Initial arch wires for tooth alignment during orthodontic treatment with fixed appliances

Over recent years a number of new materials (various metal alloys, or mixtures, of nickel and titanium (NiTi)) have been developed which manufacturers claim offer benefits in terms of tooth alignment. Clinical trials of these products in people undergoing orthodontic treatment are required to understand whether different types of initial arch wires actually result in important differences, such as faster alignment, reduced pain or reduced side-effects, during orthodontic treatment. The Cochrane Oral Health Group undertook this review of existing studies to identify and assess the evidence for the effects of initial arch wires of different materials, shape and size of cross-section for alignment of teeth with fixed orthodontic braces in relation to alignment speed, root resorption and pain intensity. 9 trials were included, with 571 participants.

Traumatic injuries to upper front teeth in children and young adults are common. The Cochrane Oral Health Group conducted this review to look at interventions to treat the front permanent (adult) tooth or teeth when they have been displaced from their original position following injury. This review does not include teeth that have been completely knocked out (avulsion). No studies were identified which met the inclusion criteria.
