The Role of Arch Width in Late Lower Arch Crowding

There is a strong tendency for untreated lower arch ţo became more crowded in the postadolescent period. The cause of this late increase in crowding is obscured by its multifactorial nature. This study was undertaken to investigate the influence of anterior and posterior arch width to late lower arch crowding. A group of 123 subjects with lower arch crowding was compared with a group of 51 subject without crowding. The distance between distal surfaces of the lateral incisors, the lower intercanine width, and the upper intermolar width was smaller in the group with crowding, while the lower intermolar width didn&#8217 ; t show statistically significant difference. The anterior arch width was correlated with crowding much more than the intermolar width. Our results suggested that narrow arches, particulary in the anterior part, is an important characteristic of late lower arch crowding.
