisfactory by 48 (65%) of the respondents.
