关节盘可复性前移位患者再定位咬合板治疗后髁突位置及上气道变化
Changes in condyle position and upper airway of patients with reducible anterior disc displacement after anterior repositioning splint treatment
摘要
Abstract
Aim:To explore the changes of condyle position and upper airway of patients with reducible anterior disc displacement after treatment of anterior repositioning splint.Methods::A total of 21 patients with reducible anterior disc displacement were treated by anterior repositioning splint for 6 to 8 months.Cone beam CT were taken and related indexes were measured by three-dimensional analysis software before and after the treatment to evaluate the changes of joint space,condyle position and upper airway.Results:After treatment,the anterior joint space decreased,the superior joint space and the posterior joint space increased(P<0.05).Before treatment,85.7%of bilateral condyles were in the posterior position and 14.3%in the median position,after treatment,78.6%of bilateral condyles were in the anterior position and 21.4%in the median position.After treatment,the total volume of the upper airway,palatopharyngeal volume,palatopharyngeal mini-mum section,palatopharyngeal height,glossopharyngeal height,palatopharyngeal sagittal diameter,glossopharyngeal sagittal diameter,and palatopharyngeal coronal diameter increased,while the ratio of sagittal to coronal diameter of the palatopharyn-geum and glossopharyngeum increased(P<0.05).Conclusion::Anterior repositioning splint could effectively adjust the condyle position,relieving the clinical symptoms and improving the structure and shape of the upper airway.关键词
