Abstract

The aim of this clinical study was to examine the mandibular flexure in two transverse and longitudinal dimensions of female dental students. Thirty-five fully-dentate female dental students were selected for the study. Intermolar, intercanine and canine to second molar distance in the most open position and occlusion were measured using the Mitutoyo digital calipers. Lower arch width and length change were calculated and proposed as the mandibular flexure. Data were analyzed using one-way ANOVA and paired t-test. The mean reduction of intermolar and intercanine distance at maximum open and closed mouth positions was 0.19 and 0.17 mm, respectively. The mean longitudinal dimensional change of right and left side of the mandible was 0.05 and 0.15 mm, respectively. No significant differences was seen (p = 0.76). It is concluded that mandibular arch width in the posterior and anterior regions decreases at the most open position compared to rest position. Also, Increasing in longitudinal dimension of the lower arch between canine and second molar in maximum open position was seen. © 2012 Asian Network for Scientific Information.
