Study of the adaptability of preformed orthodontic archwires to the average dental arch form of a Moroccan population

Of the 25 archwires tested, 10 correspond perfectly to the average dental arch form of our sample at canine and molar level (mean ± 1SD) and would be suitable for cases where the treatment plan involves no expansion. In addition, 3 archwires have a shape that is slightly wider than the average arch form in the sample and could be used for cases in which the treatment plan includes no extractions but simply a slight expansion.
