Measured arch perimeter(MP) The arch-perimeter was directly measured on the plaster models from the vertical line marked on the distobuccal cusp of maxillary second molars with a 0.010inch stainless steel ligature wire that contacted the buccal surface of each posterior tooth and labial surfaces of each anterior tooth. The wire was marked at distobuccal cusps with a marking pencil, and then it was straightened and laid flat on a graph paper.
