Background and study aims In this study, we intend to determine whether stainless steel springs are as effective as Nickel Titanium (NiTi) coil springs in orthodontic space closure during orthodontic treatment. If we can show that stainless steel springs work as effectively in terms of the rate of space closure, this will be an important finding with respect to orthodontic care and health care expenditure. The aims of this study were to: Compare the rate of orthodontic space closure between NiTi coil springs and stainless steel springs during fixed appliance treatment. Compare the cost effectiveness of NiTi coil springs and stainless steel springs in orthodontic space closure. Who can participate? Patients currently receiving orthodontic treatment in Countess of Chester Hospital and University of Manchester Dental Hospital. What does the study involve? In general, patients currently receiving orthodontic treatment who require orthodontic space closure between the first permanent molar and canine are suitable for this trial. All subjects who are eligible for inclusion will be interviewed and the purpose of trial will be outlined in written information sheets. Once consent is obtained, the patient will be randomly allocated to receive the stainless steel or nickel titanium spring as part of our routine space closing treatment. An impression of their teeth will be taken for study records at the start and completion of this trial. Apart from these, all participants will undertake the same routine treatment, as other non-trial patient would have. At the end of the trial, an examiner will take measurements of initial distance of space to be closed and after completion of space closure to determine the rate of space closure for each type of spring. What are the possible benefits and risks of participating? The possible benefits are rapid orthodontic space closure and shorter treatment time. There are no significant risks or burdens for participants apart from the additional 5-10minutes during treatment time to undertake 2 sets of teeth impressions (study moulds) before and after the study trial commence Where is the study run from? This trial has been set up in Orthodontic Department, Countess of Chester Hospital and University of Manchester Dental Hospital. When is the study starting and how long is it expected to run for? This trial started in April 2011 and ran for one year until April 2012. However this trial may extend beyond this to collect, analyze and publish the data. Who is funding the study? There was no cost involved in purchasing these springs, as they were already available in the clinic. However, indemnity for this trial as has been provided by The University of Manchester.
