The aim of this study was to test the hypothesis that unilateral posterior crossbite influences postural stability of the whole body. Twenty-six subjects (14 males and 12 females) affected with unilateral posterior crossbite were selected and compared with 52 controls matched for age and gender. Postural stability was assessed using a stabilometric platform. The following stabilometric measurements were assessed: weight distribution on foot area and speed of body sway. Tests were performed under two occlusal conditions: teeth in intercuspal position (ICP) and while keeping two cotton rolls between teeth without clenching. The weight distribution on foot area and the speed of body sway were not significantly influenced from crossbite (with and without lateral mandibular slide), occlusal conditions (ICP, cotton rolls), and gender. Therefore, the treatment of this malocclusion in order to prevent or to treat postural disorders is not justified.
本研究的目的是检验单侧后牙反合会影响全身姿势稳定性这一假设。选取了26名患有单侧后牙反合的受试者（14名男性和12名女性），并与52名年龄和性别匹配的对照组进行比较。使用稳定测力平台评估姿势稳定性。评估了以下稳定测力测量指标：足部区域的重量分布和身体摆动速度。测试在两种咬合条件下进行：牙齿处于牙尖交错位（ICP）以及在牙齿间放置两个棉卷且不咬紧时。足部区域的重量分布和身体摆动速度不受反合（有或无下颌侧方滑动）、咬合条件（ICP、棉卷）和性别的显著影响。因此，为预防或治疗姿势紊乱而对这种错合畸形进行治疗是不合理的。
