Abstract
An orthodontist attends the scientific orthodontic congress and passing by the company exhibitions receives a free sample of a novel orthodontic archwire introduced in the market for initial alignment/levelling with favourable performance over conventional superelastic nickel-titanium archwires. This novel archwire should increase according to the manufacturer’s claims alignment efficacy and halve the pain for the patient. After using the free sample wire on a patient and observing that the patient felt little to no pain during the alignment/levelling phase, the orthodontist decides to venture into unknown territory and find out if this holds true for most of her patients by doing a randomised clinical trial in her practice.
