Comparison of Patient-reported Pain After Initial Archwire Placement With Three Types of Nickel-titanium Archwires: a Prospective Triple-blind, Randomized Controlled Clinical Trial
University of Colorado, Denver
Summary
Three different types of 'archwires' can be used in Orthodontic treatment, wire choice is decided by treating Orthodontist based on professional preference since research shows that all types are equally effective. It is possible that one type of wire engenders more patient discomfort. This study will compare the discomfort levels engendered by the three wire types to determine if there is one that induces the least amount.
Description
Orthodontic treatment with fixed appliances has the potential to induce pain in patients. At the beginning of treatment, the orthodontist must determine which initial orthodontic archwire to insert. Among the more popular choices for initial leveling and aligning of the dental arches are small-sized, round-diameter nickel-titanium archwires. Various types of nickel-titanium (NiTi) archwires exist including stabilized martensitic wires (ie classic Nitinol), active austenitic wires (superelastic NiTi) and active martensitic wires (thermoelastic NiTi). The efficacy of these wire types has been he…
